Abstract
N-Propyltriethoxysilane (CAS No. 2550-02-9), silane coupling agent SCA-K03E, 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.

Application
N-Propyltriethoxysilane (CAS No. 2550-02-9), silane coupling agent SCA-K03E, is an important additive for many applications. Examples are:
1. High-Performance Penetrating Sealers: Premium-grade penetrating sealers are easily formulated by blending 10 to 40 percent SCA-KO3E in alcohols or organic solvents.
2. Sol-Gel system: N-Propyltrimethoxysilane is an important component in Sol-Gel system.
3. Filler Dispersion: SCA-KO3E 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-KO3E treated minerals or pigments are incorporated into polymers e. G. PP, PE. Loading levels of 0.5 to 1.5 wt% SCA-KO3E based on the weight of minerals or pigments are typically recommended.
