IMPERMAX POLYUREA H FLEX Sprayed, hot-applied polyurea waterproofing membrane DESCRIPTION Keep between 10º y 30ºC. Product is hygroscopic: protect from moisture. Component B may become hazy upon storage at low temperatures. Reheat Impermax Polyurea H Flex is a 2-component polyurea resin, which cures very fast into an elastic membrane with crack-bridging capacity. This product can only be applied by 2-component spraying equipment. Impermax Polyurea H Flex can be combined with different geotextiles to obtain on-site applied, mildly before use. Use before 12 months after manufacture, provided it is kept in its sealed container. seamless liners (Rayston Spray liners). It can be also pigmented with aluminium particles pigments to obtaing sun-reflective properties. INFORMATION ON THE FINAL PRODUCT Final state Waterproofing of concrete structures Polyurea H Flex can be completed with an coating. Solid elastomeric membrane Variable, depending on the chosen pigmentation. For colours available, please contact Krypton Chemical. Also possible addition of aluminium containing pigments for sun reflection effects. additional UV-resistant Roof waterproofing. Hardness (Shore) Geomembrane lining for retntion Tear strength basins and secondary containment structures, ponds, landfills, tunnels, canals, dam reparations, etc. Tensile strength: 15 MPa (EN-ISO 527-3) Additional UV protection can be achieved by application Fire test B2 (DIN 4102-1:1998): Ignitability when subjected to direct impingement of flame. Class B2 ETA: European Technical Assessment document Nº 21/0740 (EAD 030675-00-0107) – CE marking Good resistance to UV-induced degradation. Aromatic polyureas undergo change of colour under sunlight. of a Impertrans or colodur topcoat. Static indentations Liners obtained by combination of Impermax Polyurea H Flex and selected geotextiles achieve a static indentation resistance above 3200 kN (UNE EN ISO 12236:2007) Fire resistance Water vapour permeability TECHNICAL DATA INFORMATION ON THE PRODUCT BEFORE APPLICATION Chemical description Aromatic isocyanate prepolymer decomposition temperature (TGA test) Impact strength Physical state Packaging Non-volatile content Lead content Flash point 24,5 N x m, Class III > 20 N x m (EN ISO 6272-1) Permanent contact (7 days, 80ºC, 0=worst, 5=best) Chemical Water Ammonia (3%) Hydrochloric acid 3M (9%) Isopropyl alcohol Xylene Viscosity (mPa.s) Viscosity (mPa.s) Sulphuric acid (50%) Urea Density and viscosity of the mixture Does not break or crack (EN-495-5) Chemical resistance Dark yellow (may darken along storage) Abrasion resistance Fast polymerization. See Pot life data. Dark yellow, but component A is pigmented by addition of pigment paste (Pigment Spray) for Impermax Polyurea H Flex. Ammonium nitrate Adhesion Adhesion strength Concrete (EP 100) Steel (PU primer) SUPPORT REQUIREMENTS To achieve a good penetration and bonding, support must be: 1.Flat and levelled. 2. Compact and cohesive (pull off test must show a minimum resistance of 1,5 N/mm2). 3. Even and regular surface. 4. Free from cracks and fissures. If any, they must be previously repaired. 5. Clean and dry, free of dust, loose particles, oils, organic residues, or laitance. KRYPTON CHEMICAL SL C/ Martí i Franquès, 12 - Pol.

Relative air humidity should Solvent use for machine component cleaning is discouraged. A cleaning plasticizer fluid is suitable. Component B must be completely removed from all air-exposed parts and replaced with cleaning fluid. SUPPORT PREPARATION Concrete substrates must be prepared mechanically using high pressure sand or abrasion, to remove the surface and obtain an open pore. Substrates must be primed and...

Treat empty containers as hazardous waste and transfer them to an authorized waste manager. If the contains still have some material left, do not mix with other product with no knowledge of potentially dangerous reactions. Component A and B may be mixed on a 1/1 ratio to get an inert material, but never do it in volumes larger than 5 liters to prevent a dangerous heat evolution. OTHER INFORMATION The...
