The formaldehyde to urea molar ratio (F/U) plays an important role on the properties of urea
formaldehyde (UF) resins and of the medium density fiber board (MDFs) bonded with them …

Recently, there has been a rapid growth in research and innovation in the synthesis of UF
resins in the wood-based composites area. Much effort has gone into increasing their …

In this study, the effect of the molecular weight (MW) of urea–formaldehyde (UF) resins on
their cure kinetics, interphase, penetration into wood, and adhesion strength was evaluated …

In this paper, the influence of initial formaldehyde/urea (F/U) molar ratios on the performance
of low molar ratio (1.0) urea-formaldehyde (UF) resin adhesives has been investigated. Two …

Urea formaldehyde resins were formulated with combination variables of three reaction pH
(1.0, 4.8, and 8.0) and four molar ratios of formaldehyde to urea (2.5, 3.0, 3.5, and 4.0). The …

Furfural, as an organic compound derived from biomass materials, was used to partially
substitute for formaldehyde in the synthesis of UF resin. Urea-formaldehyde-furfural co …

Urea‐formaldehyde (UF) resins are prone to hydrolysis that results in low‐moisture
resistance and subsequent formaldehyde emission from UF resin‐bonded wood panels …

Urea–formaldehyde‐bonded wood products are limited to interior nonstructural applications
because of their poor durability under cyclic moisture or humid environments. The stability of …

Urea-formaldehyde (UF) resin is one of the most widely used adhesives in wood-based
composites. The major concerns of the resin utilization are free formaldehyde release and …

Abstract Polymeric 4-4 diphenyl methane diisocyanate (pMDI) was blocked with an aqueous
sodium bisulfite solution to obtain water-dispersible blocked pMDI (B-pMDI) resin with …
