HYPERDESMO-PB-2K Two-component liquid membrane for waterproofing & protection.
تماس بگیرید
CHARACTERISTICS:
HYPERDESMO-PB-2K is a fast-curing, two-component, 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 polymerized virgin bitumen. Apply with brush, roller, spatula or airless spraying. Minimum consumption: 1.0-1.5 lit/m2.

RECOMMENDED FOR
Waterproofing and protection of:
- Gypsum and cement boards
- polyurethane insulation foams
- asphalt membranes
- EPDM membranes
- bathrooms (under tiles)
- verandas and balconies (under tiles)
- flower pots and roof-top gardens
- light roofing made of metal or fibrous cement
- non-potable water tanks
- basements
- foundations
- bridge platforms
- cut-and-cover tunnels
- Irrigation channels
LIMITATIONS: Not recommended for unsound substrates.
FEATURES & BENEFITS
- Components easily mixed, 1:1 by volume
- Fast curing
- Thick, bubble-free, membrane possible
- Being a two-component product means that the quantities not mixed can be stored for later use
- Its low modulus gives it excellent substrate crack-bridging properties
- Excellent adhesion on almost any surface, with or without the use of special primers
- No thinning is required but SOLVENT-01 may be used
- Excellent thermal resistance, the product never turns soft. Max service temperature 80 oC, max shock temperature 200 oC
- Resistance in the cold: The film remains elastic even down to -40 oC
- Excellent mechanical properties, high elongation, tensile and tear strength, high abrasion resistance
- Good chemical resistance
- Good water vapor barrier properties
- Can also be used as a joint sealant
APPLICATION PREREQUISITES
Can be successfully applied on:
Concrete, fibrous cement, mosaic, cement roof tiles, old (but well adhered) acrylic and asphalt coats, wood, corroded metal, and galvanized steel. For information about other substrates, please contact our tech department.
Concrete substrate conditions (standard):
- Hardness: R28 = 15Mpa
- Humidity: W < 10%
- Temperature: 5-35 oC
- Relative humidity: < 85%
Primer selection for special conditions and substrates: Please refer to the Primer Selection Table.
APPLICATION PROCEDURE
Clean the surface using a high pressure washer, if possible. Remove oil, grease and wax contaminants. Cement laitance, loose particles, mould release agents, cured membranes, etc. must be removed.
Priming:
Choose primer from the Primer Selection Table and follow the application instructions given on its prospectus.
Mixing:
Mix equal volumes of the two components manually or with a low speed (300 rpm) mixer. Apply mixed quantities immediately. Pot life (of mix): 30-45 minutes at 20 oC. For application by airless spraying, the mix may have to be thinned with a small quantity of SOLVENT-01, especially for low-power applicators.
Crack bridging:
Apply HYPERDESMO-PB-2K (or HYPERDESMO-PB-1K) locally over any cracks larger than 1 mm before the main coat.
Application:
Apply the material with brush, roller or spatula.
CONSUMPTION
Minimum consumption: 1.0-1.5 lt/m2.
CLEANING
Clean tools and equipment first with paper towels and then using SOLVENT-01. Rollers will not be re-usable.
PACKAGING
2×5 lit, 2×20 lit and 2×200 lit.
SHELF LIFE
Can be kept for 12 months minimum in the original unopened pails in dry places and at temperatures of 5-25 oC. Cap tins air tightly in order to store unused quantities.
PRECAUTIONS
Contains a small quantity of volatile flammable solvents. Apply in well-ventilated, no smoking areas, away from naked flames. In closed spaces use ventilators and carbon active masks. Keep in mind that solvents are heavier than air so they creep on the floor. The MSDS (Material Safety Data Sheet) is available on request
