Surface Preparation

Substrate should be sanded using 120, 150 or 180 grit stearated paper. Chemlife 24 Neutral Primer cannot be used on metal, old oil or cellulose lacquers. A suitable topcoat is Chemlife 24 421-63XX or Chemlife 24 White 117-24XX.

General Information

Mix Chemlife 24 Neutral Primer thoroughly, then catalyze and reduce material as recommended.  Chemlife 24 Neutral Primer must be well mixed while adding catalyst and reducers and must be agitated at all times to ensure product consistency. 

Chemlife 24 Neutral Primer is applied in one or two coats and can be used as a primer for most wood and wood products meant for indoor use. 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 Chemlife 24 Neutral Primer has been catalyzed. To ensure proper uniformity, the material should be agitated at all times. Recommended film build of Chemlife 24 Neutral Primer is not to exceed 4 mils dry. Total recommended film build of Chemlife 24 Neutral Primer and Chemlife 24 or Chemlife 24 White is not to exceed 6 mils dry. 

Chemlife 24 Neutral Primer must not be polluted with oil, varnish or the like and must not be sanded with steel wool between the coats. Chemlife 24 Neutral Primer 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 finish surfaces. This may accelerate discoloration.

THE CUSTOMER IS RESPONSIBLE FOR FOLLOWING THE RECOMMENDED APPLICATION PROCEDURES. FAILURE TO ADHERE TO THE RECOMMENDATIONS GIVEN IN THIS DATA SHEET WILL LIKELY RESULT IN UNSATISFACTORY FILM APPEARANCE OR FILM FAILURE. THE COMPLETE COATING SYSTEM SHOULD BE CHECKED FOR REQUIRED PROPERTIES PRIOR TO THE START-UP OF PRODUCTION.

Dry times are greatly affected by film build, porosity of substrate, air movement as well as heat and humidity. Temperatures are based on actual board temperature. This may vary depending on length of time for boards to reach these temperatures. Minimum curing temperatures of 64°F/18°C must be maintained throughout the curing cycle to achieve the film integrity as stated in product features.
