Melamine-formaldehyde resins modified with glycerol

, 2015
Melamine-formaldehyde resins represent an important class of aminoplastic resin and are made by the reaction of formaldehyde with mainly melamine. Melamine-formaldehyde resins are used as adhesives for plywood and particleboard for use in humid and ...

Simple urea-glutaraldehyde mix used as a formaldehyde-free adhesive: effect of blending with nano-Al2O3

, 2010
International audienceA formaldehyde-free adhesive based on urea (U) and glutaraldehyde (GA) was developed. High reactivity of the urea-glutaraldehyde mix at ambient temperature allows for its cold setting. The glues of GA/U molar ratio between 0.8 and 1.

Simultaneous confocal laser scanning microscopy (CLSM) observation of melamine–urea–formaldehyde resin and pMDI wood adhesives penetrating plywood

Journal of Wood Science
Abstract Wood absorbs carbon dioxide from the atmosphere, and by being converted into wood-based materials, stores carbon in the long term, thereby contributing to the mitigation of global warming. Wood production relies on adhesives, making a detailed understanding of the adhesive interface essential to ensure performance.

Melamine–Glyoxal–Glutaraldehyde Wood Panel Adhesives without Formaldehyde

, 2017
(MGG’) resin adhesives for bonding wood panels were prepared by a single step procedure, namely reacting melamine with glyoxal and simultaneously with a much smaller proportion of glutaraldehyde. No formaldehyde was used.
