Createx UVLS Clears are water-based, architectural-grade clears that are suitable for interior and exterior applications. They are made with an aliphatic acrylic polyurethane resin, which is exceptionally durable with excellent adhesion. Clears are durable and do not yellow over time. They can be used as a top-coat clear for signs, theatrical costumes, modelling, etc., as primer (adhere to most any substrate except silicone), or as a carrier medium for Candy2o Dyes. They can be applied by spray gun, airbrush or traditional brush. UVLS stands for Ultra-Violet Light Stabilizer, as these clears protect underlying colours.
