Coating adhesion promoter

Coating adhesion promoter is a kind of special resin modified with silane coupling agent, the appearance is light yellow transparent liquid, not only for general metal surface (tin, steel, cast iron, aluminum alloy, electroplating) has an excellent effect of trivial, but for some special metal surface (e.g., copper), has a very good the effect, can improve the ductility of coating film and impact resistance, high temperature rapid baking, coating film with excellent weatherability.
The performance characteristics of coating adhesion promoter is as follows:
1) coating adhesion promoter is an exclusively for paint primer or one-time coating paint using the paint additives, to improve on the surface of metal as a sex, for some difficult adhesion of metal, also can provide good adhesion;
(2) the coating with adhesion promoter can improve coating on the surface of metal as a sex, so as to improve the ductility of coating film and the resistance to impact, and the adhesion between the layers of the coating has excellent effect;
(3) coating with adhesion promoter shall not affect the coating of storage and the weatherability of the coating;
(4) coating with adhesion promoter can be resistant to more than 280 ℃ high temperature baking, high temperature baking discoloration rapidly.
