DIRECTIONS Before using stir or using dynamic mixer mixing two components completely,Just mix a good raw material and mixing of raw materials before can not be together. Rate of cure will vary depending on temperature and other factors such as ventilation, film thickness, humidity, thinner. The temperature of stir will >15℃, otherwise thinner should be added for needed viscosity after stir.
Overmuch thinner will lead sag and slow cure rate, thin film. Practical spreading rates may be reduced 5—25% for wastage of different application conditions.

APPLICATION  STEEL:Steel surface must be prepared by abrasive blast cleaning to ISO Standard Class Sa2.5 or power tool cleaning Class St3. The surface coated by shop primer should be dry, clean and no dirt, take the second descaling where film damaged or corrosion, and achieve Sa2.5 level or St3 level. Clear the zinc salt with high pressure fresh water or sand. Weld
and the damage parts processing to Sa2.5 level or St3 level.
Don’t apply at temperatures below 5℃ or above 40℃. Don’t apply at relative humidity above 85% or when the surface is less than 3℃ above the dew point.
Don’t apply if there is fog, rain, snow or strong wind.
 
weather condition: The relative humidity < 80%. Usually need good ventilation, to ensure
paint dry
BRUSH/ROLLER: Suitable for small areas only. Apply even coats of the mixed material to the prepared surface. Thin if necessary with up to 0-5% with Epoxy Thinner X-100. Additional coats may be required to attain specified thickness.
CONVENTIONAL SPRAY: Thinning is not normally required, however 0-5% of Epoxy Thinner X-100 can be added.
AIRLESS SPRAY: Thinning is not normally required, however 0-5% of Epoxy Thinner X-100 can be added. Pump ratio is 32:1 or 45:1 and fluid tip is 0.43-0.48 mm.
Overcoating: Aged coating should be tested for lifting by a method such as ‘X’cut or crosshatch methods. If it lifts, remove it. The surface must be free of oil, grease and other contaminants.
CLEAN UP: with Epoxy Thinner X-2


SAFETY:Pay attention to the safety precautions before and after using this product. Users should comply with the provision of the respective country or local government. It’s dangerous or deadly to eating it. To avoid inhalation of thinner steams and spray mists.
Use protective wears correctly; the skin and eyes should avoid contacting it. Use with good ventilation. This product is flammable. All sources of ignition must be eliminated in, or near the working area. DO NOT SMOKE. Fight fire with foam, CO2 or dry chemical powder. On burning will emit toxic fumes.
