Performance of MUF honeymoon adhesive for glulam
Résumé
Glulam beams were prepared using pine boards glued together with a melamine-urea-formaldehyde (MUF) adhesive by means of an experimental fast-setting process called ``honeymoon''. In this process, MUF is spread on the face of the first part, then an acid is spread on the face of the second part and the two are assembled. Mechanical properties of the beams remain very good even after severe water exposure in a delamination test. Moreover, the short pressing time of this honeymoon process (the adhesive is perfectly hardened after 3 h) makes it perfectly suitable for industrial applications.
