    • PURPOSE: Provided is an autodepositable coating composition that is resistant to surface defects, including cratering, edge pullback, and defects caused by the presence of particulate matter. CONSTITUTION: The autodepositable composition comprises (a) water and (b) a reactive prepolymer comprising a reaction product of (i) a resin containing at least one epoxy group and at least one hydroxyl group reactive with a free isocyanate group at a first temperature and (ii) a hybrid crosslinking agent containing both at least two free isocyanate groups capable of reacting with the resin at the first temperature and at least one functional group capable of reacting with the resin only at a second temperature higher than the first temperature, wherein the reactive prepolymer contains in unreacted form at least one of the functional groups capable of reacting with the resin only at the second temperature.
    • 目的:提供一种抗表面缺陷的自动沉积涂料组合物,包括发泡,边缘回缩和由颗粒物质的存在引起的缺陷。 构成:可自动沉积的组合物包含(a)水和(b)反应性预聚物,其包含在(i)含有至少一个环氧基的树脂和至少一个在第一温度下与游离异氰酸酯基反应的羟基的反应产物,和 (ii)混合交联剂,其含有能够在第一温度下能够与树脂反应的至少两种游离异氰酸酯基团和至少一种能够仅在高于第一温度的第二温度下与树脂反应的官能团,其中, 反应性预聚物以未反应形式包含仅在第二温度下能够与树脂反应的至少一个官能团。
