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.
