SMPs are the main components in solvent-free and isocyanate-free sealant and adhesive products.〔Jeffrey D. Umpleby "Polymer composition" U.S. Patent 4574133. 1986.〕 Typically the sealant products manufactured with silyl modified polymers have good adhesion on a wide range of substrate materials, and have good temperature and UV resistance. ==Curing process== The products cure from a liquid or gel state to a solid. Curing entails crosslinking by the hydrolysis of silyl ethers: :RSi(OCH3)2R' + H2O → ()2O + 2 CH3OH This hydrolysis generates siloxane linkages. A catalyst is required for this condensation process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Silyl modified polymers」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
