DescriptionImproving the exterior quality bonding of wood to epoxy adhesive resins is important for bonding glass-fiber-reinforced vinyl ester resin laminae to glulam structural members, as well as for repairing glulam members in exterior applications on site. The coupling agent for these applications, hydroxymethylated resorcinol (HMR), was recently improved by using a novolak version (n-HMR) to reduce reaction time. In this study, the chemical composition of HMR was changed to decrease the total amount of formaldehyde added to the system. The results showed that n-HMR can be applied to a wood surface and stored for up to 16 days without compromising its effectiveness as a coupling agent.
