Method for improving adhesion of durable coatings to weathered substrates and coatings made therefrom |
摘要 |
A latex binder suitable for producing high gloss coating on weathered substrates and a method for producing such coatings. The binder includes a low molecular weight and low acid number latex polymer having an acid functional and an enamine functional moiety that results from the reaction of ammonia or amine with an acetoacetyl functional pendant moiety on the latex polymer. A film containing the latex binder is applied on a substrate and then exposed to ambient light and air to produce a high gloss highly adherent film on difficult to adhere surfaces, such as weathered chalky substrates. |
