Low-Temperature Durability of Common Wood Adhesives
Cyclic exposures of water-saturated Douglas-fir boards, laminated with various adhesives, under ambient (20?C), moderate-frigid (-12?C) and extreme-frigid (-65?C) conditions have shown urea-formaldehyde and phenol-resorcinol-formaldehyde adhesives to have a greater loss […]
