What is chlorine rubber resin ?

Chlorochrome saddle is a raw rubber found in nature neoprene or isoprene polymer with a spring-like chain that has elastic properties. Chlorocaust resin is formed during the incremental and desalination reactions of natural rubber in carbon tetrachloride solution. Chloro-rubber is prepared in the form of white powder and has 65% chlorine, which when used, turns into a liquid state with a suitable solvent. Chloro-rubber dissolves well in cyclic hydrocarbons, esters, ketones and chlorinated solvents, but is completely insoluble in aliphatic hydrocarbons and alcohols. The molecular weight of chloro-rubber resin is usually more than 500, and the higher the molecular weight, the higher the viscosity of the resin. Chloro-rubber resin alone or in combination with other resins, including Alkyd Short Oil resins, is used in the formulation of pool paints, marine paints, traffic paints and street table liners. Chloro-rubber paints are a good coating for steel, iron and cement surfaces and are used for ship hulls, bridges, boilers, pipes and roofs of industrial sheds.


Poor water and moisture absorption, non-flammability (due to the presence of chlorine atoms) and high electrical resistance make a special type of chloro-rubber resin suitable for covering power cables. Chloro-rubber resin is compatible with many other resins such as alkyd short oil, acrylic, phenolic, epoxy, vinyl as well as natural resins such as bitumen, nitrile rubber and coumarone. Chloro-rubber resin is sensitive to sunlight and UV rays, and pigment-free paint is never recommended for outdoor use.

By using suitable pigments, stabilizers or corrective resins, the resistance of chloro-rubber resin can be increased to the desired level.

One of the understanding properties

One of the outstanding properties of this resin is its good resistance to alkalis and chemicals. This resin is well resistant to most mineral acids; However, at temperatures above 60 ° C, this resin is subject to the destructive effects of concentrated mineral acids. In the presence of oxidizing agents and at room temperature, chloro-rubber resin has good resistance, but with increasing temperature, its resistance decreases and the paint is destroyed. 

When we use this resin

When using chloro-rubber in alkaline conditions, it should be noted that the percentage of alkyd resin in the formulation is very low because alkyd resin is hydrolyzed and degraded in the presence of alkali. Chloro-rubber paints are also recommended for coating concrete surfaces due to their good resistance to alkalis and water. Chlorocaust is a thermoplastic resin and has a limited thermal resistance, so it is resistant up to 60 ° C in wet environments and up to 93 ° C in dry environments. Drying of the resin is by evaporation of solvent and no chemical reaction takes place, so at high temperatures the resin will soften and leak. In addition, this resin is resistant to -32 degrees Celsius and at sub-zero temperatures, the hardness and brittleness of the resin increase.
