Name: Evonik Dynasylan AR Hydrolyzable polyethyl silicate
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik Dynasylan AR Hydrolyzable polyethyl silicate

Hydrolyzable ethyl silicate structure enables controlled in-situ silica network formation under mild acidic or neutral conditions.
High purity and low chloride content ensure compatibility with sensitive catalysts and metal substrates.
Excellent hydrolytic stability in sealed, anhydrous storage—extends shelf life without premature condensation.
Reactive silanol groups provide strong covalent bonding to hydroxylated surfaces (e.g., glass, metals, minerals).
Tailored molecular weight distribution supports balanced reactivity and film-forming performance in sol-gel coatings.

Typical Applications Of Evonik Dynasylan AR Hydrolyzable polyethyl silicate

Anti-corrosion primers for aluminum, steel, and magnesium alloys in automotive and aerospace components.
Hybrid sol-gel binders in high-performance ceramic and refractory coatings.
Surface modification agents for silica-based nanocomposites and functional fillers.
Adhesion promoters in UV- and thermally curable hybrid organic-inorganic coatings.
Consolidation agents for porous mineral substrates such as sandstone and limestone in conservation technology.
