CAS NO.: 1067-53-4

EINECS NO.: 213-934-0

Molecular weight： 280.39

Properties

Silane USi-412 acts as an adhesion promoter for various mineral-filled polymers improving their mechanical and

electrical properties, especially after exposure to moisture. Once bonded to an inorganic filler.

Silane USi-412 hydrophobises the filler surface. This effect improves the compatibility of fillers with the polymer

matrix, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.

Polymer dispersion, modified with silane USi-412 show improved adhesion strength in wet conditions and wet scrub resistance.
