    • A mixture comprising epoxidized liquid rubbers, amine hardeners and sulfur applied to a metal and cured produces a coating that is highly durable and provides strong anticorrosive protection to the metal. The amine hardeners serve to activate and dissolve the sulfur, speed up the curing time, and also bond to the rubbers to create a continuous molecular matrix. The activated sulfur also links the rubber molecules together, as well as anchoring the polymer matrix to the metal substrate via chemical bonds. In a preferred embodiment, the formulation also includes two types of accelerators which act synergistically to further reduce the curing time to less than one hour. The addition of micronized aluminum oxides provides increased uniformity of heating during curing and results in a more uniform coating. The addition of calcium oxide together with the presence of amines and aluminum oxide provides a complete absorption of acidic gases produced during curing. The addition of high molecular butadiene nitrile rubber increases the coatings impact resistance, low-temperature flexibility, and adhesion.
    • 包含环氧化液体橡胶,胺硬化剂和施加到金属上的硫并且固化的混合物产生高度耐用的涂层,并为金属提供强烈的防腐蚀保护。 胺固化剂用于活化和溶解硫,加速固化时间,并且还结合到橡胶上以产生连续的分子基质。 活化的硫还将橡胶分子连接在一起,以及通过化学键将聚合物基质锚定到金属基底上。 在优选的实施方案中,制剂还包括两种类型的促进剂,其协同作用以进一步将固化时间减少至少于1小时。 添加微粉化的氧化铝在固化期间提供加热的均匀性,并且导致更均匀的涂层。 加入氧化钙以及胺和氧化铝的存在提供了在固化期间产生的酸性气体的完全吸收。 添加高分子丁二烯丁腈橡胶增加了涂料的耐冲击性,低温柔韧性和粘附性。
