Abstract
Ethyl acetoacetate as a formaldehyde scavenger in UF resins used to bond beech veneer. The study investigated the possibility of using acetoacetate groups to reduce the emission of formaldehyde from plywood glued with UF resin. Ethyl acetoacetate (in amounts of 5, 10 and 15%) was applied to the veneers, prior to the bonding process with UF resin, and then subjected to esterification at different temperatures (20, 40 and 60°C). Studies have shown that the use of acetoacetate groups enables significant, even a 66% reduction in formaldehyde emissions from plywood, in the case of esterification process at a temperature of 40°C.
