Polyurethane 525 Primer High Performance Coating: Features and Usage
Polyurethane 525 Primer is a water-based two component polyurethane formulated for use when a rapid curing, high adhesive primer over concrete is required. The material is fortified with a UV absorber package and is suitable for both interior and exterior use. It gives epoxy-like adhesion to both dry and damp concrete and dries for recoating in 15-60 minutes depending upon temperature, humidity and air movement. Polyurethane 525 Primer is low odor and VOC compliant.
Polyurethane 525 Primer was initially developed for use under water-based acrylic stains to improve adhesion to marginally prepared concrete. It leaves the host surface with a natural, non- darkened appearance which makes it ideal in clear driveway sealer systems and over acid stains where softer, more muted looks are desired. Polyurethane 525 Primer is also used over water- based and acetone based dyes.
Hydroxyl-functional polyol crosslinked with aliphatic polyisocyanate.
Clear base material may be tinted with Color Fuse pigment dispersions.
- Concrete must be clean and have a minimum profile of CSP2 (similar to 100 grit sandpaper).
- Keep application rate above 200 sq. ft. per gallon. Do not allow to puddle.
