초록
In order to prevent decay, distortion, bending, twist on wood products such as woodenfurnitures, variety of coating materials were developed and used so far. The coating materialsfor wood finishing can be synthesized by natural resource or petroleum. However, thesecoating materials can cause contamination of indoor air quality due to emission of volatile organiccompounds (VOCs). In this study, commercialized coating materials for wood finishingsuch as varnish, coat, and stain were evaluated on emission characteristics of VOCs. Amongthe varnish, eco-friendly products had about 15∼46% lower TVOC emission (1,042 μg/m2h∼3,257 μg/m2h, respectively, than typical product (7,100 μg/m2h). Natural resource based coatingmaterial showed lowest TVOC emission level. However, one of natural resource based waterbornestain showed higher TVOC emission level because waterborne stain already containedhigher amount of natural VOC. Oil-based stain might not be suitable for indoor use on interiorwall and furniture due to exceed amount of TVOC. Based on results, natural resource basedcoat or waterborne stain are recommenced to use on wood products.
