Tools:
Airless spray: the fluid tip diameter is from 0.43mm to 0.65mm, min output fluid pressure is 15MPa (150kp/cm2). The angle of spray from 400to 650.
Conventional spray.
For inconsiderable surfaces: brush can be used, care must be taken to achieve the specified dry film thickness.
Clean tools after using.
- The practiced surface should be clean, dry and free from oil and grease.
- Firstly, Stir well the base (part A) with an agitator, then pour the hardener (part B) slowly into the stirred base (part A), and mix them (part A with part B) together thoroughly in the ratio of 4 to 1.
- Thinner should be only used in the case of exceptional circumstances (max. 3% by the weight of A & B mixture).
- The available A & B mixture must be used within the pot life (6 hours at 230C).
- The practiced surface temperature is more than 100C (It’s at least 50C above the dew point) and the practiced space humidity is equal or less than 85%.
- Drying time depends on temperature, humidity and ventilation of application space. High temperature and good ventilation help the drying time to be more quickly.
