Märkäpinnoitus

Märkäpinnoitus, or wet coating, is a general term for applying a coating material in a liquid or slurry form onto a substrate. This process involves a liquid carrier that evaporates or cures, leaving behind a solid film. Märkäpinnoitus encompasses a wide range of techniques and materials used in various industries.

Common methods include dipping, spraying, brushing, and rolling. The choice of method depends on the substrate's shape, size, and the desired coating thickness and finish. Materials used in märkäpinnoitus can include paints, varnishes, lacquers, enamels, and specialized functional coatings. These coatings can provide decorative, protective, or functional properties, such as corrosion resistance, insulation, or improved surface characteristics.

The substrate is typically prepared before coating to ensure good adhesion. This preparation might involve cleaning, degreasing, or surface roughening. After application, the coating often undergoes a drying or curing process, which can involve air drying, baking in an oven, or exposure to UV light, depending on the coating's chemistry. Märkäpinnoitus is a versatile and widely used method for surface treatment and finishing in manufacturing, construction, and artistic applications.
