Abstract
A hardener composition and pine bark tannin-containing resin composition are disclosed. The resin composition is formulated to neutral pH in order to reduce the extent of self-polymerisation and provide a satisfactory shelf life. The hardener composition may be mixed with a suitable resin, or the resin composition mixed with a suitable hardener to produce a cold set adhesive which is particularly useful for bonding wood.
