Fast-Setting Phenolic and Tannin-Based 'Honeymoon' Adhesive Systems for Exterior Grade Glued Laminated Timber
Glued laminated sample beams have been made using two commercially available fast-setting 'Honeymoon' adhesives. With these systems only two hours clamping time is sufficient to produce block shear strength results, under compression, in excess of the value required by the South African Bureau of Standards specification for glued laminated timber structural members. After seven days, the bond is sufficiently cured to meet the strength and wood failure requirements after 24 hours soaking in cold water and six hours in boiling water. The use of this system of adhesion, however, will involve changes to the current method of adhesive application and clamping in industry.
