LS-O110 Aqueous 3-aminopropylsilane Hydrolysate

Silfluo LS-O110 is an aqueous 3-aminopropylsilane hydrolysate, an amino-functional siloxane oligomer supplied as a water-based solution.

The product is fully pre-hydrolyzed; no alcohol byproduct is released during formulation or application.

The amino-functional siloxane oligomer provides reactive amine groups for bonding to organic polymer matrices and siloxane groups for condensation with hydroxylated inorganic surfaces.

The oligomeric siloxane backbone forms a denser interfacial crosslinked layer compared with monomeric aminosilane under equivalent conditions.

Used as VOC-free adhesion promoter and coupling agent in waterborne coatings, fiberglass sizing, mineral binders, foundry resins, and aqueous sealant systems.

Performance equivalent to Evonik Dynasylan HYDROSIL 1151.
