SUNCOAT TM  High Viscosity Chlorinated Natural Rubber

Name of the Product

Commercial name: Chlorinated rubber

 

Chemical molecular formula: (C10H11Cl7) n


Introduction of Chlorinated rubber 

The chlorinated rubber is a derived product modified from the natural rubber through chlorination. It finds wide application in
the production of coatings, inks, adhesives, etc. The company has a working capacity of 1500 tons of the chlorinated rubber
with advanced technology and fine equipment. The quality of the product is stable and reliable. The product is trustworthy and
well received by the customers.
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 toimprove its quality, while the low-viscosity
product is applied to high-grade ink making.


Production Process

Chlorinated rubber products production process: Chlorinated rubber products are produced by dissolving natural rubber in non-ODS
organic solvents and then through a series of process including chlorination synthesis, chemical neutralization, hydraulic analysis,
centrifugation, washing, and drying.
