Melos PC 11-020
- Chemical Family
- Polyurethanes (PU)
Melos PC 11-020 is a solvent-free, two-component polyurethane primer. It shows an excellent adhesion to concrete and screed. PC 11-020 has a very good acid- and alkali resistance. It is possible, but not necessary, to add solvent.

- Safety Guidelines
Adequate ventilation or use of a respirator (filter A2) is required in enclosed spaces. We recommend approved eye protection and gloves during application.
- 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
