A one-component, phthalate-free, hydrophilic polyurethane resin with low viscosity.
Once cured, HA Safefoam NF forms a chemically inert, flexible closed-pore foam with very high tensile strength and adhesion to substrates, including wet substrates.
HA Safefoam NF can be used in a 2-component system with a 1:1 mixing ratio with water for injection into dry cracks and joints.
Application:
– As a 2-component system for sealing dry, moving, non-structural cracks with a mixing ratio of resin and water as the second
component of 1:1,
– as a 1-component system for sealing wet, moving, non-structural cracks,
– sealing of leaking joints between tunnel segments,
– curtain injection behind tunnel segments,
– sealing of moving, leaking cracks.
Properties:
– transport is not subject to ADR regulations,
– phthalate-free resin, REACH-compliant,
– non-flammable,
– high adhesion and tensile strength,
– resistance to thermal displacement, dry-wet changes, freeze-thaw cycles and crack movements, without risk of degradation,
– good overall chemical resistance.
