Abstract
When working with wood, coatings suited to the intended end-use application are employed. In wood with a porous structure, the paints penetrate the wood, influencing the weatherability and colourability of the wood. Roughly sawn texturing and laser micro incising were studied as methods to increase paints penetration into wood. This study investigated linseed oil penetration when applied to sugi wood subjected to plasma treatment, which is a widely used technique in microfabrication and surface modification. The results showed that the weight percentage of linseed oil that penetrated wood specimens was comparatively higher for samples that had been plasma treated for 30 minutes or 120 minutes compared to the untreated wood samples. For all of the treatment conditions, linseed oil penetration depth was deeper for latewood than earlywood, and linseed oil penetrated deeper into plasma-treated wood than into untreated samples.
