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 allowed it to cure very fast and allowed the copolymerization of natural and synthetic rubbers. Chlorinated rubbers were also harder and more durable than their non-halogenated counterparts. It was also used to produce a hard tough, glossy film that was used 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.
