Polysurf HPF Methacylated mono- and di-phosphate ester ADD APT Crosslinking / Coupling / Curing Agents >> Acrylates/ Methacylates Surfactants >> Phosphate esters Acrylics/ Acrylates Polyesters ADHESIVE >> Radiation Curing (UV/EB) ADD APTâ PolySurF HPF is a solvent free UV-curable additive. It can also act as a polymerisable surface active agent with excellent wetting and levelling properties. It is a proprietary mixture of Acrylated mono-and di-Phosphate ester; where the reactive Acrylate group is Methacrylate, modified with O-(CF2 O)n.10-CH3Easy to handle liquid due to the low viscosity Already at low concentrations a reduced surface tension can be achieved thereby improving the wetting of difficult substrates like soiled metal and ‘plastics’. Surface tension of ADD APT PolySurF HPF in g/100g demineralized water Distilled water 72 mN/m 0.1 g PolySurF HPF 34 mN/m 0.2 g PolySurF HPF 29 mN/m ADD APT® PolySurF HPF can easily be co-polymerised with other acrylic monomers and Styrene. The di-phosphate ester affords some degree of crosslinking without gel formation. Solvent-free proprietary mixture of methacrylate mono- and di-phosphate ester. Used as UV-curable additive, polymerisable surfactant with excellent wetting and levelling properties. Suitable for polyesters and polyacrylates.
