Resiflow PL-220

Resiflow PL-220 is a flow control agent for powder coatings that imparts unique compatibilizing and anti-cratering robustness properties to powder coating formulations while affording exceptionally smooth films. This product is suitable for multiple binder chemistries including polyesters, polyurethanes, hybrids, epoxies, and acrylics. The product is based on a liquid acrylic polymer that has been converted into free-flowing powder by adsorption onto silica-type filler.   Surface defects such as orange peel, craters, pinholes, and other imperfections can be reduced or eliminated by incorporating 0.7-1.5% of Resiflow PL-220 into powder coating formulations. For best results, the PL-220 should be dry-blended with other coating raw materials, then homogenized in a heated extruder.  As with any raw material, laboratory evaluation is required for each formulation to determine the optimum concentration of the flow additive, best processing method, suitability for the application and other specific requirements such as recoatability.
