522-1410 Plastiprimer MDF White Post-Cat Pigmented Primer

This product is designed only for MDF and offers excellent filling capabilities due to its high solid content (50% volume).

Substrate should be sanded using 120, 150 or 180 grit stearated paper. Plastiprimer MDF cannot be used on metal, old oil or cellulose lacquers. Suitable topcoats are Plasticolor White 117-10XX, ES Lacquer II White 131-11XX, Variset® 131-70XX or Variset Plus 131-71XX.

Mix Plastiprimer MDF thoroughly, then catalyze and reduce material as recommended. Plastiprimer MDF must be well mixed while adding catalyst and reducers and must be agitated at all times to ensure product consistency.

Plastiprimer MDF is applied in one to two coats and can be used as a primer over MDF or HDF type products. A thorough sanding using 240/320 grit stearated paper between coats is essential for adhesion. The second and subsequent coats must be applied the same day as the previous coat is sanded. Care should be taken to avoid sanding through the primer coat. With profiled edges, care must be taken with sanding of primer to avoid sanding through sharp edges. Complex profiles or profiles with sharp corners may cause difficulties in obtaining an effective primer coat of even thickness. In these cases, profile design must be discussed with your technical representative. Contact with metal surfaces should be avoided once the Plastiprimer MDF has been catalyzed. To ensure proper uniformity, the material should be agitated at all times. Recommended film build of Plastiprimer MDF is not to exceed 4 mils dry. Total recommended film build of Plastiprimer MDF and topcoat is not to exceed 6 mils dry.

Plastiprimer MDF must not be polluted with oil, varnish or the like and must not be sanded with steel wool between coats. Plastiprimer MDF must not be used and dried at temperatures below 64°F or relative humidity above 65%. During the curing process, the coating must not be exposed to ammonia vapors. Ammonia cleaners should not be used for cleaning the finished surface. This may accelerate discoloration.
