SCA-K03M N-Propyltrimethoxysilane (CAS No. 1067-25-0) CAS NO.1067-25-0

N-Propyltrimethoxysilane (CAS No. 1067-25-0), silane coupling agent SCA-K03M, is a monomeric alkylalkoxysilane that, when exposed to moisture, is reactive with the minerals. The monomer can penetrate deeply into a substrate, and then react to form a protective surface surrounding each microscopic particle. This protective surface is extremely durable and leads to significant improvements in weather resistance. The silane is easy to dissolve in organic solvents to form clear, colorless, stable solutions.

1. High-Performance Penetrating Sealers: Premium-grade penetrating sealers are easily formulated by blending 10 to 40 percent SCA-K03M in alcohols or organic solvents.

2. Sol-Gel system: n-Propyltrimethoxysilane is an important component in Sol-Gel system.

3. Filler Dispersion: SCA-K03M can be used as a surface modifier to generate hydrophobicity (e.g. mineral fillers or inorganic pigments). The medium-chain alkyl functionality in unique compound properties when SCA-K03M treated minerals or pigments are incorporated into polymers e.g. PP, PE. Loading levels of 0.5 to 1.5 wt% SCA-K03M based on the weight of minerals or pigments are typically recommended.  
 

Abstract
N-Propyltrimethoxysilane (CAS No. 1067-25-0), silane coupling agent SCA-K03M, is a monomeric alkylalkoxysilane that, when exposed to moisture, is reactive with the minerals. The monomer can penetrate deeply into a substrate, then react to form a protective surface surrounding each microscopic particle. This protective surface is extremely durable leads to significant improvements in weather resistance. The silane is easy to dissolve inganic solvents to form clear, colorless, stable solutions.

Application
N-Propyltrimethoxysilane (CAS No. 1067-25-0), silane coupling agent SCA-K03M, is an important additive fmany applications. Examples are:
1. High-Performance Penetrating Sealers: Premium-grade penetrating sealers are easily formulated by blending 10 to 40 percent SCA-K03M in alcoholsganic solvents.
2. Sol-Gel system: N-Propyltrimethoxysilane is an important component in Sol-Gel system.
3. Filler Dispersion: SCA-K03M 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 KH-331 treated minerals pigments are incorporated into polymers e. G. PP, PE. Loading levels of 0.5 to 1.5 wt% SCA-K03M based on the weight of minerals pigments are typically recommended.
