Polycoat® WW

High Performance Tanking and Lining Membrane

ULFCAR® Polycoat WW is a two component, seamless liquid system based on polyurethane and polyisocyanate to produce coatings with high durability and outstanding physical properties. Polycrete WW forms a tough, flexible coating especially suited to applications where abrasion and chemical resistance are required.

Case Study


  • Resistant to waste water, chemical and mineral pollutants.
  • Excellent weathering and UV resistance.
  • Excellent chemical, abrasion and impact resistance. 
  • Two component colour coded system for on-side homogenous mix. 
  • Liquid membrane accommodates difficult shapes and profiles. 
  • Solvent free and easy to apply in confined areas.
  • Seamless liquid applied membrane with low gas permeability.
  • High bond strength to a variety of substrates.

Areas of application:
A membrane to retain, exclude or protect from water, oils, fuels and many aggressive chemicals in the following applications:

• Storage Tanks
• Silos
• Silage Units
• Bund Linings for Groundwater Protection
• Internal Lining of Sewerage Tankers
