Name: Evonik Dynasylan HYDROSIL 1151 Aqueous 3-aminopropylsilane hydrolysate
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik Dynasylan HYDROSIL 1151 Aqueous 3-aminopropylsilane hydrolysate

Ready-to-use aqueous hydrolysate — no on-site acid catalysis or aging required.
Stable, low-viscosity solution with optimized silanol concentration for efficient surface bonding.
Contains reactive primary amino groups (–NH₂) and hydrolyzed silanol (Si–OH) functionalities for dual-mode coupling.
pH-stabilized formulation (pH ≈ 4.0–4.5) ensures shelf-life stability and compatibility with common water-based systems.
Low VOC and solvent-free — supports sustainable manufacturing and regulatory compliance (e.g., REACH, TSCA).

Typical Applications Of Evonik Dynasylan HYDROSIL 1151 Aqueous 3-aminopropylsilane hydrolysate

Surface modification of silica, glass, and metal oxides in mineral-filled composites and coatings.
Adhesion promotion in waterborne automotive primers and industrial maintenance coatings.
Functionalization of fillers (e.g., calcium carbonate, clay) for improved dispersion and polymer–filler interaction in thermoplastics and elastomers.
Pre-treatment agent for glass fiber sizing in reinforced plastics and pultrusion resins.
Coating additive for anti-corrosion pretreatments on steel and aluminum substrates.
