Chlorinated rubber offers robust chemical- and water- resistance : Pergut®

Pergut® fast-drying powdered chlorinated polymers from Covestro are ideal for highly durable coatings, printing inks, adhesives and primers.

Produced from polyisoprene and polybutadiene in varying molecular weights and viscosities, Pergut® polymers contain between 64.5 percent  and 67 percent  chlorine and have a density of 1.6 g/cm3.

Covestro’s proprietary manufacturing process allows Pergut® chlorinated rubber products to have an extremely low carbon tetrachloride (CCl4) content of < 0.005 % by weight (< 50 ppm) and comply with global regulatory requirements.

Pergut® chlorinated rubber polymers are suitable for the formulation of many types of products:

• Heavy-duty corrosion protection coatings
• Anti-fouling coatings
• Swimming pool coatings
• Flooring systems
• Printing inks
• Metal rubber primers

Chlorinated rubber coatings provide several high-performance characteristics, such as:

• Easy to use (one-component systems)
• Fast drying
• Good adhesion to metals (steel, iron, zinc)
• High resistance to corrosion, water, chemicals and salts
• Resistant to weather and other environmental influences
• Anti-fouling properties, including resistance to bacteria, mold and fungi
• Wide compatibility with many solvents, resins, pigments, fillers and additives
• Excellent repaintabiltiy, even after many years
• Long-term storage stability
