Abstract
Waxy hydrocarbyl substituted phenols or phenates are reacted into phenol formaldehyde resins to impart a waxy water resistant nature to binders. A preferred use of the modified phenol formaldehyde resins is as a binder in engineered wood products such as strand board, particle board, medium density fiberboard, plywood and I-beams. Binding the waxy material into the resin may provide a better dispersion of the waxy moieties and prevent migration as has been seen by the simple addition of waxy materials.
