    • Improved coating compositions which incorporate acrylate resins having multiple carbon-to-carbon bond unsaturation attached to the polymer chain through ester and/or urethane linkage are derived from the reaction product of:(1) an acrylate resin having multiple epoxide functionality attached to the polymer chain through an ester or ether linkage reacted with an unsaturated carboxylic acid preferably acrylic or methacrylic acid; or(2) an acrylate resin having multiple hydroxyl group functionality reacted with an organoisocyanate having 0.5 to 1.0 unit of carbon-to-carbon unsaturation per mole of isocyanate.Such coatings are particularly useful in formulating gel coat composites which exhibit hydrolytic stability and good weatherability.
    • 具有通过酯和/或氨基甲酸酯键连接到聚合物链上的具有多个碳 - 碳键不饱和键的丙烯酸酯树脂的改进的涂料组合物衍生自以下的反应产物:(1)具有连接到聚合物上的多个环氧官能团的丙烯酸酯树脂 链通过与不饱和羧酸优选丙烯酸或甲基丙烯酸反应的酯或醚键; 或(2)具有多个羟基官能团的丙烯酸酯树脂与每摩尔异氰酸酯具有0.5至1.0单位碳 - 碳不饱和度的有机异氰酸酯反应。 这种涂层特别可用于配制表现出水解稳定性和良好耐候性的凝胶涂层复合材料。

    • An improved hydroxyl functional urethane-extended polyester is based on the condensation reaction of fumaric acid, one or more non-aromatic polyols, azelaic acid and optionally one or more non-aromatic carboxylic acids including lauric acid or stearic acid. The hydroxylated polyester urethane oligomer possesses a molecular weight below 2600 and a mole ratio of hydroxyl groups to urethane linkage of from 0.5 to 6. Gel coats prepared from these oligomers exhibit superior water resistance and improved weathering characteristics.
    • 改进的羟基官能聚氨酯延伸的聚酯基于富马酸,一种或多种非芳族多元醇,壬二酸和任选的一种或多种非芳族羧酸(包括月桂酸或硬脂酸)的缩合反应。 羟基化聚酯氨基甲酸酯低聚物的分子量低于2600,羟基与氨基甲酸酯键的摩尔比为0.5至6.由这些低聚物制备的凝胶涂层显示出优异的耐水性和改善的耐候性。
