Storage & Handling

Installation Guidelines

Empty entire contents of component B into component A. Mix it by using a low speed drill (ca. 300 U/min) for 3-5 minutes. In order to avoid mixing errors the mixture should be poured into a clean container and mixed again for 1 minute. Apply the mixture with a high quality roller, brush or squeegee. If solvent was added to the product, it is important that the solvent has evaporated completely before applying the coating. PC 11-020 is insensitive to moisture. Nevertheless, it is important to protect uncured PC 11-020 against moisture. Moisture may induce the formation of bubbles, which may reduce adhesion strength. Open time 48 h. If this time is exceeded, the primer coat should be slightly grinded or a new primer coat should be applied.
Consumption:
Solvent-free approx. 150-200 g/m²

Storage
