Dynasylan® HYDROSIL 1151

Technical Datasheet | Supplied by Evonik
Dynasylan® HYDROSIL 1151 by Evonik is an aqueous 3-aminopropylsilane hydrolysate. Acts as an adhesion promoter. Provides improved mechanical properties, such as flexural strength, tensile strength, impact strength and modulus of elasticity. Can also improve processing properties such as adhesion, better filler dispersion and high flash point. It is a bifunctional organic compound in which the functional silanol groups can be bonded to an inorganic substrate; the organophilic amino group can interact with a suitable polymer. The particular advantage of Dynasylan® HYDROSIL 1151 compared with the corresponding aminofunctional alkoxysilanes is its non-flammability, the fact that no volatile organic constituents are released and the fact that no particular equipment safety precautions are necessary. It can be diluted with water in all proportions. The hydrolysates are long term stable.
