Silane modified polyether sealant, also known as silicone modified polyether sealant and silalkyl terminated polyether sealant, is a kind of high-performance environmental protection sealant based on silane terminated polyether (polyether as the main chain and siloxane as the end). Because of its advantages and advantages of silicone sealant and polyurethane sealant, it has shown excellent weather resistance, durability, high deformation resistance, good adhesion, painting, environmental friendliness, low stain, low viscosity and excellent workability. It has been paid more and more attention by the domestic construction industry, while in the industrial fields such as automobile manufacturing, rail transit, and integrated transportation Packing manufacturing, equipment manufacturing, electronic and electrical fields are also getting more and more promotion and application.


Let's first look at the performance comparison of silane modified polyether sealant, silicone sealant and polyurethane sealant:

The good comprehensive properties of silane modified polyether adhesive are closely related to the special structure of its basic polymer (silyl terminated polyether).


Let's talk about some outstanding features of silane modified polyether adhesive:
1. The universality of bonding to the base material. Due to the low surface energy and high permeability of the basic polymer (silyl terminated polyether), it has good wetting ability for most inorganic, metal and plastic substrates, so it can produce good adhesion to the substrate.
