Chlorinated rubber (CR) are physically drying paints. They are widely used as industrial coatings in chemical plants, refineries, tank farms, bridges etc. CR has very good resistance to water and has traditionally been used on ships and other marine structures both above and below the waterline.

Chlorinated rubber coatings are one-component and dry by evaporation of the solvents. They are therefore not so sensitive to the ambient temperature during application and drying.

They are resoluble which can be considered both as a positive property, but may also be negative: The positive effect will in most cases be the dominating factor as resolubility gives flexible overcoating time, with basically no danger of flaking between coats. The negative side will be that CR-based products are not resistant to most solvents. This implies that strong solvents may destroy the paint film, and in addition there is a danger of solvents being entrapped in the paint film. This happens especially when overcoating a thick CR-system at low temperatures.

• Physically drying
• Not temperature dependent
• Easy to recoat
• One component
• Very good water resistance
• Relatively good chemical resistance

• Poor solvent resistance
• Low solids content
• Relatively poor wetting properties
• Thermoplastic
• Dry heat resistant up to approx. 70^oC
• High content of volatile organic compounds (VOC)
• The chlorinated compounds give off chlorine on ageing
