Surface Preparation

Substrate must be sanded using 120 or 150 grit stearated paper prior to staining or coating.  Sealers 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 24 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 24 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 24 has been catalyzed. 

This product can be used as a sealer under Chemlife 24 Topcoat 421-63XX. Consult with your coatings supplier for specific recommendations.

Chemlife 24 demonstrates excellent resistance to marring, dry heat, moisture, household and office liquids, etc. 

Total recommended film build of the Chemlife 24 system should not exceed 4 mils dry.

Chemlife 24 must not be polluted with oil and must not be sanded with steel wool between coats. 

Chemlife 24 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.
