Soybean meal‐based adhesive enhanced by MUF resin

Journal of Applied Polymer Science, 2012
AbstractSoybean meal flour, polyethylene glycol (PEG), sodium hydroxide (NaOH), and a melamine‐urea‐formaldehyde (MUF) resin were used to formulate soybean meal/MUF resin adhesive. Effects of the adhesive components on the water resistance and formaldehyde emission were measured on three‐ply plywood.

Colloidal aggregation of MUF polycondensation resins: Formulation influence and storage stability

Journal of Applied Polymer Science, 2003
AbstractColloidal particle formation followed by their clustering has been shown to be the normal way of ageing of aminoplastic resins, in particular melamine–urea–formaldehyde (MUF) resins. Ageing (or further advancement of the resin by other means such as longer condensation times) causes whitening of the resin.

Curing behavior of melamine-urea-formaldehyde (MUF) resin adhesive

International Journal of Adhesion and Adhesives, 2015
Abstract In this work, MUF resin was tested by DMA method. It showed that G ′ curves and strain curves together could be used to predict the curing behavior of MUF resins. The study showed that sequential formulation was preferred for the preparation of MUF resins. Hardener could accelerate the curing of MUF resins.

A13C-NMR analysis method for MF and MUF resins strength and formaldehyde emission from wood particleboard. I. MUF resins

Journal of Applied Polymer Science, 1996
A method based on the use of 13C-NMR relative peak intensity rations for different characteristic chemical groups, known or supposed to contribute to melamine-urea-formal-dehyde (MUF) resin strength and formaldehyde emission, is presented. The method relates results obtained by 13C-NMR analysis of liquid MUF resins with their strength and form aldehyde

A Soy Flour-Based Adhesive Reinforced by Low Addition of MUF Resin

Journal of Adhesion Science and Technology, 2011
The desire to prepare a lower-cost soy-based adhesive has led to an interest in using the abundant and inexpensive soy flour (SF) as a substitute for expensive soy protein isolates (SPI) in wood adhesives. However, the weakness of this adhesive is poor water-resistance and bonding strength due to a low protein content, which limits its application in ...

Effect of Melamine Content in MUF Resin on the Durable Properties of Plywood

Applied Mechanics and Materials, 2011
The effect of melamine content in melamine modified urea formaldehyde (MUF) resin on durable properties of plywood was investigated using ammonium chloride (NH4Cl) with different melamine/urea (M/U) ratios. The plywood specimens were exposed to laboratory accelerated aging and/or cyclic soak-dry (SD).
