Impacts of phenol formaldehyde (PF) and melamine urea formaldehyde (MUF) adhesives strengthened with nano chemilas on screw withdrawal strength of laminated wood elements

open access: yes
The aim of this study was to determine the effect of SiO2 and TiO2 modified phenol-formaldehyde (PF) and melamine-urea formaldehyde (MUF) glues and nanoproducts on radial, tangential and perpendicular screw withdrawal strength of wood laminates. For this purpose, LVL and GLULAM materials were obtained by gluing the test specimens arranged from Uluda ...

Influence of curing temperature on the bonding strength of heat-treated plywood made with melamine-urea-formaldehyde and phenol–formaldehyde resins

open access: yes, 2019
Melamine-urea-formaldehyde resin (MUF) and phenol–formaldehyde resin (PF) were prepared in the laboratory. Their curing behavior was analyzed by differential scanning calorimetry (DSC). MUF resin was then cured at 110, 120, and 130 °C, while PF resin was

Improving Hot-Water Resistance of Melamine-Urea-Formaldehyde by Addition of PolyFox PF-151N Polymer

open access: yes, 2013
International audienceMelamine urea formaldehyde (MUF) thermosetting wood adhesives have poor performance at elevated temperatures and humid conditions. PolyFox PF-151N polymer was mixed at different loadings (0.05, 0.1, 0.5, and 1%) with MUF to improve ...

Determination of formaldehyde/urea molar ratio in amino resins by near-infrared spectroscopy

open access: yes, 2011
New processes for synthesis of urea-formaldehyde (UF) and melamine-fortified urea-formaldehyde (mUF) resins have been developed in the last years, motivated by the current concerns about the effects of formaldehyde on human health. All these formulations

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

open access: yesJournal of Wood Science
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.
