pinnoitetuissa

Pinnoitetuissa is a Finnish term used in technical and everyday language to describe items or surfaces that have been covered with a surface coating. The word comes from pinnoite, meaning coating or finish, and the participial form pinnoitetuissa conveys “in coated [things]” or “with coatings.” In Finnish texts, this form is common when referring to products or materials that bear a protective or functional surface layer.

Coatings are applied for various reasons, such as protection against corrosion, wear, or moisture, and to create specific functional properties like non-stickness, low friction, or aesthetics. In household contexts, many cookware items are described as pinnoitetuissa when they have non-stick or ceramic coatings. Industrially, metal parts, machinery, and fasteners may be pinnoitetuissa to extend service life, reduce maintenance, or improve appearance. In electronics, conformal coatings are applied to circuit boards to protect against moisture and contaminants, a usage that can also be described with the term in Finnish texts.

Common coating types referenced in Finnish information include non-stick PTFE (and PFAS-free variants), ceramic coatings, epoxy and polyurethane coatings, and powder coatings for metals. The choice of coating depends on factors such as temperature tolerance, chemical resistance, durability, safety, and compatibility with the base material.

Care and safety considerations are often noted in product labels and manuals. Coatings may degrade under extreme heat or abrasion, and some coatings require specific cleaning methods to preserve their properties.
