What are the main uses of alkyd resin?

Main uses of alkyd resin are in paints, coatings, and varnishes where hard durable glossy finish is needed. Alkyd resins are synthetic polyester resins modified with fatty acids from vegetable oils, and they are widely used as binder in oil-based paints and enamels. Main uses include architectural paints for trim, doors, cabinets, and furniture where hard enamel finish with good leveling is desired, industrial coatings for machinery and equipment, automotive refinish primers and topcoats, marine paints and varnishes for boats, metal protective coatings for rust prevention, wood varnishes and stains, and printing inks. Alkyd resins are also used in floor paints, corrosion resistant primers for steel, and as binder in artist oil paints. They provide excellent adhesion, gloss, hardness, and durability. Waterborne alkyds are used in low VOC paints. So main uses of alkyd resin are in oil-based enamel paints for trim and cabinets, industrial and marine coatings, wood varnishes, metal primers, and inks, where hard durable glossy protective finish is needed, making them versatile binder for both decorative and industrial coatings.
