New silanes containing at least two oxazolidinic moieties can be defined by means of the general formula:
wherein X₁, X₂, X₃ and X₄ have the meaning as reported in the specification, and each one of A₁, A₂ and A₃ represents from 0 to a plurality of siloxane radicals
-SiO-
and are better defined in the text of the specification.
These compounds are useful as crosslinking agents for moisture-hardening systems based on polyisocyanates, of acrylate polymers and of polyepoxides in compositions for coatings, sealants and adhesive agents.
含有至少两个
噁唑烷基的新型
硅烷可以通式定义:
其中X₁、X₂、X₃和X₄的含义如说明书所述,A₁、A₂和A₃中的每一个代表0至多个
硅氧烷基团
