Description
UltraFlex PW – Solvent-Free Two-Component Polyurethane Waterproofing Membrane
UltraFlex PW is a solvent-free, two-component aromatic polyurethane liquid membrane designed for permanent contact with potable water. With 100% solids content and thixotropic properties, it forms a seamless, elastic and fully watertight membrane once catalysed, delivering long-term durability and resistance to wear.
The system is CE-marked and WRAS approved in accordance with British Standard BS 6920, confirming its suitability for use within drinking water containment systems. Testing to EN 12873 supports compliance with applicable water safety requirements.
