Abstract

Effect of wood preservatives (waterborne and organicborne) on the performance of surface finishing properties is investigated. Sapwood of scots pine, (Pinus sylvestrisL.), oriental beech (Fagus orientalisLipsky), and chestnut (Castanea sativaMill.) specimens (300 × 100 × 15 mm along the grain) were impregnated with aqueous solution of 2% CCA, 2% Tanalith E, 1% boric acid, and Immersol aqua. Surface roughness, dry film thickness, adhesion strength, gloss measurement, scratch, and abrasion resistance were determined according to related standards for treated and untreated samples. The results indicated that surface roughness and adhesion strength depended on wood species and the chemical composition of preservatives. Generally, waterborne wood preservatives increased the surface roughness of wood while the organic-based wood preservatives decreased it. The organic-based wood preservatives decreased adhesion but they increased gloss value. Wood preservatives did not affect the scratch resistance which was found to depend on properties of the coating. All the wood preservatives increased abrasion resistance.

Highlights

Wood and wood-based materials have gained extensive usage areas in outdoor and indoor applications due to their abundance and versatility

This study dealt with the effect of wood preservatives on the performance of finishing

Summary

Introduction

Wood and wood-based materials have gained extensive usage areas in outdoor and indoor applications due to their abundance and versatility. Commonly used in outdoor applications, is preferred for proper protection and best service life against decay (rot), insects, weathering, and dimensional instability [1, 2]. The effect of wood weathering is manifested by initial wood surface colour changes, followed by loss of gloss, roughening, and checking [1, 3]. These changes are due to modification of chromophoric groups of wood and formation of coloured quinines-like component [1, 3, 4]
