ADD APT PolySurF HPH Mixture of acrylated mono-and di-phosphate ester ADD APT Photoinitiator Plasticizer >> Phosphate Acrylic/Acrylate Resins Polyester Vinyl Coatings >> UV / Radiation Curing ADD APT PolySurF HPH is a solvent-free UV-curable additive. It can also act as 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 Emulsions for paints, lacquers, printing inks and adhesives As surfactant: 0.5 - 2.5 % wt. based on monomers Polymerisable Plasticizer for polyacrylates, polyesters, PVC Levelling/Wetting agent and Adhesion Promoter for metal for UV curable systems 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. Mixture of methacrylated mono-and di-phosphate ester. Used as a solvent free UV-curable additive for paints, lacquers and printing inks. Can be used as a polymerisable hydrophilic non-ionic surfactant and a co-polymerisable plasticizer for polyacrylates, polyesters and PVC. Offers easy handling and very good levelling/wetting properties. Improves adhesion to metal surfaces in UV-curable systems, wetting of substrates like wood and metal and storage and mechanical stability. Reduces grit building and foam formation. Gives no migration of non-ionic surfactant, improved wet-scrub resistance, improved adhesion to metal, high yellowing resistance even after enamel application, flame retardant properties and some degree of crosslinking without gel formation. Use level: 0.5-2.5 %wt based on monomers.
