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 ...

New composite foams were prepared by co-foaming of Melamine-Urea-Formaldehyde (MUF) resin and wood fiber in the closed mould at 70°C. The effects of amount of wood fiber on mechanical properties, brittleness, flame-retardant, insulation and microscopic structures of wood fiber-MUF foam were investigated.

AbstractThe strength improvement induced by addition of acetals such as methylal and ethylal in melamine–urea–formaldehyde (MUF) resins could be mostly ascribed to the increased effectiveness and participation of the melamine to resin cross‐linking.

Reliable wood-adhesive bonds are crucial for future wood-biomass utilization. This ongoing research aims at systematically investigating interactions between adhesives and extractable wood constituents. The simultaneous examination of the progress of chemical reactions and changes in rheological properties of both pure adhesives and adhesive-extract ...

Poly(amidoamine)s dendrimers (PAMAM)s of different generations (Gn, where n = 1–3) were prepared via Michael addition/amidation reactions following a well-established procedure and their molecular weights were determined using matrix-assisted laser desorption ionization-time of flight (MALDI-TOF).

Particleboards production, which depends mainly on thermoset resins, e.g., such as melamine urea formaldehyde (MUF) and urea formaldehyde (UF), can result in subsequent liberation of the carcinogenic formaldehyde of the panel in service. This situation needs the substitution of formaldehyde with less active aldehydes.

MUF resin is widely used as an adhesive in wood industries, coating technology, paper industries and a main material in kitchenware production. In various applications, different resin properties are needed to suit its application. Important resin properties are for example higher resin solubility, low curing period with lower temperature and catalyst

In this study; changes in some properties of the okume plywood panels when used alder and beech veneers in their core layers were investigated. Two types of melamine-urea formaldehyde (MUF) resins having different free formaldehyde contents were used for bonding plywood panels manufactured from 2 mm thick veneers at industrial conditions.
