Abstract
Lowering of formaldehyde emission from modified UF resin with collagen polymers. Presented work describes the possibility of lowering the formaldehyde emission from wood products glued with ureaformaldehyde (UF) adhesive. Results of laboratory tests confirmed, that collagen prepared from leather waste is suitable additive for lowering of formaldehyde emission from wood products glued with UF adhesive. Increased efficiency of collagen was obtained by modification with urea and di-aldehyde. Tests confirmed the decrease of formaldehyde content in comparison with the standard down to 50 % stated by perforator method.
