4. Paint and varnish degradation on wood and wood derivatives
4.1 Damage caused by the chemical characteristics of the woody substrate
4.1.1 Wood containing antioxidants
These are mainly Iroko and certain Doussiés. The antioxidants they contain prevent alkyd and glycerophtalic paints, and all "greasy" paints, from drying by siccativity. It is therefore necessary to apply at least one primer coat that dries by a mechanism other than siccativity. It should be remembered that the hardening of alkyd paints by siccativity is an oxidation of the binder's double bonds with an increase...
