The infrared spectra of liquid and solid films of
formaldehyde were taken over the range of 35 to 4,000 cm⁻¹
using Beckman IR 7 and IR 11 spectrometers. A new overtone
band and a new combination band were found as well as three
fundamental peaks due to lattice vibrations and...
It was the goal of this research to determine if sago
starch could be used to replace wheat flour as an adhesive
extender of Urea-formaldehyde plywood adhesives through
either chemical modification of the starch or modification
of the adhesive formulation strategy. Guiding principles of
the research would be that a...
Synthetic adhesives, such as phenol-formaldehyde (PF) resins and urea-formaldehyde (UF) resins, have dominated the wood adhesive market since they were introduced in the wood products industry. Formaldehyde, as a key component in the manufacturing of PF and UF resins, has been classified as a known human carcinogen by the International...
