Vinyltriethoxysilane

Silane USi-402

Vinyl functional alkoxysilane

Product Description

Chemical Name: Vinyltriethoxysilane

Synonym: Ethenyltriethyloxy-silane;

CAS NO.: 78-08-0

EINECS NO.: 201-081-7

Molecular weight： 190.31

Properties

USi-402, as a co-monomer in polymers, can much improved wet scrub resistance andabrasion resistance thanks to crosslinking and better adhesion to the substrate. Silane-modified thermoplastics obtained by grafting

with USi-402 can be processed further using standard techniques. On exposure to moisture, the silyl groups condense and function as crosslinking or adhesion points.

By treating fillers with USi-402, mineral filledpolymers can be obtained which exhibitimproved mechanical and electrical properties.

In addition, the particles are rendered strongly water repellent, which results in improved filler dispersibility and thus facilitates processing.Organic surface coatings will adhere more strongly to inorganic substrates that have

been treated with USi-402. As a result, these coatings demonstrate markedly greater scratch resistance and resistance to chemicals.
