This article discusses the increasing environmental restrictions on wood products in outdoor environments, due to aging caused by climate factors such as light, water, and biodegradation. Traditional wood coatings are being phased out for safer alternatives like those made from vegetable oils and epoxy resins, which offer better compatibility with wood surfaces and higher crosslinking capabilities.
Environmental policies are becoming more restrictive in preserving ecosystems, encouraging the use of renewable resources such as wood. Wood products need to be protected, notably in outdoor situations, because wood is aging under the effect of climate conditions such as light, water and biodegradation. Surface color modifications occur, accompanied by a decline in physico-mechanical properties. Classical wood coatings are progressively prohibited due to their environmental toxicity, thus calling for safer coatings. Here we review wood photodegradation and protective coatings made of vegetable oils and epoxy resins. Epoxy resins allow high crosslinking and solve the common incompatibility of wood surface and coatings.
