    Abstract: Two-part, elastomeric sealant coatings curable at ambient temperature. The sealant contains a radical polymerizable component, an oxidizing agent and a reducing agent, and optionally an epoxy component, polar wax, and/or rheology modifier. The radical-polymerizable component contains 25 to 45 weight percent of alkacrylate monomer and unsaturated phosphorous monomer and 55 to 75 weight percent of an ethylenic unsaturated liquid elastomer polymer having a number average MW of from 3,000 to 9,500 and a backbone T9 less than-30 °C. The elastomer polymer makes up 32 to 55 weight percent of the sealant and epoxy component makes up 2 to 15 weight percent. The elastomeric sealant coatings provide corrosion protection over the seams and maintain a crack-free surface over a broad temperature range. The sealant coatings are useful for applying over seams of joined metal parts, especially weld seams in the manufacture of automotive unit bodies, doors, floors, hoods, trunks, and trunk lids.

    Abstract translation: 两部分弹性密封剂涂料可在环境温度下固化。 密封剂包含可自由基聚合的组分,氧化剂和还原剂,以及任选的环氧组分,极性蜡和/或流变改性剂。 可自由基聚合的组分包含25至45重量%的烷基丙烯酸酯单体和不饱和磷单体,55至75重量%的数均分子量为3,000至9,500的乙烯不饱和液体弹性体聚合物和主链T9小于-30° C。 弹性体聚合物占密封剂的32至55重量%,环氧树脂组分占2至15重量%。 弹性密封剂涂层在接缝上提供防腐蚀保护,并在宽温度范围内保持无裂纹的表面。 密封剂涂层可用于在接合的金属部件,特别是汽车单元体,门,地板,罩,树干和树干盖的制造中应用接缝。
