Dynasylan® HYDROSIL 1151

Dynasylan® HYDROSIL 1151 is an aqueous oligomeric amino-functional silane hydrolysate, which acts as an adhesion promoter between inorganic materials (for example glass, metals and fillers) and organic polymers (thermosets, thermoplastics and elastomers). Dynasylan® HYDROSIL 1151 is a colorless to slightly yellowish aqueous solution with an amine-like odour, miscible with alcohols or water. Dynasylan® HYDROSIL 1151 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 nonflammability, the fact that no volatile organic constituents are released and the fact that no particular equipment safety precautions are necessary. Dynasylan® HYDROSIL 1151 can be diluted with water in all proportions. The hydrolysates are long-term stable. Examples of suitable inorganic substrates are glass, glass fibres, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite and mica; also suitable are aluminium trihydroxide, kaolin, talc, other silicate fillers, metal oxides and metals. Examples of particularly suitable polymers are epoxy resins, polyurethanes, phenolic resins, furane resins, melamine resins, PA, PBT, PC, EVA, PP, PVAC, acrylates and silicone.
