scope:

The material defined by this specification is a solution of acid catalyst in organic solvents. It is to be used in a polyester top coat system required to provide the best exterior quality finish. It shall be suitable for spray application.

APPLICATION

This specification was released originally for a material to be used as an acid catalyst to make polyester top coats suitable to use with relatively low baking temperatures.

The catalyst shall only be used for top coats from the same source as required by the vendor. The amount of addition may vary depending on the quality of the top coats specified. It is permitted to use acid catalysts from a source different to that of the top coat if approved by Materials Laboratory of Product Engineering and agreed by the respective vendors.
