Chlorinated rubber

Chlorinated rubber (CAS 9006-03-5), also marketed under the trade name Pergut, is a chlorinated natural rubber derivative used as a film-forming binder and rheology modifier in protective coating systems.

Its high chlorine content delivers inherent flame retardancy and resistance to moisture, chemicals, and corrosion. These properties determine its suitability across demanding industrial environments.

In marine and industrial coatings, it forms the backbone of anticorrosion primers and topcoats applied to ships, bridges, and steel structures where long-term chemical resistance is critical.

Road marking paints rely on it for fast drying, good adhesion to asphalt and concrete, and durability under heavy traffic. It ensures high performance in various weather conditions.

In printing inks, it functions as a binder that improves adhesion to difficult substrates including plastics and metal foils. This versatility makes it a staple in the packaging industry.

Construction adhesives and sealants incorporate it where flame-retardant formulations are required by building codes or project specifications. It provides essential safety features for modern infrastructure.

Chlorinated rubber is supplied as a free-flowing white to off-white powder. It is available in multiple viscosity grades, typically differentiated by solution viscosity measured in mPa·s.

This variety allows formulators to select the appropriate grade for their specific coating or adhesive system. Both technical and industrial grades are standard in the global chemical market.
