Methyltrimethoxysilane (MTMS)Methyltrimethoxysilane an alkyltrialkoxysilane is an important component in sol-gel systems. It is a colourless, low-viscosity liquid. It is regarded as trifunctional since all three alkoxy groups are able to hydrolyse. Additionally, it contains a methyl group that adds organic character to the products.In some sol-gel applications it is partially hydrolysed to form a pre-product that can be further crosslinked using temperature.The equivalent grade of the product of different brands is D-20, GX-173, MTMS, Silsquest A-1630, Dowsil Z-6366, KBM-13, Silan-M1.
N-Octyltriethoxysilaneis a clear colourless liquid and soluble in common non-polar organic solvents (e.g. petroleum ether, toluene). However, its low volatility and viscosity makesit an easy-to-handle additive. During the hydrolysis reaction between water andN-Octyltriethoxysilane a certain amount of ethanol (VOC) is released.The equivalent grade of the product of different brands is BOSIL-294, GX-137, OCTEO, Silsquest A-137, Xiameter OFS-6341, KBE-3083, Silres-BS1601.
N-Propyltriethoxysilane is an alkyl alkoxysilane. It is a colourless, low viscosity liquid. It has an n-propyl organic group and a triethoxysilyl inorganic group. It provides a hydrophobic surface treatment.It is mainly used as construction waterproofing agent/protective agent, inorganic filler surface treatment agent, and pigment dispersant.The equivalent grade of the product of different brands is D-24, PTEO, DowsilZ-6264, KBE-3033.
