HYPERDESMO®-PB-2KTwo-component - 1:1, polyurethane (A): bitumen (B), by volume - liquid membrane for waterproofing & protection. DESCRIPTION FEATURES & BENEFITS 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 polymerised virgin bitumen. Apply with brush, roller, spatula or airless spraying. Minimum consumption: 1.5 lt/m2. COMPLIANCE - CERTIFICATION • CE: ETA-10/0095 • ASTM C836-95 • root resistance RECOMMENDED FOR Waterproofing and protection of: • basements, • foundations, • roofs (inverted roof insulation build ups), • green roofs and flower pots, • gypsum and cement boards, • polyurethane insulation foams, • asphalt membranes, • bathrooms (under tiles), • verandas and balconies (under tiles), • light roofing made of metal or fibrous cement, • non-potable water tanks, • bridge platforms, • "cut-and-cover" tunnels, • irrigation channels. LIMITATIONS Not recommended for unsound substrates or UV-exposed applications. • 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/steel reinforced concrete or otherwise, 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%.
