Product 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 highstrength adhesives production, or added into other rubber products to improve 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.

Applications
| Grade | Solubility / Thinnability | Properties / Applications |
| CR-5 | Generally speaking, R5 has good compatibility with many solvents, plasticizers and binders. However, it is necessary to test the solubility / compatibility in each case. | R5 can be used to formulate fast-drying anticorrosion coatings with good weather stability and resistance to water and chemicals. Used as a combination binder, for e.g. alkyd resins, acrylates and ketone resins. R5 improves the initial adhesion and water repellency of the system. |
| CR-10 | Generally speaking, R10 has good compatibility with many solvents, plasticizers and binders. However, it is necessary to test the solubility / compatibility in each case. | R10 can be used to formulate fast-drying anticorrosion coatings with good weather stability and resistance to water and chemicals. |
| CR-20 | Generally speaking, R20 has good compatibility with many solvents, plasticizers and binders. However, it is necessary to test the solubility / compatibility in each case. | R20 can be used to formulate fast-drying anticorrosion coatings with good weather stability and resistance to water and chemicals. It can also be used in abrasionresistant concrete floor coatings and roadmarking paints. |
| CR-40 | Generally speaking, R40 has good compatibility with many solvents, plasticizers and binders. However, it is necessary to test the solubility / compatibility in each case. | R40 can be used to formulate fast-drying anticorrosion coatings with good weather stability and resistance to water and chemicals. Used as a combination binder for e.g. alkyd resins, acrylates and ketone resins, R40 improves drying properties and resistance to inorganic acids. |
| CR-90 | Generally speaking, R90 has good compatibility with many solvents, plasticizers and binders. However, it is necessary to test the solubility / compatibility in each case. | R90 can be used to formulate fast-drying swimming pool and concrete coatings with good weather stability and resistance to water and chemicals. |
| CR-130 | R130 is soluble in aromatic and chlorinated hydrocarbons and in ethyl acetate. | On account of its high polarity, R130 is especially suitable for the formulation of primers and key coats for rubber/metal bonds. Binder for, among other things, adhesives. |
| CR-170 | R170 is soluble in aromatic and chlorinated hydrocarbons and in ethyl acetate. | On account of its high polarity, R170 is especially suitable for the formulation of primers and key coats for rubber/metal bonds. Binder for, among other things, adhesives. |
