Advanced Polymer · AP-Silane

AP-Silane 90 is a high-purity methyltrimethoxysilane coupling agent designed to impart durable hydrophobicity to inorganic materials. Upon exposure to atmospheric moisture, it reacts to form a long-lasting sealant layer that preserves the natural appearance of the treated substrate. Widely used in water-repellent and protective surface treatments, AP-Silane 90 improves durability and moisture resistance across a variety of industrial and architectural applications.
