Description
An odorless, pale yellow resin prepared by adding up to 65% chlorine to an elastomer, such as natural rubber, Butyl rubber, or styrene-butadiene. Chlorination of rubber allwed it to cure very fast and allowed the copolymerizaqtion of natural and synthetic rubbers. Chlorinated rubber produces a hard tough, glossy film. It was used primarily in the 1950s -60s for paints, varnishes, adhesives, inks and paper coatings. Chlorinated rubber is still used for waterproof paints on floors and swimming pools. It is very resistant to chemicals and moisture.
Synonyms and Related Terms
