It improves pigment wetting, improves adhesion, is widely compatibile with alkyd vehicles, has higher pigment lading and air-drying reactivity. APPLICATION AND PROPERTIES DAPRO® FX 521 is used as a co-monomer for polymerisation purpose, e.g. for acrylic resins.DAPRO® FX 521 contains conjugated unsaturated groups, which are reactive for oxidative polymerisation reactions. Thus, introducing DAPRO® FX 521 in the polymeric chain results in air-drying properties for the polymer. Also the compatibility with oil-based, such as alkyd resins will be increased. Paints based on alkyd binders. Chemically or physically modified with DAPRO® FX 521, show improved properties with respect to adhesion onto metals or previously painted surfaces. Wettability,flow, levelling, package stability and durability are also improved. Dispersion paints are modified with DAPRO® FX 521 to improve adhesion to chalky surfaces or metal brushability, whereby flow and levelling properties are also positively influenced.DAPRO® FX 521 improves pigment wetting in both aqueous as well as solvent-based systems. Alkyd resins can be modified chemically by re-reaction with the unsaturated oil and the vinyl groups; DAPRO® FX 521 can be copolymerized with vinyl monomers.
