产品介绍
双组份聚氨酯防水涂料属于双组份化学反应固化型防水材料，其中甲组份是由聚醚和异氰酸酯缩聚得到的异氰酸酯封端的预聚体，乙组分是由增塑剂、固化剂、增稠剂、促凝剂、填充剂组成的彩色液体。使用时将甲、乙两组份按比例混合均匀 , 涂刷在防水基层表面上，经常温交联固化，形成橡胶状弹性涂膜，从而起到防水作用。
Two component polyurethane waterproof coating belongs to the category of two-component chemical reaction curing waterproof materials. Component A is a prepolymer with isocyanate end caps obtained by the condensation of polyether and isocyanate, while component B is a colored liquid composed of plasticizers, curing agents, thickeners, accelerators, and fillers. When in use, mix the two components A and B evenly in proportion, apply them on the surface of the waterproof base layer, and frequently crosslink and solidify at high temperatures to form a rubber like elastic coating, thus playing a waterproof role.
