产品描述

一、STP树脂简介

Brief introduction of STP resin

 

端硅烷基聚醚预聚体,即以PPG聚醚为主链、硅氧烷基封端的高分子聚合物,即硅烷改性聚醚(silane terminated polyether polymer),简称STP树脂,又叫MS树脂。硅烷改性聚醚的特征结构是主链为大分子聚醚,端基是含有可水解基团的硅氧烷,兼具聚氨酯密封胶和硅酮密封胶的结构优点;其固化机理是在催化剂作用下,端基硅氧烷与空气中的水份反应生成端基硅醇,硅醇与硅醇之间交联反应形成具有弹性的网状结构,实现由液体到固体的固化过程。

End Silicon alkyl polyether prepolymer, namely PPG Polyether mainly chain, silicon oxygen alkyl end polymer, namely Silane modified Polyether, referred to as STP resin, also known as MS Resin. The characteristic structure of silane modified Polyether is the main chain is macromolecular Polyether, the end-base is the siloxane containing the hydrolyzed group, which has the structural advantages of both polyurethane sealant and silicone sealant, and the curing mechanism is that the end-base siloxane reacts with the moisture in the air to produce the end-base silicone alcohol under the action of the catalyst. The cross-linking reaction between silicone alcohol and silicone alcohol forms a flexible network structure, which realizes the solidification process from liquid to solid.
