KingProof PU100®
Polyurethane liquid membrane for waterproofing and protection.
Overview
Single component high-quality polyurethane coating that cures by reacting with the humidity in the atmosphere to form a strong elastic film with excellent adhesion to different substrates. Can be applied by brush, roller or airless spray machine. The product is based on pure elastomeric hydrophobic polyurethane resin with special inorganic filler that provides the material with excellent weathering resistance
Applications
- Waterproofing and protection of:
- Roofs
- Light roofing made of metal or fibrous cement
- Wet areas, bathrooms and kitchens
- Verandas and balconies
- Gypsum and cement boards
Advantages
- Excellent adhesion to all common primed substrates
- Excellent water and UV resistance. The white colour reflects much of the solar energy reducing the internal temperature of the building
- Excellent thermal resistance. Max service temperature 80oC, max shock temperature 200oC
- Cold Resistance: the film remains elastic down to minus 40oC
- Excellent mechanical properties
- Good breathability characteristics which minimize the accumulation of humidity under the coat
