PolySurF HP Methacrylate mono- and di- phosphate ester ADD APT Adhesion Promoters >> Phosphate Crosslinking / Coupling / Curing Agents >> Acrylates/ Methacylates Flame and Smoke Retardants >> Phosphorus based Acrylics/ Acrylates Polyesters ADHESIVE >> Radiation Curing (UV/EB) ADD APTâ PolySurF HP is a solvent free UV-curable additive. It can also act as a co-polymerisable anionic surfactant and/or adhesion promoter with flame retardant properties. It is a proprietary mixture of Acrylated mono-and di-Phosphate ester; where the reactive Acrylate group is Methacrylate.Easy to handle liquid It is an effective flame retardant, which does not contain halogens. Addition of approximately 4%, results in a final P content of the flame-retardant polyester or polyacrylate of approx. 0.5 %. It improves both the storage and mechanical stability of an emulsion system, whereas grit building and foam formation is minimised. No migration of the surfactant occurs after film formation Paints and lacquers based on emulsions containing this “build-in” anionic surfactant show improved wet-scrub resistance, improved adhesion to metal and high yellowing resistance even after enamel application The mono-phosphate ester can be reacted with emulsions containing polymers with 2 or more epoxy groups or with emulsions containing, for example, Glycidyl(Meth)acrylate. The di-phosphate ester affords some degree of crosslinking without gel formation. Solvent- and halogen-free proprietary mixture of methacrylate mono- and di-phosphate ester. Used as UV-curable additive, co-polymerisable anionic surfactant and/or adhesion promoter with flame retardant properties. Suitable for polyesters and polyacrylates.
