märkämaalit

Märkämaalit is a Finnish term that translates to "wet paints" or "wet finishes." It refers to coatings applied in a liquid state, such as paints, lacquers, varnishes, and stains, which require drying or curing before they achieve their final hard and protective properties. This broad category encompasses a vast array of products used for decorative and protective purposes across numerous industries, including construction, automotive, furniture manufacturing, and arts and crafts.

The application methods for märkämaalit are diverse and depend on the specific coating and surface. Common techniques include brushing, rolling, spraying (air, airless, electrostatic), dipping, and flow coating. The effectiveness of these methods is influenced by factors such as viscosity, surface tension, and drying time of the coating.

Drying and curing are critical stages in the lifecycle of märkämaalit. Drying typically involves the evaporation of solvents or water, leaving behind the solid film. Curing, on the other hand, often involves a chemical reaction, such as polymerization or cross-linking, which further enhances the coating's durability, hardness, and resistance to chemicals and abrasion. The conditions under which drying and curing occur, such as temperature, humidity, and airflow, significantly impact the final quality of the finish.

Märkämaalit are essential for protecting substrates from corrosion, weathering, and wear, as well as for providing aesthetic appeal through color, gloss, and texture. The development of new märkämaalit continues to focus on improving environmental performance, such as reducing volatile organic compounds (VOCs), and enhancing functional properties like scratch resistance and self-cleaning capabilities.
