Applications:

 Silane HENGDA-M7123 is a monomeric alkyalkoxysilane 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 solution.
 High-performance penetrating sealers: Premium-grade penetrating sealers are easily formulated by blending 10 to 40 percent HENGDA-M7123 in alcohols or organic solvents
 Long-lasting wear protection: Water repellency that lasts years on surface of highway bridge decks has been documented with alkyalkoxysilanes.
 Filler dispersion: HENGDA-M7123 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 HENGDA-M7123 treated minerals or pigments are incorporated into polymers e.g. PP, PE. Loading levels of 0.5 to 1.5 wt% HENGDA-M7123 based on the weight of minerals or pigments are typically recommended.
