Name: Evonik Dynasylan HYDROSIL 2627 Water-borne amino-functional and alkyl-functional silane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik Dynasylan HYDROSIL 2627 Water-borne amino-functional and alkyl-functional silane

Water-based, VOC-compliant formulation enabling sustainable surface modification without organic solvents.
Dual functionality: primary amino groups for covalent bonding with polymers and substrates; alkyl chains for hydrophobicity and compatibility enhancement.
Excellent colloidal stability in aqueous systems across a broad pH range (pH 3–8), supporting easy integration into waterborne coatings and adhesives.
Enables strong interfacial adhesion between inorganic fillers (e.g., silica, glass, metals) and organic matrices in composite formulations.
Reduces moisture sensitivity of cured films while maintaining good film flexibility and chemical resistance.

Typical Applications Of Evonik Dynasylan HYDROSIL 2627 Water-borne amino-functional and alkyl-functional silane

Waterborne automotive primers and clearcoats for improved pigment dispersion and substrate adhesion.
High-performance architectural coatings requiring enhanced durability, stain resistance, and alkali stability on concrete and masonry.
Adhesives and sealants for bonding glass, aluminum, and treated plastics in construction and transportation.
Functional additives in mineral-filled polymer composites (e.g., PVC, PU, epoxy) to improve filler-matrix coupling and mechanical performance.
