Title: Effect of synthesis variables on tack in urea-formaldehyde resin

Author: Leicht, R.J.; Hse, C.Y.; Tang, R.C.;

Date: 1988

Source: Journal of Adhesion 25:31-44

Publication Series: Miscellaneous Publication

Description: The degree of tack-the ability of resin to adhere to another surface under light pressure and over short time- in urea-formaldehyde resin varies throughout the particle board manufacturing process and affects mill maintenance and board quality. A three-part study was conducted to evaluate the effects of certain synthesis variables- molar formaldehyde:urea ratio, ingredient concentration, reaction pH, and reaction catalyst- on tack of urea-formaldehyde resin in particle board manufacturing. Southern pine particleboard mats were formed and prepressed in the laboratory, and tack was evaluated with the push-off method. Reaction pH significantly affected tack and viscosity, which were highly related.

Keywords: Particleboard, reaction catalyst, reaction pH, tack, urea-formaldehyde resin, effect of resin-synthesis variables
