Prefere 4050 liquid resins mixed with hardener Prefere 5750, is a fully weatherproof adhesive system especially suited to the manufacture of large laminated timber structures. Prefere 4050 adhesives are also suitable for use in the production of heat resistant composite structures, eg fire-resisting doors and will give an excellent bond strength when bonding Accoya®.
For jointing applications, Aro-Bond 920 or 947 are the best option and have been extensively tested for bonding Accoya®. Aro-Bond 920 is a single component moisture curing polyurethane wood adhesive with excellent water resistant characteristics. Aro-Bond 920 meets the requirements of BS EN204 category D4 for water resistance.
