YMS modified epoxy inner wall coating performance and precautions
Modified epoxy inner wall coating is used for loading gasoline, diesel oil, kerosene, oil compartment and tank wall, oil resistance, solvent resistance, the inner wall coating has excellent adhesion, and impact resistance, and impregnated in these media insoluble, insoluble, and has good electrical conductivity and corrosion resistance.
Modified epoxy inner wall coating is a new type of oil and solvent resistant coating composed of epoxy resin grafted with high reactive groups and oil and solvent resistant groups as the base material and high reactive amines as the curing agent.
Modified epoxy inner wall coating is a scientific proportion obtained through a lot of experiments and careful calculation. Therefore, it is best to use a group of a group according to the ratio of good, to ensure that the ratio is correct, to ensure the performance of the coating. However, due to the grafting of highly reactive genes, group A and group B were mixed with high maturation and exotherm. With the increase of temperature, the curing reaction was further intensified, and it was cured without construction, resulting in waste. In order to match accurately and facilitate construction, it is recommended that group A and B be divided into five barrels quickly after mixing evenly, so that the total heat released by each barrel is reduced to one-fifth of the original, the material temperature will not rise too high, the curing reaction speed is slowed down, and the use time is extended to facilitate construction.
Points for attention of modified epoxy inner wall coating:
1. Group A and B shall be divided into five parts after being allocated, and it is best to use them up within 45 minutes.
2, in order to ensure that the coating excellent oil resistance, solvent resistance, after the construction, at room temperature curing for 15 days can be put in oil or solvent, low temperature to appropriately extend the curing time, to ensure that the coating oil resistance, solvent resistance.
