Saint Gobain Mariseal 300 Liquid applied Polyurethane solvant free waterproofing membrane Mumbai

Service Details

Liquid-applied Polyurethane Waterproofing Membrane  Solvent-free  Product Description Advantages   MARISEAL 300 is a liquid-applied, solvent-free, hard-elastic, cold applied and cold curing, two component polyurethane membrane used for long-lasting waterproofing and protection.  Cures by reaction (cross linking) of the two components.   Tested for safe use in potable (drinking) water reservoirs by NSF  When applied forms seamless membrane without joints or leak possibilities  Resistant to cold water, warm water and frost  Maintains its mechanical properties over a temperature span of   -30oC to +90oC (not suitable for wet load over +60oC)  Remains elastic even at low (frost) temperature  Odor free  Full surface adherence  The waterproofed surface can be walked on  Main Uses Consumption   Drinking Water Tanks and Reservoirs (fully      Reinforced)   Drinking Water Supply Channels (fully      Reinforced)    Drinking Water Pipes  Swimming Pools (under tiles)    Packaging  MARISEAL 300 A+B is supplied in 6+1 kg and 15+2,5 kg metal pails. Pails should be stored in dry and cool rooms for up to 12 months. Protect the material against moisture and direct sunlight. Storage temperature: 5o-35oC.  Products should remain in their original, unopened containers, bearing the manufacturers name, product designation, batch number and application precaution labels.   2,0- 2,5 kg/m2 in more than two layers fully reinforced.  This coverage is based on practical application by roller onto a smooth surface in optimum conditions. Factors like surface porosity, temperature, humidity, application method and finish required can alter consumption.     Colours  MARISEAL 300 is supplied in off-white, blue and grey. Other RAL colours on demand. Due to the sensitivity of aromatic polyurethane to UV rays, the applied coating might yellow and fade on the surface. This change in appearance does not modify its mechanical properties or leak tightness.     Certifications   The MARISEAL 300 is tested according to the BS 6920:2000 by the NSF Laboratory in the United Kingdom, for use on surfaces in direct contact with potable (drinking) water, and potable (drinking) water storage tanks.  MARISEAL 300 is certified according to the Singapore Standard SS 375:2001 "Suitability of non-metallic products for use in contact with water intended for human consumption with regard to their effect on the quality of the water" and was found conforming.               Technical Data * PROPERTY  RESULTS Composition TEST METHOD Mixing Ratio  Polyurethane Resin + Hardener  A+B = 6:1 by weight  Resistance to Water Pressure No Leak (1m water column, 24h) Elongation at Break DIN EN 1928 >60% (without reinforcement) Adhesion to concrete ASTM D 412 >2,0 N/mm 2  Pot life  EN 1542 30min@20oC Hardness (Shore A Scale) 70 + 5 Inhouse Lab ASTM D 2240 Solids Content 100% UV accelerated ageing, in the presence of moisture CALCULATED Passed - No significant changes Hydrolysis (5% KOH, 7days cycle) EOTA TR-010 No significant elastomeric change Service Temperature  Inhouse Lab -30oC to +90oC (not suitable for wet load over +60oC) Tack Free Time 6-8 hours  Inhouse Lab Light Pedestrian Traffic Time Final Curing time (ponding test) 24 hours 7 days  Conditions: 20oC, 50% RH Chemical Properties Good resistance against acidic and alkali solutions (5%), detergents, seawater and oils.
