Polyurethane 250

APF POLYURETHANE 250 is a two-component, low viscosity acrylic urethane for use as a primer/sealer over a variety of surfaces. The use of special solvents and adhesion promoters gives this material excellent penetration and adhesion to minimally profiled concrete. APF POLYURETHANE 250 is UV stable for use in exterior applications, cures rapidly, and may be re-coated with both solvent-based and water-based polyurethanes. When used as a finish coat, this material creates a hard, high gloss surface that offers excellent stain resistance and easy cleanability. Compared to solvent-based acrylic sealers, APF POLYURETHANE 250 offers substantial improvements in gloss retention, and overall performance. APF POLYURETHANE 250 is available in a satin finish. A low VOC version of this material is available to meet environmental regulations.

APF POLYURETHANE 250 is designed for application over concrete, acid stained surfaces, and various types of architectural concrete. It has excellent performance as a sealer for pavers and new un-waxed saltillo tile. It is suitable over acid stained concrete as it is unaffected by pH drifts that can affect the adhesion of other types of primers. When applied over acid stains or integrally colored concrete, it gives color enhancement similar to solvent acrylic sealers. APF POLYURETHANE 250 can also be applied as a tie coat over difficult to adhere to surfaces such as polyester urethane. When applied as a finish coat in vehicle areas, it resists tire marking and provides an easily cleaned surface.
