MOISTURE CURABLE POLYMER SYSTEMS BASED ON A MIXTURE OF POLYSILYLATED POLYETHERS |
摘要 |
Low viscosity mixtures of polysilylated polyethers are described. The mixtures include a) 50 to 95 weight percent of one or more first polysilylated polyethers which are free of urea groups, have an average of two or more terminal hydrolysable silyl groups per molecule and have a molecular weight of 4,000 to 20,000 and 50 to 5 weight percent of one or more second polysilylated polyethers which are free of urea groups, have an average of 1.8 to 4 terminal hydrolysable silyl groups per molecule and have a molecular weight of 1000 to less than 400. The mixtures have surprisingly low viscosities, and are useful as curable components of adhesive, sealant, caulking and/or coating compositions. |
