NOTE |
1. Adhered moisture, grease, and dirt on substrate must be cleaned thoroughly. 2. Using specified thinner to avoid formation of bubble and pinhole. 3. Due to the limit of pot life, once the container is opened, it must be used up within 3 says. 4. Since the paint is easy to react with moisture in air and causes bubble and gelation as a result. Therefore, the container should be tightly closed to avoid the reaction with moisture. After it is opened, the thinner should be added to leftover or to sealed the container so as to prevent the formation of bubbles and gelation. 5. The supervision over
application is necessary, because DFT above 80 |
