Directions for Use
Surface Preparation
Substrate must be sanded using 120 or 150 grit stearated paper prior to staining or coating. Sealers, if used, should be sanded with 240, 280 and 320 grit stearated paper prior to being coated. The substrate as well as the sealers should be topcoated within eight hours of being sanded. Chemlife cannot be used on metal, old oil or cellulose lacquers. Stain systems used under acid catalyzed systems should be acid stable. AkzoNobel recommends using 825-90XX, 825-91XX Promatch® C-Mix Stains or 890-85XX Promatch Dye stains.
General Information
Catalyze and reduce the material as recommended. Chemlife is applied in one to three coats on all kinds of wood meant for indoor use. Thorough sanding between the coats is a must for good adhesion. The second and subsequent coats must be applied the same day as the previous coat is sanded.
Contact with metal surfaces should be avoided once the Chemlife has been catalyzed. To ensure proper sheen, the catalyzed material should be agitated at all times.
This product can be used as a self-sealer. Appropriate sealer is Chemlife 24 Conversion Varnish Sealer 421-6300 or Chemlife 24 Conversion Varnish Primer 522-2400. Consult with your coatings supplier for specific recommendations.
Chemlife demonstrates excellent resistance to marring, dry heat, moisture, household and office liquids, etc. When this product is used as its own sealer, its special formulation ensures excellent filling and easy sanding properties with superior holdout for subsequent coating. Chemlife must be thoroughly stirred, while adding catalyst and reducer in the recommended ratio. Total recommended film build of the Chemlife system should not exceed 4 mils dry.
Chemlife must not be polluted with oil and must not be sanded with steel wool between coats.
Chemlife 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.
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.
