    Patent number: 4594384
    Abstract: The present invention relates to an adhesive composition for manufacturing glued laminated beams and wood constructions. One component of the adhesive composition is resorcinol-phenol resin. Resorcinol-phenol adhesives are as such known in the prior art. The main ingredients of these adhesives are resorcinol, formaldehyde and phenol.
