Long oil alkyd resins have an oil content greater than 55%. They are soluble in aliphatic solvents. Long oil alkyd resins are mostly used in varnishes, primers, architectural finishes, and industrial enamels.
Alkyd resin is a polyester with a monovalent fatty acid in its structure. Oil length is defined as the weight percentage of fatty acid contained in the total Alkyd Resin.
Based on oil chain length, ArChem Alkyd Resins can be classified into 3 categories as short oil alkyd resin, medium oil alkyd resin and long oil alkyd resin. Alkyd resins are used in various industries such as architectural paints and coatings, automotive paints, etc.
ArChem Alkyd resins are mostly employed as binders, adhesives, and plasticizers in surface coatings. They are made by combining polyols and anhydrides or acids with fatty or oily fatty acids in a condensation polymerization reaction.
In Long Oil Alkyd Resins, the amount of oil is more than 55% by weight and 20% to 30% of phthalic anhydride. They are dissolved in aliphatic solvents such as white spirit. Soy, linseed and sunflower oils are the most commonly used oil to make long oil alkyds. Glycerol and pentaerythritol are generally preferred as polyol sources.
Long oil resins are mostly used in architectural and maintenance areas, such as brush enamels, and marine paints. They generally have reasonable drying times and good yellowing resistance.
ArChem Long oil alkyd resin, due to its lack of brittleness and suitable adhesion, is a suitable choice for building paints and anti-rusts. In contrast with short oil alkyd resins, they have good solubility in aliphatic solvents. Some advantages of long oil alkyd resins include:
ArChem Long Oil Alkyd Resins contain a special amount of oil which assists smooth brushing and application to surfaces. They can be used for protection of wood surfaces and corrosion prevention of metal surfaces. Some application areas of ArChem Long Oil Alkyd Resins are:
