A new line of polyurethane adhesives that do not contain mercury are recommended for assembly of thermoplastic components and other parts aimed at the global marketplace that is governed by new, strict environmental regulations. In the past, mercury catalysts have been used in PUR to promote curing. New mercury-free Araldite 2041-1 and 2042-1 from Huntsman Advanced Materials, The Woodlands, Texas, reportedly are fast setting, with open times of 2.5 to 12 min, and attain handling strength after 6 hr at 77 F. They bond PC, ABS, nylon, and Metton DCPD liquid molding resin with minimal surface preparation. Colored black, these adhesives are supplied in cartridges with a 1:1 mix ratio. Once cured, they boast good flexibility with elongation of about 250% and lap shear strength of up to 2100 psi on primed aluminum panels. Tel: 888-564-9318 . www.huntsman.com/ advanced_materials
