摘要:
Fabrics are disclosed having a coating comprising a reaction product of a silicone component derived from an aqueous silicone emulsion and a polyurethane component derived from an aqueous silicone dispersion. The fabrics are particularly useful in the preparation of airbags having improved air or gas retention properties.

A coated silicone rubber article comprising a silicone rubber substrate having a cured polyisobutylene coating on a surface thereof; and a method of preparing a coated silicone rubber article, comprising the steps of (a) applying a curable polyisobutylene composition to a surface of a silicone rubber substrate; and (b) curing the polyisobutylene composition.
摘要:
There is disclosed a stable, one-part moisture-curable composition containing: (A) 100 parts by weight of a saturated hydrocarbon polymer having on average more than 2 hydrolyzable silyl groups in its molecule; (B) 10 to 300 parts by weight of a silicon-free conduit compound having at least one C6 to C30 hydrocarbon group in its molecule, said compound being selected from the group consisting of (i) esters, (ii) ethers, (iii) epoxy-containing compounds, (iv) anhydrides and (v) ketones; and (C) a sufficient amount of a silanol condensation catalyst to cure said composition upon exposure to moisture.
摘要:
A novel saccharide siloxane copolymer is useful in personal care compositions. The saccharide siloxane copolymer may be used as a universal emulsifier to prepare low odor emulsions for personal care applications.
