Effect of different hardeners for urea-formaldehyde resin on properties of birch plywood / Pavlo Bekhta ... [et al.]. -- Graf., tab. -- Lit. - The effects of various types of hardeners (aluminium sulphate, ammonium persulphate, ferrum chloride and combined hardener) on formaldehyde emission, shear strength and characteristics of urea-formaldehyde (UF) adhesives for the manufacture of plywood were investigated. Formaldehyde emission was determined using gas analysis method. The experimental results showed that addition of aluminium sulphate or ammonium persulphate to UF resin effectively reduced the formaldehyde emission of birch plywood down to 10-36 % without diminishing its shear strength.
