                               FEBRUARY 18, 1998
 
  This Proxy Statement is furnished in connection with the solicitation by the
Board of Directors of the Company of proxies in the accompanying form for use
at the Annual Meeting of Stockholders to be held for the purpose of
considering and acting upon the matters specified in the foregoing Notice of
Annual Meeting. The mailing date of the proxy materials is on or about January
5, 1998.
 
  The Common Stock is the only voting stock of the Company outstanding. At the
close of business on January 2, 1998, 10,353,087 shares of Common Stock were
outstanding and 9,083,925 shares of Common Stock were eligible to vote at the
Annual Meeting (pursuant to the Agreement Containing Consent Order by and
among The Valspar Corporation ("Valspar"), the Company and the Federal Trade
Commission dated September 30, 1993, 1,269,162 shares of Common Stock are
restricted from being voted). Each stockholder of record is entitled to one
vote for each share of Common Stock held on all matters to come before the
Annual Meeting.
 
  A proxy in the accompanying form which is properly signed, dated, returned,
and not revoked will be voted in accordance with the directions noted therein.
If no direction is indicated, it will be voted for the election of the
nominees named herein as directors, for ratification of the appointment of
Ernst & Young LLP as independent auditors and on all other matters presented
for a vote in accordance with the judgment of the person acting under the
proxies. The Board of Directors does not intend to bring any matter before the
Annual Meeting except as specifically indicated in the foregoing Notice of
Annual Meeting, nor does the Board of Directors know of any matters which
anyone else proposes to present for action at the Annual Meeting.
 
  A proxy may be revoked by a holder of Common Stock at any time prior to its
use by the Company by voting in person at the Annual Meeting, by executing a
later proxy, or by submitting a written notice of revocation to the Secretary
of the Company at the Company's office or at the Annual Meeting.
 
  Election of each director requires the affirmative vote of the holders of a
plurality of the shares of Common Stock present in person or represented by
proxy and entitled to vote at the Annual Meeting. Ratification of the
appointment of the independent auditors requires the affirmative vote of the
holders of a majority of the shares of Common Stock present in person or by
proxy and entitled to vote at the Annual Meeting. An automated system
administered by the Company's transfer agent is used to tabulate votes.
Abstentions, directions to withhold authority, and broker nonvotes are counted
as shares of Common Stock present in the determination of whether the shares
of Common Stock represented at the Annual Meeting constitute a quorum.
Abstentions are not counted in tabulations of the votes cast on proposals
presented to holders of Common Stock and neither abstentions nor broker
nonvotes are counted for purposes of determining whether a proposal has been
approved.
 
  The cost of soliciting proxies has been, or will be, paid by the Company. In
addition to the solicitation of proxies by mail, directors, officers, and
employees of the Company may solicit proxies personally, by telephone,
facsimile, letter, or other form of communication at no additional
compensation to them. The Company will reimburse brokerage firms and others
for their expenses in forwarding proxy materials to beneficial owners of
Common Stock.

DIRECTOR COMPENSATION
 
  Employee directors do not receive additional compensation for serving on the
Board of Directors. Non-employee directors receive an annual retainer of
$17,000 payable, at the director's option, either entirely in deferred stock
or half in deferred stock and half in cash. On January 1, 1997, Mr. Stevenson
assumed the title of Chairman of the Board of Directors. In February 1997, the
Board of Directors approved the designation of a Lead Director (non-employee)
of the Company. The Lead Director receives annual compensation of $8,000 more
than other non-employee directors of the company. A non-employee director is
entitled to receive shares of Common Stock represented by the deferred stock
awards when such director ceases to be a member of the Board of Directors.
Each nonemployee director also receives a fee of $1,000 in cash for each Board
of Directors or committee meeting attended, provided that this fee is not paid
for committee meetings held on the same day as a Board of Directors meeting.
Upon his or her initial election to the Board of Directors, each non-employee
director (except for Mr. Harris in his previous role as Chairman of the Board
of Directors) received an initial non-qualified option to purchase 10,000
shares of Common Stock at a price equal to the market value of such shares at
the date of grant. Mr. Harris, in his previous role as Chairman of the Board
of Directors, received an
 
                                       5

 
initial non-qualified option to purchase 35,000 shares of Common Stock at an
exercise price equal to the market value of such shares at the date of grant.
The exercise price for such options for Messrs. Giles, Harris, and Tomfohrde
and Ms. Collins is $16.2125 per share and for Mr. Johnson is $15.00 per share.
 
                SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS
 
  The following information presents the beneficial ownership of shares of
Common Stock as of December 1, 1997 (unless otherwise stated) by (i) each
stockholder known by the Company to be the owner of more than five percent of
the outstanding shares of Common Stock, (ii) each director, (iii) each
executive officer named in the Summary Compensation Table, and (iv) all
directors and executive officers as a group. Except as noted below, the shares
of Common Stock indicated in the following table are held with sole power over
both investment and voting.
 
  This table also sets forth the number of McWhorter Stock Equivalents
credited to the individual's deferred compensation account or equivalents
granted through the Key Employee Annual Bonus Plan. The deferred compensation
account reflects the election of the individual to defer restricted stock and
stock option gains, and/or Company ESOP restoration contributions. The value
of McWhorter Stock Equivalents is determined by the price of McWhorter stock.
Therefore, the value of an individual's account is fully at risk and tied to
McWhorter stock performance. These stock equivalents do not carry any voting
rights.

         COMPENSATION COMMITTEE INTERLOCKS WITH INSIDER PARTICIPATION
 
  During fiscal 1997, Messrs. Giles, Harris, Johnson, and Tomfohrde and Ms.
Collins served as members of the Compensation Committee of the Board of
Directors, none of whom has ever served as an officer or employee of the
Company.
 
         BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
  The Compensation Committee of the Board of Directors is comprised of the
five independent non-employee directors named below. The Committee is
responsible for establishing salaries, incentives, and other forms of
compensation for the Company's executive officers and other key employees,
administering the various incentive compensation and benefit plans of the
Company, and recommending policies related to such incentive compensation and
benefit plans. The Committee has adopted the following as the purpose of the
Company's executive compensation program: (1) retain and attract quality
executives critical to the success of the Company; (2) direct executive
attention to performance measures that are important to stockholders, such as
growth in earnings per share, earnings quality, stock price appreciation, and
full compliance with legal and ethical standards; (3) reward executives for
progress in achieving longer term strategic goals; and (4) promote stock
ownership to ensure that the interests of the executives and stockholders are
closely aligned. The Company's incentive plans are designed to condition a
significant amount of an executive's compensation on the performance of the
Company. The compensation plans are also designed to encourage executive stock
ownership. In its administration of the various compensation programs, the
Committee focuses on these goals of tying compensation to performance and
encouraging executive stock ownership. The compensation program for executive
officers consists of two annual components, base salary and cash bonus, and
three long-term components, grants of stock options, grants of stock
equivalents and awards of restricted stock.
 
  Section 162(m) of the Internal Revenue Code generally limits to $1,000,000
the tax deductibility of compensation paid by a public company to its chief
executive and four other most highly compensated executive officers. Certain
performance based compensation is not subject to the limitation and certain
regulations have
 
                                      10

 
been proposed under Section 162(m). Because the Committee believes the
nonperformance based compensation of each of the executive officers will be
below the Section 162(m) tax deductibility amount for the foreseeable future,
the Committee has not yet taken any specific action or adopted any policy in
this regard.
 
  Base Salary. During fiscal 1995, the Committee adopted a policy that the
base salaries for executives should be set at slightly above the base salary
average for positions of comparable responsibility in selected companies. The
selected companies would consist of at least seven coatings intermediates and
specialty chemicals companies, if possible. Those salaries should be adjusted
over time based upon both the performance of the executives and the
performance of the Company relative to the performance of the peer group.
Based on this analysis, during fiscal 1997 the Committee approved an increase
in the base salaries of Messrs. Stevenson, Nodland, Brolsma, Heffernan, and
Rahrig.
 
  Bonus Programs. One element of the annual compensation plan for executive
officers is the opportunity to earn a substantial cash bonus. These bonuses
are based upon the accomplishment of certain pre-established goals and
criteria. An available bonus amount, expressed as a percentage of base salary,
is established in advance. This places a substantial portion of an executive's
annual compensation at risk. The available bonus amount as a percentage of
salary for the executive officers in fiscal 1997 was 80% (90% for the
President and 100% for the Chairman of the Board). The evaluation criteria are
reviewed, evaluated, and appropriately modified on an annual basis. For fiscal
1997 those criteria were as follows: sales volume, gross margin, earnings per
share and a discretionary component as determined by the Compensation
Committee. The Committee's policy also provides that the Committee, in its
sole discretion and on an individual basis, could consider bonuses for truly
extraordinary performance in an amount not to exceed an additional 50% of base
salary. Pursuant to the bonus program, the executive officers on average
received bonuses equal to 58% of the available bonus. In fiscal 1997, the
Board of Directors adopted the McWhorter Technologies Inc. Key Employee Annual
Bonus Plan. Under this plan, certain key employees may elect to receive all or
part of their bonus in the form of McWhorter Stock Equivalents. With respect
to fiscal 1997 annual bonuses that are deferred in the form of stock
equivalents, the Company also matches 1/3 of such deferral in the form of
additional stock equivalents.
 
