Polysurf HPH Methacrylated mono- and di-phosphate ester ADD APT Crosslinking / Coupling / Curing Agents >> Acrylates/ Methacylates Plasticizers >> Phosphate Surfactants >> Phosphate esters Acrylics/ Acrylates Polyesters Polyvinyl Chloride (PVC) ADHESIVE >> Radiation Curing (UV/EB) ADD APTâ PolySurF HPH is a solvent-free UV-curable additive. It can also act as physical properties a polymerisable hydrophilic non-ionic surfactant and/or co-polymerisable plasticizer. It is a proprietary mixture of Acrylated mono- and di-Phosphate ester; the mono-Phosphate ester being O-(EO)n>10-CH3 modified; where the reactive Acrylate group is Methacrylate Easy to handle liquid It imparts excellent Levelling/Wetting and improves adhesion to metal surfaces in UV-curable systems. It effectively improves the wetting of substrates like wood and metal as a monomer but also when incorporated in an emulsion. It improves both the storage and mechanical stability of an emulsion system, whereas grit building and foam formation is minimised. No migration of the non-ionic surfactant occurs after film formation Paints and lacquers based on emulsions containing this “build-in” hydrophilic non-ionic surfactant show improved wet-scrub resistance, improved adhesion to metal and high yellowing resistance even after enamel application. It has flame retardant properties and does not contain halogens. 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, polymerizable hydrophilic non-ionic surfactant and/or co-polymerizable plasticizer. Suitable for polyesters, polyacrylates and polyvinylchlorides.
