Silane Coupling Agent Methyltrimethoxysilane (CAS No 1185-55-3) CAS NO.1185-55-3

abstract
silinktm sca-k01m silane is a monomeric alkylalkoxysilane with the shortest alkyl group that, when exposed to moisture, is an important component in sol-gel systems.
silinktm sca-k01m is a colorless, low-viscosity liquid. use requires acid- alkali-catalysed hydrolysis. silinktm sca-k01m is regarded as trifunctional since all three alkoxy groups are able to participate in this reaction. additionally silinktm sca-k01m contains a methyl group that addsganicacter to the products. hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (-si-o-si-).

application
1. high-performance penetrating sealers: premium-grade penetrating sealers are easily formulated by blending 10 to 40 percent sca-k01m in alcoholsganic solvents.
2. sol-gel system: it is an important component in sol-gel system.
3. filler dispersion: sca-k01m can be used as a surface modifier to generate hydrophobicity (e. g. mineral fillers inorganic pigments). the medium-chain alkyl functionality in unique compound properties when sca-k01m treated minerals pigments are incorporated into polymers e. g. pp, pe. loading levels of 0.5 to 1.5 wt% sca-k01m based on the weight of minerals pigments are typically recommended.
