Coating wood surfaces first by delignification followed with a transparent varnish

摘要

A method of coating wood comprising photo stabilising a surface of the wood using delignification of the surface including removal/destruction of photo absorbent lignin fragments, and subsequently coating the surface with a transparent coating. Suitable delignification agents include chemical delignifying agents, lignin-degrading radiation and lignin-degrading enzymes. Suitable delignification agents include peracetic acid or peroxymonosulphuric acid. The figure shows an FTIR spectrum for a peroxymonosulphate-treated sample and a control sample of wood where delignification is evidenced by removal of the 1510 wavenumber band.
