KingProof PUB100®
One component, polyurethane-bitumen liquid membrane for flashing, waterproofing and protection.
Overview
KingProof PUB100 is a quick-curing, one component, thixotropic, bitumen-extended polyurethane fluid based on pure elastomeric hydrophobic polyurethane resin and is extended with chemically polymerised virgin bitumen. It produces a hydrophobic, elastic membrane with very strong adhesion to most types of substrate, as well as bituminous, and excellent mechanical and chemical resistance properties. It is ideal for application on vertical surfaces: no running, no blubbing.
Applications
- Waterproofing and protection of:
- Foundations
- Wet areas (Bathrooms, kitchens, etc.)
- Shaded roofs (i.e. unexposed to UV)
- Vertical and horizontal substrates
- Cementitious substrates
- Irrigation channels
- Gypsum and cement boards
- Asphalt membranes (for repair also)
Advantages
- Fast curing
- Excellent adhesion to almost any surface
- Excellent thermal resistance and service temperatures
- Cold Resistance: the film remains elastic down to minus 40ºC
- Excellent mechanical properties, high elongation, high tensile and tear strength, high abrasion resistance
- Thixotropic consistency, easily applied on vertical surface and complex shapes without running or bubbling
- Excellent chemical resistance
