In coatings to remarkably improve the coating properties such as weatherability and water resistance, insulation, inflammability, anti-acidity, anti-alkali, adhesion as well as impact strength. The chlorinated rubber coatings is widely applied to surface protection of materials for severe situation, such as shipping, offshore platforms, bridges, docks, containers, motor vehicle chassis, road signs, chemical equipment, etc. Additionally, high viscosity chlorinated rubber is applied to high-strength adhesives production, or added into other rubber products to improve its quality, while the low-viscosity product is applied to high-grade ink making.
