Lihvimiskatteid

Lihvimiskatteid are coatings applied to surfaces that have been or will be polished, with the aim of improving gloss, protection, and surface uniformity. The term is used in Estonian industry to describe finishing coatings across several sectors, including metalworking, woodworking, automotive refinishing, jewelry, and electronics assembly.

Formulations vary but commonly include waxes, oils, resins, and polymer films. Some coatings are solvent- or water-based emulsions that cure by evaporation, while others form hard films through heat or UV curing. The choice depends on substrate compatibility, desired appearance, and expected wear.

Application methods include wipe-on, spray, brush, or film deposition, often followed by buffing or polishing to achieve a uniform, high-gloss surface. In many workflows, the coating also serves to fill micro-scratches and reduce the need for subsequent polishing steps. Durability depends on hardness, abrasion resistance, chemical resistance, and UV stability.

Limitations can include residue buildup, yellowing or haziness with some formulations, and difficulties in removal. Environmental concerns focus on volatile organic compounds and worker exposure, with industry trends moving toward low-VOC, water-based, or easily removable coatings.

Because the term is used in Estonian contexts, its precise meaning can vary by industry or application. In general, lihvimiskatteid refer to finishing coatings applied after polishing to enhance gloss and protect the surface.
