Applications
Ureido-functional silane has better stability than aminosilanes in reactive polymer systems, like phenolic, epoxy, urea-melamine or polyurethane. Ureido-functional silane does not generate color with time and aging. Ureido-functional silane provides nitrogen reactivity without typical aminosilanes strong basic characteristics.Ureido-functional silane has good adhesive and sealant adhesion to oil metals. SiSiB® PC2510 can improve adhesion between the inorganic filler or fiber and the polymer. SiSiB® PC2510 can be used for glass fiber sizes and finishes, wool insulation resin binders, numerousprimers, foundry sand binders, adhesives, sealants and abrasive grinding wheel binders.
Packing
200L steel drum or on request.
Storage
Stored in a cool, dry place. Avoid light.
