Synthesis and characterisation of one-part ambient temperature curing polyurethane adhesives for wood bonding

The effects of polyol types, polyol molecular weights, NCO/OH molar ratio, solvent types, and resin solid contents of the one-part ambient temperature curing adhesives were studied. The results showed that the one-part ambient temperature curing polyurethane prepared had fast rate of setting and good bonding, meeting the requirements of a typical structural adhesive.
