Short Oil Alkyd Resin

Definition - What does Short Oil Alkyd Resin mean?

A short oil alkyd resin is an alkyd binder made with a short oil to alkyd resin ratio. These resins contain less than 40 percent fatty acids (modifying agent).

The short oil alkyd resins are generally oven dried as they cannot be air dried. Typical solvent systems for these products are the alipahtic solvents. Some may be cut in aromatics or oxygenated solvents for high solids. Most will accept infinite dilution with aliphatic solvents.

Corrosionpedia explains Short Oil Alkyd Resin

Alkyd resin products are suitable for a wide range of paint products with applications in decorative, maintenance and contractor paints where excellent gloss and good durability are required.

Short oil alkyds are typically oven dried with the solubility limited to aromatic and other non-aliphatic solvents. Coating systems manufactured using these resins are used in air drying primers for wood or metal, machinery enamels, industrial paints, traffic paints, floor enamels and low bake finishes.

Besides short oil alkyd resins, there are two more types of alkyd resins: long oil alkyd resins and medium oil alkyd resins.

  • Long oil alkyd resin contains more than 60 percent fatty acids by weight.
  • Medium oil alkyd resin contains 40% to 60% fatty acids by weight.
  • Short oil alkyd resin contains less than 40% fatty acids by weight.
