In this presented work, we describe the development and characterization of a new, environmentally friendly adhesive derived from cornstarch and tannins. The production of wood composites mainly relies on the petrochemical-based and formaldehyde-based adhesives such as urea formaldehyde (UF), phenol formaldehyde (PF) and melamine urea formaldehyde (MUF), which can generate under certain conditi...

Low mole ratio urea-melamine-formaldehyde (UMF) resins synthesized with 2.5% and 5.0% melamine levels added at the beginning, middle, and end points of the first alkaline step of the typical urea-formaldehyde (UF) resin synthesis procedure were compared with typical UMF resins synthesized with melamine additions made at the final alkaline step. Various resin analysis, particleboard preparation,...

Life-cycle inventory (LCI) data are needed to scientifically document the environmental performance of formaldehyde-based resins used in the manufacture of wood composite products. The resin data are needed by others to conduct LCI studies of wood composites when providing performance data for applications as governed by the many green building standards, purchasing guidelines, and energy and c...

The development of natural-based adhesives is a key aspect in reducing the consumption fossil resources, adapting to legislation on use formaldehyde and ensuring sustainability wood panel industry. This study focuses five alternatives for tannin-based (tannin-paraformaldehyde, tannin-glyoxal, tannin-hexamine, tannin non-isocyanate polyurethane (NIPU) with ammonium hydroxide NIPU HDMA bio-adhesi...

Abstract Chestnut bur is an agro-waste material generated in the chestnut production. It a tannin-rich lignocellulosic which might be promising raw for low-formaldehyde composite particleboard production when using urea–formaldehyde (UF) as bonding adhesive. In this study, characteristics of were analyzed to assess its application value panel. Five-type particleboards manufactured from mixture ...

The objective of this study is to evaluate the effect of décor paper and resin type on physical properties, mechanic properties, and surface quality properties of particleboards coated with décor papers impregnated by using different resin. White oak, New wenge and common maple pattern decor papers impregnated with urea formaldehyde (UF), melamine formaldehyde (MF) and urea-melamine formaldehyd...
