Synolite 9248-U-3 Unsaturated polyester based on DCPD DSM Polyester >> Unsaturated SEALANT >> Putty Synolite 9248-U-3 is an unsaturated polyester based on DCPD, dissolved in styrene. The resin is pre-accelerated with polymeric amines, has a medium viscosity, and a high reactivity. Synolite 9248-U-3 is a binder for highly filled knifing fillers and putties for use on metal, wood and mineral substrates, and a binder for chemical anchors. In putties for car refinishes, this resin may be applied as such, or as the rigid component ("booster") in blends with flexible resins. Synolite 9248-U-3 is cold-curing, even around 0°C. Putty made from Synolite 9248-U-3 gives rapid hardening of thick and thin layers, also at lower temperatures. The low viscosity of the resin promotes the wetting of the extenders, thus reducing the formulation time of fillers. Synolite 9248-U-3 fillers and putties give very good adhesion to various substrates, including mild steel, galvanized steel, aluminium, and polyester. Suitable extenders are talc, dolomite/calcite, crystalline chalk and barytes with a low iron content. Talc is applied as the main component because it improves sanding properties, and the adhesion to the substrate. In addition, the more spherical extenders such as dolomite, chalk and barites ensure dense packing. Unsaturated polyester based on DCPD pre-accelerated with polymeric amines. Used as a binder for highly filled putties on metal, wood and mineral substrates. Can be applied as such, or as the rigid component ("booster") in blends with flexible resins in putties for car refinishes. Possesses medium viscosity and high reactivity. Gives rapid hardening of thick and thin layers, also at lower temperatures and very good adhesion to various substrates, including mild steel, galvanized steel, aluminium, and polyester. Can be used in combination with extenders such as talc, dolomite/calcite, crystalline chalk and barytes with a low iron content.
