Abstract
The invention consists of the copolymer resin compound containing the amino group consisting of polyflavonoid and its derivative compounds, amino compounds (urea, monomethylol urea, dimethylolurea, etc.), formaldehyde and stabilizer agents. The shelf life of the produced copolymer resin composition is 1 to 2 months at 18-20° C. The invention is about the said resin's ability to reduce the formaldehyde level of the wood-based composite products without sacrificing board's performance (physical, mechanical testing) values.
