EXHIBIT 31.2
                    CERTIFICATION OF CHIEF FINANCIAL OFFICER

I, Rudolph A. Lutterschmidt, Vice President and Chief Financial Officer of
Nocopi Technologies, Inc., certify that

1.  I have reviewed this quarterly report on Form 10-QSB of Nocopi Technologies,
    Inc.;
2.  Based on my knowledge, this quarterly report does not contain any untrue
    statement of a material fact or omit to state a material fact necessary to
    make the statements made, in light of the circumstances under which such
    statements were made, not misleading with respect to the period covered by
    this quarterly report;
3.  Based on my knowledge, the financial statements, and other financial
    information included in this quarterly report, fairly present in all
    material respects the financial condition, results of operations and cash
    flows of the registrant as of, and for, the periods presented in this
    quarterly report;
4.  The registrant's other certifying officers and I are responsible for
    establishing and maintaining disclosure controls and procedures (as defined
    in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal controls over
    financial reporting (as defined in Exchange Act Rules 13a-15(f) and
    15d-15(f)) for the registrant and have:
    (a)  designed such disclosure controls and procedures, or caused such
         disclosure controls and procedures to be designed under our
         supervision, to ensure that material information relating to the
         registrant, including its consolidated subsidiaries, is made known to
         us by others within those entities, particularly during the period in
         which this quarterly report is being prepared;
    (b)  designed such internal control over financial reporting, or caused such
         internal controls over financial reporting to be designed under our
         supervision, to provide reasonable assurance regarding the reliability
         of financial reporting and the preparation of financial statements for
         external purposes with generally accepted accounting principles;
    (c)  evaluated the effectiveness of the registrant's disclosure controls and
         procedures and presented in this report our conclusions about the
         effectiveness of the disclosure controls and procedures as of the end
         of the period covered by this report based on such evaluation; and
    (d)  disclosed in this report any change in the registrant's internal
         control over financial reporting that occurred during the registrant's
         most recent fiscal quarter that has materially affected, or is
         reasonably likely to materially affect, the registrant's internal
         control over financial reporting.
The registrant's other certifying officers and I have disclosed, based on our
most recent evaluation of internal controls over financial reporting, to the
registrant's auditors and the audit committee of registrant's board of directors
(or persons performing the equivalent functions): all significant deficiencies
and material weaknesses in the design or operation of internal control over
financial reporting which are reasonably likely to adversely affect the
registrant's ability to record, process, summarize and report financial
information; and any fraud, whether or not material, that involves management or
other employees who have a significant role in the registrant's internal control
over financial reporting.
