Influence of preparation parameters on the CHT curing diagrams of MUF polycondensation resins
Journal of Applied Polymer Science, 2001AbstractLignocellulosic substrates such as wood have been found to have a marked modifying influence on both lower‐temperature and higher‐temperature zones of TTT and CHT diagrams during hardening of formaldehyde‐based polycondensates. While the modifying influence of the substrate has been described, the modifying influence of some of the most ...

AbstractAcetals such as methylal and ethylal are shown to be particularly effective additives in improving the strength of wood boards bonded with melamine‐ urea‐formaldehyde (MUF) resins, although they show some appreciable but lesser effect on other resins too, particularly phenol‐ formaldehyde resins.

Abstract Melamine-urea-formaldehyde (MUF) resins are commonly used in the production of wood-based panels. The composition of the resin influences many properties of the final product. In industrial production, some properties, such as viscosity, pH, solid content, or molar ratio, are assessed after resin production in order to evaluate if they are ...

Abstract Natural fibers have lot of merits over other established materials as reinforcement which recently attracted the attention of researchers. They are environmentally-friendly, fully biodegradable, abundantly available, easily accessible, non-toxic, non-abrasive, renewable, cheap, and have low density.

Evaluating the wettability of MUF resins and pMDI on two different OSB raw materials
European Journal of Wood and Wood Products, 2013In this paper, the wettability of two different wood species as raw material for Oriented Strand Board (OSB) is analyzed. One species is pine, a common material for the production of OSB; the other species, poplar, and especially hybrid poplar, is newly used in OSB and might require a modified board production process compared to pine.

AbstractIminoamino methylene bases intermediates are obtained by the decomposition of hexamethylenetetramine (hexamine). These are stabilized by the presence of strong anions such as SO and HSO, that is, “hexamine sulfate.” The effect of hexamine sulfate was closely linked to the strong buffering action it has on MUF resins.

AbstractA new sulfonated melamine–urea–formaldehyde (MUF) resin of relatively low melamine content, prepared according to a sequential formulation, has been shown to be highly effective when coupled with different natural vegetable tannins to produce leather with the same good characteristics of leather prepared with chrome salts.

Poor performance of PMUF adhesives prepared by final coreaction of a MUF with a PF resin
Holz als Roh- und Werkstoff, 1996Investigation of the performances of phenol-melamine-urea-formaldehyde resins prepared by final coreaction of a MUF with a PF resin. These resins were used to prepare plywood glue-mixes.
