CHRYSO®ELASTOTHANE
CHRYSO ELASTOTHANE is a single component, bitumen / coal tar free high solid content liquid applied elastomeric polyurethane resin based cold applied coating system. Ideally suited for waterproofing of roofs, terraces, walls, basement conforming to ASTM C-836 95 & ASTM C – 898-95
Precautions
- Store the material at the 2° to 35°C temperature range in shaded cool place and keep it away from fire and any heated body. Clean all tools with MEK or any standard solvent before polymerization starts.
- Do not apply coating thickness more than 500 microns in one go. If the total coating thickness is more than 500 microns apply in multiple layers.
- Do not keep left over material in open condition and use it within 2-4 hours.
- Dot not apply the coating if the rain is expected within 24 hours.
Advantages
- Can be applied by brush or roller
- Being viscous it does not sag when applied on vertical surfaces. CHRYSO ELASTOTHANE has excellent adhesion to dry as well as primed surfaces of concrete, tile, plaster, bituminous roofing felt, asphalt coating and metal.
- Cured membranes of CHRYSO ELASTOTHANE remain highly flexible even at extremes temperature range (-25°C to 120°C).
- On drying CHRYSO ELASTOTHANE forms a seamless protective and waterproof membrane.
