 Silane HENGDA-M7033 is a monomeric alkylalkoxysilane that, when exposed to moisture, is reactive with the mineral. 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.
 High-Performance Penetrating Sealers.
Premium-grade penetrating sealers are easily formulated by blending 10 to 40 percent HENGDA-M7033 in alcohols or organic solvents.
 Sol-Gel system.
Propyltrimethoxysilane is an important component in Sol-Gel system.
 Filler Dispersion.
HENGDA-M7033 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 e.g. PP, PE. Loading levels of 0.5 to 1.5 wt% HENGDA-M7033 based on the weight of minerals or pigments are typically recommended.
