| Product Description |
KEMPEROL 2K-PUR is a two-component, UV-stable high performance seamless and self-terminating cold fluid-applied polyester reinforced solvent-free polyurethane membrane system. KEMPEROL 2K-PUR membranes can be surfaced with polyurethane coating, light-reflective sand aggregate surfacing or other granular materials to match the appearance of the surrounding substrate. |
|
| Composition & Materials | A monolithic membrane is created in the field by combining the KEMPEROL 2K-PUR 2-part, cold-applied liquid polyurethane resin with KEMPEROL polyester reinforcing fleece. | |
| Recycled content | 0 % | |
| Renewable Resources | Up to 80 % castor oil | |
| Use | KEMPEROL 2K-PUR membranes are suitable for a wide range of interior and exterior waterproofing applications including mechanical rooms, plazas, roofs, planters, foundations and flashings. | |
