.~ Plural film forming coatings wherein one coating contains a chemical treating agent for the other
DEFINITION
Classification: 427/333
(under subclass 331) Processes in which a treating agent, such as a solvent, reactant, hardened or catalyst for one coating is applied as part of a contiguous film forming coating so that plural coatings are formed.
(1) Note. The mere cooperative effect produced by two coatings, such as better corrosion resistance, etc., is not considered treatment for the purposes of this subclass. One of the film forming coatings has to cause a change to take place in the other film forming coating for placement in this subclass.
(2) Note. The temperature of one coating affecting another coating is not considered enough for placement in this subclass.
