Wood coatings Painting

Wood is painted in order to preserve from decay, to minimize changes in moisture content that lead to distortion, and for decoration. It is a waste of time and effort to apply expensive paints or stains to exterior wood not previously treated with preservative. Preservatives are designed to penetrate the timber to protect against microorganisms and insect attack. Modern preservatives can be over-coated with paint without problems. 

At present, systems cured by ultraviolet light or electron beams [12-14] are used primarily in wood coatings, which contain very little or no pigment they are employed to a lesser extent in paper coating and other applications. In contrast to the printing field, the comparatively thick layers in which paint systems... 

Butyl acetate [123-86-4], one of the more important derivatives of -butyl alcohol produced commercially, is employed as a solvent in rapid drying paints and coatings. In some instances, butyl acetate, C.H1202, has replaced ethoxyethyl acetate [111-15-9] due to the latter s reported toxicity and teratogenicity. Butyl acetate is used in leather treatment, perfumes, and as a process or reaction solvent and is also used extensively with wood coatings, maintenance coatings, and in coatings for containers and closures. 

BASF s BASIL process [15] and the Dimersol process [16] have both been commercialized. The former uses the ionic liquid as a phase transfer catalyst to produce alkoxyphenylphosphines which are precursors for the synthesis of photoinitiators used in printing inks and wood coatings. The imidazole acts as a proton scavenger in the reaction of phenyl-chlorophosphines with alcohols to produce phosphines. The Dimersol process uses a Lewis acid catalyst for the dimerization of butenes to produce Cs olefins which are usually further hydroformylated giving C9 alcohols used in the manufacture of plasticizers. Several other processes are also at the pilot plant scale and some ionic liquids are used commercially as additive e.g. binders in paints.

Previous research on acid deposition effects on wood coatings did not take into account the effect of the substrate but linked poor performance in acid environments to the extenders in the paint. It should be relatively easy to formulate paints to overcome this erosion problem. However, in wood it is catastrophic failure that causes most poor-paint performance. Thus, the effect of acids on this interface failure should be addressed in future work.
