| 摘要 | Provided herein are coating compositions comprising the reaction product of a tetra alkyoxyorthosilicate or a partially condensed oligomer thereof and a polyester resin containing hydroxyl groups. The coating compositions advantageously have a high solid content and/or low volatile organic content (VOC) in combination with a low viscosity. The coating compositions are capable of drying quickly, curing in ambient conditions and may be formulated in one-pack. | ||

| 主权项 | 1. An ambient curing coating composition comprising a reaction product of a tetra alkyoxyorthosilicate or a partially condensed oligomer thereof and a polyester resin containing hydroxyl groups, wherein (a) the polyester resin has a number average molecular weight of between about 1250 and about 4000, and a hydroxyl equivalent weight of between about 800 and about 4500, and (b) the ratio of alkoxy groups on the tetra alkyoxyorthosilicate to hydroxyl groups on the polyester resin containing hydroxyl groups is in the range of 2:1 to 40:1. | ||
