alkyd

The term "alkyd" refers to a type of synthetic resin used primarily in paints and coatings. Alkyds are made by chemically modifying natural oils (such as soybean or linseed oil) with polyols and dibasic acids or anhydrides. They are commonly used in oil-based paints and enamels due to their durability, gloss retention, and good adhesion properties.

In the painting and decorating industry, alkyd paints are known for:

• Hard-wearing finish – ideal for high-traffic areas or surfaces that require frequent cleaning.
• Smooth application – they level well and provide a professional-looking finish.
• Longer drying time – compared to water-based paints, which allows for better flow and leveling but requires more time between coats.

In Australia, alkyd-based products are often used for trim work, doors, metal surfaces, and cabinetry, especially where a tough, glossy finish is desired. However, due to environmental regulations and the push for low-VOC (volatile organic compound) products, water-based alternatives are increasingly popular.
