Abstract：
SCA-K12M 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.
Applications and Performance：
1. High-Performance Penetrating Sealers: Premium-grade penetrating sealers are easily formulated by blending 10 to 40 percent SCA-K12M in alcohols or organic solvents.
2. Long-Lasting Wear Protection: Water repellency that lasts years on surface of highway bridge decks has been documented with alkyalkoxysilanes.
3. Filler Dispersion: SCA-K12M 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-K12M treated minerals or pigments are incorporated into polymers e.g. PP, PE. Loading levels of 0.5 to 1.5 wt% SCA-K12M based on the weight of minerals or pigments are typically recommended.
