Materials Used in Varnish and Wood Coatings and a Variety of Microscopic Techniques to Identify Them

Surface coatings protect wooden structures against weathering and other caries such as moisture absorption and microbial degradation. The efficiency and productivity of coatings depend on many factors, including the proper bonding of the coatings to the wood. Wood adhesion requires chemical and physical bonds between wood coatings and textures. Today, the increasing importance of hygiene, safety and environmental requirements in industrial production requires manufacturers to produce green coatings such as water-based coatings, powder coatings, high-density coatings, and coatings. It is radiation resistant due to the reduction of VOC emissions. Nowadays, modern coatings utilize nanotechnology (silicon dioxide nanoparticles, titanium dioxide and other compounds such as zinc oxide, silver ion) to improve the surface finish of wood. New coatings require the use of special materials and methods such as selegel, plasma and infrared powder coatings. Modern wood coatings include features that cannot be achieved with good or ideal coatings with conventional and past coating materials, so identifying new coating materials and methods It is very important in today's world.This study focuses specifically on advances made in understanding the physical aspects of contact surface using common surface and coating survey using high-resolution imaging techniques, including concurrent microscopy (CLSM) imaging. The scanning electron microscope will be the coordination and relevance of optical microscopy studies using confocal microscopy and scanning electron microscopy.
