alkydipohjaisiin

Alkyldipohjaisiin is a Finnish term that translates to "alkyd-based" in English. It refers to a class of synthetic resins widely used in the formulation of paints, varnishes, and coatings. Alkyd resins are polyesters modified with fatty acids and other components. The specific properties of an alkyd resin, such as its drying time, hardness, and flexibility, can be tailored by altering the types and ratios of the oils, polyols, and dibasic acids used in its synthesis.

These resins are valued for their good adhesion, durability, and gloss. Alkyd-based paints are known for their ease of application, good leveling properties, and ability to form a tough, protective film. They are commonly used in architectural coatings, industrial finishes, and automotive paints. The drying mechanism of alkyd resins is typically oxidative polymerization, where the unsaturated fatty acid chains react with atmospheric oxygen, leading to cross-linking and film formation. This process can be accelerated by the addition of metal catalysts, known as driers. Alkyd-based products are generally considered environmentally friendly due to their low volatile organic compound (VOC) content compared to some other solvent-borne coatings.
