Description

Chlorinated Rubber is a high-performance, chemically modified polymer produced by the chlorination of natural or synthetic rubber. This process yields a material with exceptional chemical resistance, flame retardancy, and durability, making it a critical component in protective and industrial coatings. It is essential for manufacturers requiring long-lasting protection against harsh environments, including marine, chemical, and infrastructure sectors. Key industries that rely on this versatile resin include paints & coatings, adhesives, inks, and corrosion protection.

Application

• Marine & Protective Coatings: A primary binder in high-performance paints for ships, offshore structures, and shipping containers due to its excellent water and salt spray resistance.
• Industrial Maintenance Paints: Used in heavy-duty coatings for chemical plants, factory floors, bridges, and steel structures for superior corrosion and abrasion resistance.
• Fire-Retardant Paints & Intumescent Coatings: Leverages its chlorine content to provide flame retardant properties in safety-critical applications.
• Adhesives & Sealants: Imparts strong bonding power and chemical stability in contact adhesives and mastics.
• Printing Inks: Used in specialty inks, particularly for metal decoration and plastic films, offering good adhesion and fast drying.
• Paper & Textile Coatings: Provides moisture barrier and chemical resistance properties for technical papers and industrial fabrics.
• Underwater Applications: Ideal for anti-fouling paints and coatings for submerged structures.
