Resiflow PV-88 is widely known in Europe for its reliable performance as a flow control agent for general industrial powder coatings. It is well suited for the spectrum of common binder chemistries including polyesters, polyurethanes, hybrids, epoxies, and acrylics. Resiflow PV-88 is based on a liquid acrylic polymer that has been converted into free-flowing powder by adsorption onto silica-type filler. For best results, Resiflow PV-88 should be dry-blended with other coating raw materials, then homogenized in a heated extruder. The active ingredient is released and homogenized with the other components during extrusion, and results in a uniform system. Surface defects such as orange peel, craters, pinholes, and other imperfections can be reduced or eliminated by incorporating 0.7-1.5% of Resiflow PV-88 into powder coating formulations. As with any raw material, laboratory evaluation is required for each formulation to determine the best processing method and the optimum concentration of the additive.
