Parafoam Construct NBS

Parafoam Construct NBS is a single-component polyurethane foam designed for professional and experienced DIY applications. Its very low expansion pressure makes it ideal for sealing, insulation and joint filling, as well as for bonding light polystyrene and polyurethane insulation panels in interior applications, without risk of substrate deformation.

Technical specifications

• Single-component polyurethane foam with low expansion pressure
• Joint density: 15 to 19 kg/m³
• Compression strength: 50 N/cm² (on moistened surface)
• Tensile strength: 600 N/cm² with 22% elongation at break
• Minimal shrinkage: less than 1%
• Dust-free after 6 to 10 minutes
• Thermal resistance from -50°C to +90°C after curing
• Excellent adhesion to wood, concrete, brick, plaster, metal, polystyrene and polyurethane

Application advice

Apply the product at ambient temperature between 5°C and 30°C, ideally at 20°C. The temperature of the canister itself should be between 5°C and 25°C for optimal performance. Lightly moistening surfaces before application promotes curing and improves adhesion.

Use exclusively with an NBS applicator gun for precise dosage and optimal flow control. Once cured, the foam can be cut, sawn, skimmed and painted as required. Carry out a preliminary test on a small area to verify compatibility with your substrate.

The foam cures through reaction with ambient moisture. Allow sufficient curing time before finishing operations. The product contains no CFC or HCFC, respecting the ozone layer.
