Development of phenol-formaldehyde resin with low formaldehyde emissions that respects LEED certification

Thermal Degradation and Stability of Accelerated-curing Phenol-formaldehyde Resin

In order to study the thermal stability of accelerated-curing PF resin, the curing behavior of fresh PF resin was investigated in the presence of single accelerator of methylolurea derivatives (MMU), magnesium hydrate (Mg(OH)2), 25% aqueous solution of sodium carbonate (Na2CO3), and propylene carbonate (PC). Also their optimum combination was added in fresh PF resin. The thermal stability of cu...

Synthesis and low-potential electrogenerated chemiluminescence of surface passivated phenol formaldehyde resin@CdS quantum dots

A novel method for the synthesis of polymer-stabilized quantum dots (QDs) was reported through a onepot hydrothermal reaction. Using this method, a phenol formaldehyde resin (PFR) polymer was formed in situ to passivate the surface of the CdS QDs with hexamethylenetetramine as the source of both the monomer and the crosslinking agent, HCHO. The PFR-capped QDs possessed a uniform size distributi...

Effect of Modification with Phenol Formaldehyde Resin on the Mechanical Properties of Wood from Chinese Fir

Samples of Chinese fir were treated with either low-molecular-weight or commercial phenol-formaldehyde (PF) resins. The macroand micromechanical properties of the treated and untreated samples were determined. The average longitudinal tensile modulus of elasticity (MOE) was 30.88% larger for the samples treated with the low-molecular-weight PF resin than it was for the untreated samples. The av...
