The paint is a one-component room temperature drying chlorinated rubber coating. It has excellent low-temperature construction performance, mutual solubility between the coating and the coating, and excellent interlayer adhesion. The coating dries quickly, has good mechanical properties, abrasion resistance, impact resistance and alkali resistance, and has good water resistance, weather resistance, dry and wet resistance. The paint film and the primer with cathodic protection function have good compatibility and good durability. But poor oil resistance.
