Product Description
HA Safefoam NF is a phthalate-free, 1-component low-viscosity, hydrophilic polyurethane resin. After curing, HA Safefoam NF forms an inert, flexible foam with closed cell structure and very good tensile strength and adhesion. HA Safefoam NF can be used as a 2-component system with a ratio with water of 1/1 for the injection of dry cracks.

Benefits:

• ADR free transport
• Phthalate-free resin, REACH compliant
• Solvent-free
• TDI free
• Not flammable
• Very good adhesion and tensile strength
• Withstands thermal movements, wet / dry cycles, freeze / thaw cycles and joint movements without degradation of the material.
• Good general chemical resistance. (*)
