HYPERDESMO®-C-LV
4Pages

DESCRIPTION HYPERDESMO®-C-LV is a one component, low viscosity, polyurethane fluid which cures with the humidity in the atmosphere to produce a highly elastic membrane with strong adhesion to many types of surfaces. It is based on pure elastomeric hydrophobic polyurethane resin plus special inorganic fillers, which result in excellent mechanical, chemical, thermal, UV and natural element resistance properties. Apply with brush, roller or airless spraying in two coats. Minimum total consumption: 1.5-1.8 COMPLIANCE - CERTIFICATION • CE: ETA-04/0082. See table below. • ASTM C 836/ C 836M -18 RECOMMENDED FOR Waterproofing and protection of: • gypsum and cement boards, • tiles (under), • bathrooms, • roofs, • light roofing made of metal or fibrous cement, • asphalt membranes. LIMITATIONS Not recommended for: • unsound substrates (in some cases, application is possible with the use of geotextile reinforcement; please contact our technical department for consultations). • waterproofing of swimming pool surfaces in contact with chemically treated water. When used in dark colours for exposed use, a protective topcoat of HYPERDESMO®-ADY-E (always pigmented at the desired colour) or HYPERDESMO®-ADY 500 is required. In order to maintain long-term solar reflectance and better colour protection, it is beneficial to apply the aforementioned topcoat layers even when HYPERDESMO®-C-LV is applied in light colours. FEATURES & BENEFITS • No thinning is required but SOLVENT-01 may be used. • Excellent weather and UV resistance. The white colour reflects much of the solar energy and so reduces the internal temperature of buildings considerably. • Excellent thermal resistance, the product never turns soft. Max service temperature 90 oC, max shock temperature 200 oC. • Resistance in the cold: The film remains elastic even down to -40 oC. • Excellent mechanical properties. • Good chemical resistance. • Non-toxic after full cure. • Water vapor transmission: The film breathes so there is no accumulation of humidity under the coat. 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, galvanized steel. For information about other substrates, please contact our technical department. Certified quality, environmental and occupational health & safety management systems: ISO 9001/14001 & ISO 45001.

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. 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 must be removed. Fill surface irregularities with appropriate product. Priming: Apply the required primer following the guidelines above. Mixing: Use a low speed (300 rpm) mixer. May...
