HYPERDESMO®-POLYUREA-2K-HCTwo-component, sprayable, hot-cure polyurea for waterproofing & protection. DESCRIPTION HYPERDESMO®-POLYUREA-2K-HC is a two-component polyurea system, composed of 100% solids, for application by plural component spraying equipment. It is elastic and has a polymerization profile specially formulated for enhanced adhesion. It is highly recommended for commercial and industrial applications that require high levels of abrasion resistance and impact strength. The product is also available in a highly elastic version under the name of HYPERDESMO®-POLYUREA-2K-HC ELASTIC (see below properties table). Minimum total consumption: 1.5-2.0 kg/m2. RECOMMENDED FOR Sealing of cementitious surfaces. Waterproofing and protection of: • PU and polystyrene insulation foam, • Floors (HYPERDESMO-POLYUREA-2K-HC), • roofs, • tanks, • drinking water tanks (for this application please consult our technical department), • pipes. COMPLIANCE - CERTIFICATION CE: ETA 11/0016 liquid applied roof waterproofing kit Potable water tank waterproofing: UNE-EN 128731/2014 RD 140/2003 LIMITATIONS Not recommended for: • unsound substrates. Direct UV exposure requires the use of a topcoat to retain the colour. Recommended Topcoats: HYPERDESMO® ADY 810 HYPERDESMO® ADY-2K HYPERDESMO® ADY-E AQUASMART® TC 2K FLOOR PROTECT The selection of the final topcoat should be done based on the final use of the surface. Please see individual TDS of the above list or contact our technical department. FEATURES & BENEFITS • Quick curing - gel time 30 sec (unaffected by humidity and weather). • Bubble and defect free membrane. • No plasticizers. • No heavy metal toxic catalysts. • Excellent thermal resistance, the product never turns soft. Max service temperature 80 oC, max shock temperature 250 oC. • Resistance to the cold: The film remains elastic even down to -40 oC. • Excellent mechanical properties: High tensile and tear strength, high abrasion resistance. • Good chemical resistance. • Moisture vapor transmission: The film breathes so there is no accumulation of humidity under the coat. • Special primers are available for almost every substrate. APPLICATION PREREQUISITES Concrete substrate conditions (standard): • Hardness: R28 = 15Mpa. • Humidity: W < 10%. • Temperature: 5-35 oC. • Relative humidity: < 85%. Certified quality, environmental and occupational health & safety management systems: ISO 9001/14001 & ISO 45001.

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 must be removed. Fill surface irregularities with appropriate products. Priming: Apply the required primer following the guidelines above. Application: Drums of components should be pre-heated to 25° C prior to mixing or dispensing. In cold weather conditions, it is recommended that the drums be...