  Stock Options and Restricted Stock. The Committee's policy is that the
primary component of long-term compensation for executive officers should be
stock options. The Committee believes that tying the compensation of
executives to the price of the Common Stock is the most effective means of
aligning their interests with those of the Company's stockholders. The
Committee's policy is that executive officers should be granted stock options
at an exercise price equal to the market price at the time of grant and with a
total exercise price, expressed as a percentage of base salary, which is in
the middle of the range of option values granted to executive officers at
comparable publicly-held coatings intermediates and specialty chemicals
companies. Based on this policy, the Committee has granted options to purchase
a number of shares with a total exercise price on the date of grant equal to 2
1/2 times the executive officer's base salary (3 times in the case of the
President and 3 1/2 times in the case of the Chairman of the Board).
Additional options are granted to reflect increases in base salary. The
Committee has not adopted a specific policy on when any other options might be
granted. Nonetheless, options are not granted on an annual basis. Since the
formation of the Company there has been only one option grant (other than
those to reflect salary increases or promotions) to each executive officer.
 
  The other long-term component of executive compensation is restricted stock
awards. Under the current program, restricted shares vest, if at all, over a
five year period, based on a comparison of the Company's earnings per share in
each year to a base year (fiscal 1994). The vesting in each year is also
contingent on the Company's achieving certain return on capital and return on
equity goals. In fiscal 1995 the Committee made restricted stock awards to the
executive officers with respect to a number of shares equal in value on the
date of award to 1 1/2 times the executive officer's base salary. Additional
awards are not made to reflect increase in base salary. These restricted
shares are forfeited to the extent the vesting criteria have not been met
before the end of fiscal 1999. For fiscal 1995, 1996 and 1997 the vesting
criteria has not been met.
 
                                      11

 
  The Committee adopted a policy in fiscal 1994 of awarding shares of Common
Stock as restricted stock annually to those employees (including executive
officers) on whose behalf contributions by the Company to the Company's
Employee Stock Ownership Plan (the "ESOP") and Employee 401(k) Savings Plan
(the "401(k) Plan") are subject to the compensation limitation set by Section
401(a)(17) of the Internal Revenue Code for qualified retirement vehicles. The
number of shares of Common Stock awarded as restricted stock is calculated on
the basis of the difference between the employee's salary and such limitation
amount (currently $160,000) multiplied by the Company's contribution rate to
the ESOP and the 401(k) Plan and divided by the fair market value of the
Common Stock. This policy was supplanted effective October 1, 1996 by the
terms of the Deferred Compensation Plan.
 
  Deferred Compensation. In fiscal 1996, the McWhorter Technologies, Inc.
Deferred Compensation Plan (the "Plan") was adopted by the Compensation
Committee for a select group of management or highly compensated employees.
The Plan became effective October 1, 1996. The Plan provides an opportunity to
defer a portion of base annual salary, annual bonus, restricted stock and
stock option gains on a pre-tax basis. Under the Plan the Company credits the
employee with an amount equal to excess ERISA benefits and the Company may
make discretionary contributions. To date, the Company has made no
discretionary contributions under this plan. During fiscal 1997, all of the
named executives participated in the Plan and the amounts credited by the
Company under the Plan to their accounts was equal to excess ERISA benefits.
To the extent that restricted stock or stock option gains are deferred, they
are required to be deferred in the form of stock equivalents and cannot be
distributed until the individual retires or leaves the Company.
 
  Chief Executive Officer Compensation. In establishing Mr. Stevenson's base
salary, the Committee considered information concerning the salaries of chief
executive officers of other companies in similar industries and of similar
size and complexity and attempted to set levels at or slightly above the
comparable companies. In establishing the multiple of 3 1/2 applied to Mr.
Stevenson's salary in determining the number of shares of Common Stock as to
which he was granted stock options and the multiple of 1 1/2 in determining
the number of shares of restricted stock, the Committee considered information
concerning the potential for long term compensation that was provided by other
companies in similar industries of similar size and complexity. In
establishing Mr. Stevenson's salary and bonus the Committee also considered
the significant financial and strategic achievements of the Company in fiscal
1996 and 1997, (particularly with respect to the discretionary portion of Mr.
Stevenson's fiscal 1997 bonus, the Committee considered the successfully
implemented programs that have substantially accelerated the Company's
improved profitability), and the considerable challenges which have been
inherent in the role of Chief Executive Officer of the Company in its early
years as an independent public company. Pursuant to the annual bonus plan and
the deferred compensation plan described above, Mr. Stevenson deferred his
entire fiscal 1997 bonus in the form of McWhorter Stock Equivalents and
received a 1/3 company match valued at $105,272.
