Note:

Surface Preparation

Substrate must be sanded using 120, 150 or 180 grit paper prior to priming. Primer should be sanded with 280/320 grit paper prior to being coated, The Primer should be coated within eight hours of being sanded. Appropriate primer is the Chemcraft Acquaduro™ Primer 550-1760. When recoating, the previous coat of the Acquaduro™ 2K Polyurethane Waterborne Topcoat must be sanded and the next coat applied within eight hours of being sanded.

General Information

**After mixing part A and part B to the correct ratio, water can then be added to reduce viscosity prior to application as needed depending on spray equipment. A maximum of 10% water can be added to the fresh (immediately after the part B is fully dispersed into part A) catalyzed material.
Note: Adding extra water during application is not recommended as this will have a direct impact on the pot life. The pot life of the mixture will be reduced significantly and the mixture will gel quickly.
The mixed product contains 876-3400, an isocyanate based co-reactant. Please follow all precautions associated with handling and use of those materials. Refer to MSDS for detailed information. Product must be thoroughly stirred before adding the hardener in the recommended ratio. The viscosity of the product should be monitored after mixing with the hardener. The relative humidity in the application and drying room should not exceed 75% for maximum coating performance. 

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.
