The present invention provides an ambient temperature curable coating and coated articles therefrom in a rubbery, high elongation, weatherable coating composition which can be applied to flexible elastomeric substrates for a variety of purposes. Depending on the film forming polymer used in the composition, it may be used to provide resistance to ozone, oils and solvents, or the coating may be applied for the purposes of enhancing the cosmetic appearance of the substrate rubber. The curable coating mixture is a mixture of two parts, one part containing a solution of a functional film forming polymer, and the other part providing the curing component. The stability as a premixed, one-part solution is limited to up to several months. The curable film former and curing component are mixed together at an overall 4% to 25% solids content. The viscosity is less than 20,000 cps (Brookfield) such that the coating can be sprayed, brushed or dipped to form thin coatings of from 0.001-0.020 mils.
本发明提供了一种常温固化涂层及其涂覆制品,它是一种橡胶状、高伸长率、耐候性涂层组合物,可应用于柔性弹性基材,具有多种用途。根据组合物中所用成膜
聚合物的不同,该组合物可用于耐
臭氧、耐油和耐溶剂,也可用于提高基底橡胶的外观效果。可固化涂层混合物由两部分组成,一部分含有功能性成膜
聚合物溶液,另一部分提供固化成分。作为预混合的单组分溶液,其稳定性最长可达几个月。固化成膜剂和固化成分混合在一起,固体含量为 4%-25%。粘度小于 20,000 cps(Brookfield 值),可以喷涂、刷涂或浸渍,形成 0.001-0.020 密耳的薄涂层。
