Direction

Stir this coating before its application and necessary temperature of stir need to be less than 15℃, or else it need to be mixed with thinner for attaining its necessary viscosity level after stirring. One can also utilize dynamic mixer for blending this item with other raw materials. Its rate of cure depends on various factors like moisture level, temperature, air circulation level, thickness of film, thinner and so on.
Over dosage of thinner can results in its slow cure rate. The thinner, therefore, should be added with it after mixing. The spreading rates need to be lowered between 5%—25% to reduce wastage rate during its various applications.

Application
Steel : The surface of steel item need to be cleaned and dried prior to the application of this coating. This surface need to be devoid of oil and all sorts of pollutants. It is advised not to use this coating at the time of rain, high wind blow, fog, snow or in case the surface has less than 3℃ temperature or above the dew point or the temperature is higher than 40℃ or below 5 degree C.
Brush/Roller : It is ideal for small areas. It is suggested to apply this coating on the required surface in an uniform manner.  If required, mix this coating with Epoxy thinner X-5 in 0-15% amount to reduce its density.
Conventional Spray : Though thinning is necessary, yet one can blend 0-15% of Epoxy Thinner X-5.
Airless Spray : One can add 0-15% of Epoxy Thinner X-5 with this coating, if required. The pump ratio need to be maintained in 23:1 or 32:1 ratio. In that case, the fluid tip should be 0.33-0.38 mm.
Over coating : ‘X’cut or crosshatch method is adopted to determine the age of applied coating. In case it lifts, it is suggested to erase it. The coating surface need to be oil and grease free and it should be free from contaminants.
Clean Up : It can be removed by applying Epoxy Thinner X-5.
Safety: Special care need to be taken during its application. Wear protective mask to avoid its inhalation. Store it away from the source of fire as this coating is flammable. It should be preserved away from dry chemical gas and Co2. It releases harmful fumes on burning.
