          Purpose :
          Appearance :

          1900 Polyurethane conductive paint is based on isocyanate adduct and hydroxyl-containing polyester resin as the base material, adding two-component coating composed of conductive material. 1900-1 is based on epoxy resin and curing agent for the base material and inert anti-rust paint composed of two-component oil primer. The coating system composed of 1900 conductive paint and 1900-1 primer has the properties of resistance to various petroleum products, has no influence on the quality of oil, has good oil resistance and water resistance, and has good electrical conductivity, and its resistivity is less than 106? Cm, to prevent the accumulation of static electricity inside the tank, to prevent fire hazards, to ensure the safety role. In order to improve the chemical resistance of paint film, 1900 polyurethane conductive paint must be used with the 1900-1 primer. The matching method is as follows:

          Precautions 

                        Oil tank steel plate after sandblasting treatment, in order to prevent re-rust, must be painted within 6 hours of the first 1900-1 primer

                        The relative humidity in tank or tank should not be higher than 75%

                        * 1900-1 primer and 1900 conductive paint are two-component paint, with the former group B into the first group, or according to the required ratio of deployment, with the number of how much allocation, mixing evenly after use. After the preparation of 1900-1 primer used in 8 hours, 1900 conductive paint used up within 5 hours. Temperature is higher than 25 , the pot life is shortened accordingly

                        1900-1 thinner used in the primer and 1900 thinner used 109 conductive paint must be dedicated, not interchangeable, not to make mistakes, so as not to cause losses

                        * With paint and coating process, 1900 conductive paint not with water, acid, alkali, alcohol and other contact. 1900

          Conductive paint component B is easy to react with water, alcohol and other materials, with paint after the remaining part of the B group of drums must be tightly sealed to avoid the loss of cement

                        Construction tools must be clean and dry, immediately after use with special thinner wash, should not be placed in water

                        In order to make the 1900-1 primer and 1900 conductive paint A, B two components fully cross-linked and cured completely, with paint after 25 at the temperature of 30min curing was preserved after the original coating. If the temperature is below 25 can be appropriate to extend the aging time

                        The construction of the tank must pay attention to labor protection, the use of low-pressure lights, to strengthen ventilation, ventilation must meet safety requirements. Construction workers to wear ventilation masks, construction time can not be too long, to regularly out of the tank to breathe fresh air

                        After the construction, must be in a certain period of time to continue to take ventilation measures to discharge paint drying process of evaporation of solvents to ensure that the film drying and curing

                        Do not rush to finish painting, must ensure that adequate drying time, otherwise it will make early vesicles film. Temperature 25 in the case of adequate ventilation, at least 7 days before loading oil. Temperature below or above 25 , may be appropriate to extend or shorten the drying time

          Remark For the correct use of our products, please carefully read the "User's Guide" in this manual.

          Statement The above data and data are based on our test and practical experience in the use of accumulated and can be used as construction guide. We do not understand the situation in the construction, we only guarantee the quality of the paint itself, other issues will not be responsible. For this manual, we will be based on the continuous improvement of products have the right to modify.
