Dynasylan® 40 is formed in the presence of water from tetraethyl silicate (Si[OEt]4) by partial hydrolysis of the ethoxy groups to hydroxyl groups and subsequent condensation with formation of siloxane bonds (-Si-O-Si-). Dynasylan® 40 is a colorless, low-viscosity liquid with an SiO2 content of 40% (the Si content of Dynasylan® 40 is calculated as SiO2). The polysilicic acids still have a sufficient content of ethoxy groups which can be activated by acid- or base-catalyzed hydrolysis. Condensation starts even during hydrolysis, with the formation of relatively large polymeric molecules. During storage of these hydrolysates, condensation continues until a gel is formed, where the rate depends on the degree of hydrolysis. The action of the hydrolysates as binders is based on the continuation of the hydrolysis with subsequent gelation and dehydration to give polymeric SiO2 structures. voir moins | |

Dynasylan® 2201 EQ is a 50% solution of silane in methanol, is a colorless liquid with an alcohol-like odor and is soluble in alcohols, ketones, esters or aromatic hydrocarbons. Due to novel patented process, Dynasylan® 2201 EQ is the first ureidofunctional silane, which contains no carcinogenic by-products, e.g. ethylcarbamate. Dynasylan® 2201 EQ is therefore not classified as "carcinogenic, class 2". voir moins | |
