Profile: Shanghai Profirst Co., Ltd. specializes in providing organosilicon monomers and organic silicon coupling agents. We are an ISO 9001:2000 certified company. Organosilicon monomers include chloromethymethyldichlorosilane, phenyltriethoxysilance, methyltrimethoxysilane, benzyltrimethylsilane, dichlorolmethyltrichlorosilane, vinyltriethoxysilane and tetraethoxysilane. Our organic silicon coupling agents include anilinomethyltrimethoxysilane, chloromethyltriethoxysilane, dimethyldiethoxysilane, phenyltriethoxysilane and methylvinyldichlorosilane. Tetraethoxysilane is a colorless and hyaloid liquid. I It is slightly soluble in benzene, and there is no mechanical admixture in the product. Tetraethoxysilane can be easily hydrolyzed into colloid polymer of silicon dioxide and alcohol. It can absorb water in the damp air and become turbid.
