Dynasylan® HYDROSIL 2926

Dynasylan® HYDROSIL 2926 is an aqueous oligomeric diol-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 2926 is a colorless to slightly yellowish aqueous solution, miscible with alcohols or water. Dynasylan® HYDROSIL 2926 is a bifunctional organic compound in which the functional silanol groups can be bonded to an inorganic substrate; the organophilic diol-functional group can interact with a suitable polymer. The particular advantage of Dynasylan® HYDROSIL 2926 compared with the corresponding epoxyfunctional 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 2926 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.
