ABSTRACT:
Disclosed are a new adhesive and a process for making wood laminates with the adhesive. In a preferred embodiment, the adhesive will comprise a phenol-formaldehyde condensation product having a molar ratio of phenol to formaldehyde in the range of 1:1.5 to 1:2.5, a sodium hydroxide catalyst, and from 5 to 50% bentonite clay based upon the phenol-formaldehyde condensation product solids. The preferred process employs the new adhesive to prepare laminates using high moisture content veneers, such as southern pine. The laminates exhibit average percent wood failures of from 85 to 98%.
