SiSiB® PC1653

Synonym: [(Methyldiethoxysilyl)methyl]aminocyclohexane;

Countertype of Wacker GENIOSIL XL 924

Chemical Structure


SiSiB® PC1653 is a bifunctional organosilane possessing reactive amino groups and hydrolyzable inorganic ethoxysilyl groups. The dual nature of its reactivity allows SiSiB® PC1653 to bind chemically to both inorganic materials and organic polymers, thus functioning as an adhesion promoter, surface modifier and as a reactant for product modification.
SiSiB® PC1653 is a novel alpha silane. The close proximity of the nitrogen atom to the silicon atom can accelerate hydrolysis reaction compared to (amino-propyl)silanes.

SiSiB® PC1653 can be used in the production of silyl modified polymers which serve as binders in adhesives and sealants.
SiSiB® PC1653 also can be used as a crosslinker, water scavenger and adhesion promoter in silane-crosslinking formulations, such as adhesives, sealants and coatings.
SiSiB® PC1653 can be used as surface modifier for fillers (like glass, metal oxides, aluminum hydroxide, kaolin, wollastonite, mica) and pigments.
