Booklet Describes Vinyl Coatings For Corrosion Control

A new 20-page, four-color booklet from Union Carbide Corporation discusses the use of vinyl maintenance paints for protecting steel and other substrates from corrosion. The coatings described are one-package systems that can be formulated from solution vinyl resins to comply with current air pollution control regulations, and be applied in as few as one or two coats.

The differences between conventional and high-build vinyl paints, and between vinyl primers and topcoats, are explained in the booklet. Also summarized are the factors involved in choosing zincrich or other primers which meet particular requirements for vinyl maintenance systems. In addition, there is a section that points out where not to use vinyl paints.

Tips on writing specifications for high-performance vinyl systems are presented. An aid to evaluating paint failure is provided in the form of a table that lists particular types of failure, and indicates their possible causes.

A section on using vinyl paints covers surface preparation, application methods and thinning precautions.

Copies of "Vinyl Coatings for Corrosion Control," designated F-46055, can be obtained by writing to J.L. Shalhoup, Union Carbide Corporation, Coatings Materials, 270 Park Avenue, New York, N.Y. 10017.
