The Woodlands, Texas - Huntsman Advanced Materials has launched a new range of mercury-free polyurethane adhesives.
The Araldite rapid-setting adhesives are designed for bonding polycarbonate, ABS, nylon and liquid moulding resin with minimal surface preparation, the company said in a statement.
''The adhesives cure fast, attaining handling strength after six hours at 77oF (25oC),'' Huntsman said.
''Once cured, the mercury-free polyurethanes exhibit good flexibility with an elongation of approximately 250 percent and lap shear strength of up to 2100 psi on primed aluminium panels at room temperature.''
Black in colour, the Araldite 2041-1 and 2042-1 polyurethanes will be packaged in 50 ml and 200 ml double-barrel cartridges, as well as in a 250 ml universal cartridge with disposal nozzles.
The Araldite AW 8680/Hardener HW 5541-1 and AW 8680/Hardener HW 5542-1 polyurethanes will be supplied in bulk packaging.
