Surface Preparation

Wood substrate should be sanded with 120,150 or 180 grit paper prior to staining or coating. Sealer should be well sanded using 240 or 320 grit stearated paper. A first coat of Isolante is recommended, please refer to SOP for application.

General Information

Mix the desired amount of material and apply 4-5 mils wet. The relative humidity in the application and drying rooms should never exceed 75%. Viscosity on the catalyzed material should be monitored regularly to maintain a consistent appearance. Mixed product will contain 999-062, an isocyanate base co-reactant. Please follow all precautions associated with handling and use of these materials. The total recommended film thickness of D-Dur system is not to exceed 6 mils dry.

The completed coating system should be checked for required properties prior to the start-up of production.

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.
