Short Oil Alkyd Resin

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. The percentage of fatty acids in the short oil alkyd resins is less than 40 percent. These fatty acids act as the modifying agents in the resins.

The short oil alkyd resins are generally oven dried because 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 paints or any other product that contains alkyd resin finds application on a wide range of paint products where they can be used as a decorative material paint, or as maintenance or contractor paints. These paints or coatings provide excellent gloss and durability to the substrate material.

In the case of short oil alkyds, these resins are generally oven dried and have a limited solubility only with aromatic and other non-aliphatic solvents. Coating systems manufactured using these resins are used in air drying primers for wood or metal, floor enamels, machinery enamels, traffic paints, industrial paints 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% 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.
