CURABLE FILM-FORMING COMPOSITION EXHIBITING IMPROVED YELLOWING RESISTANCE |
摘要 |
<p>A curable film-forming composition of 5 to 95 weight percent (based on the total resin solids weight in the composition) of a crosslinking agent; 5 to 95 weight percent ot a polymer containing functional groups reactive with the crosslinking agent; and 0.01 to 15 weight percent of at least one additive selected from a reaction product of phosporous acid and: at least one diepoxide; at least one diepoxide and at least one anhydride; at least one diepoxide and at least one anhydride, chain extended with at least one diol; at least one monoepoxide and at least one anhydride, chain extended with at least one diepoxide; and mixtures thereof. The additives in the composition prevent thermal oxidation, minimizing visual effects (i.e., yellowing). A multi-component composite coating includes a base coat and a top coat which may be derived from the above curable film-forming composition.</p> |
