Structural silicone resin why there are bars in some solvent traces (some sticky and extent)

Silicone resins are highly cross-linked network structure of the polyorganosiloxane, usually with methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, diphenyldichlorosilane or methylbenzene various mixtures based dichlorosilane, in the presence of an organic solvent such as toluene, at a lower temperature hydrolysis to give the acid hydrolyzate. The initial product of the hydrolysis of cyclic, linear and crosslinked polymer mixture, usually contain a considerable number of hydroxyl groups. Hydrolysis was washed with water to remove the acid, neutral initial polycondensation thermal oxidation in the air or in the presence of a catalyst, etc. into Ding Chuan rough satin NAO stubble advised long slide polycondensation step, and finally the formation of three-dimensional network structure highly crosslinked. And you said it should be the beginning of the initial hydrolysis product. .
