Rattan Cane Modified with Polyethylene Glycol Melamine-Urea-Formaldehyde Resin

To effectively improve the strength of Plectocomia pierreana rattan cane without reducing its toughness, the cane was impregnated with a new water-soluble melamine-urea-formaldehyde (MUF) resin modified with low-molecular-weight polyethylene glycol (PEG), marked as PMUF. The PMUF synthetic process was optimized using an orthogonal test L9(3). Results showed that the dimensional stability, densi...

Melamine-modified urea formaldehyde resin for bonding particleboards

For the development of a cost-effective melamine-modified urea formaldehyde resin (MUF), the study evaluated the effects of reaction pH and melamine content on resin properties and bond performance of the MUF resin adhesive systems. Eight resins, each with three replicates, were prepared in a factorial experiment that included two formulation variables: two reaction pHs (i.e., 4.5 and 8.0) and ...

Resorcinol-Formaldehyde (R-F) Resin

studying thermal behavior and formaldehyde emission of modified urea formaldehyde resin by furfural

there are adequate sources for wood adhesives, but scarcity of oil resources can affect the cost and future availability of oil based resins. for avoiding of this process, seeking for feasibility of replacement of these oil feedstocks is necessary. in present work, thermal behavior of urea formaldehyde resin modified by furfural was investigated. the thermo-gravimetry was used for this purpose,...
