POLEPOX-PB 2000
Two-component, 1:1 ratio by volume, polyurethane (A) and bitumen (B) liquid membrane used for waterproofing and protection. It is a fast-curing, bitumen-extended polyurethane fluid. It produces a highly elastic membrane with strong adhesion to many types of surfaces and excellent mechanical and chemical resistance properties. It is based on a pure elastomeric hydrophobic polyurethane resin extended with chemically polymerised virgin bitumen.
Recommended For
Waterproofing and protection of:
- Gypsum and cement boards,
- Polyurethane insulation foams,
- Asphalt membranes and EPDM membranes,
- Bathrooms and verandas/balconies (under tiles),
- Flower pots and roof-top gardens,
- Light roofing made of metal or fibrous cement,
- Non-potable water tanks,
- Basements and foundations,
- Bridge platforms,
- "Cut-and-cover" tunnels,
- Irrigation channels.
Features & Benefits
- Components easily mixed 1:1 by volume with fast curing.
- Thick, bubble-free membrane possible.
- Unmixed quantities can be stored for later use as it is a two-component product.
- Low modulus provides excellent substrate crack-bridging properties.
- Excellent adhesion on almost any surface with or without special primers.
- No thinning required, but solvent may be used.
- Excellent thermal resistance; max service temperature 80°C, max shock temperature 200°C.
- Cold resistance; the film remains elastic even down to -40°C.
- Outstanding mechanical properties: high elongation, tensile and tear strength, high abrasion resistance.
- Good chemical resistance and water vapor barrier properties.
Application Prerequisites & Procedure
Substrates: Can be applied on concrete, fibrous cement, mosaic, cement roof tiles, well-adhered acrylic/asphalt coats, wood, corroded metal, and galvanized steel.
Surface Preparation: Clean the surface using a high-pressure washer if possible; remove oil, grease, and wax. Cement laitance, loose particles, and old membranes must be removed. Standard concrete conditions: Hardness R28=15Mpa, Humidity <10%, Temperature 5-35°C, Relative humidity <85%.
Application Procedure:
- Priming: Choose primer from the Selection Table and follow its specific instructions.
- Mixing: Mix equal volumes manually or with a low-speed (300 rpm) mixer.
- Application: Apply immediately after mixing. Pot life is 30-45 mins at 20°C. Apply with brush, roller, spatula, or airless spraying.
