S-MATT clear solvent-based 2K polyurethane topcoat
OPX301 creates a clear ultra-matt surface with a uniform appearance, anti-glare performance, resistance to yellowing, and the ability to recover from minor surface marks. It is spray-applied over a prepared solvent-based 2K base coat.
A clear solvent-based finish for interior furniture, fronts, doors, and flat panels with near-zero gloss.
Sand the solvent-based 2K base coat with P400-P500. Remove dust thoroughly with compressed air.
Add 30% C200 hardener. Thin with up to 20% D1010 when required. Mix mechanically or manually.
Apply with a cup gun using a 1.7-1.9 mm nozzle at 2.0-2.5 atm, or by Airmix with a 0.009-0.011 inch nozzle. Apply 80-100 g/m2.
