Alkyd Resins-Long Oil

An alkyd is a polyester resin modified by the addition of fatty acids and other components. Alkyds are derived from polyols and organic acids including dicarboxylic acids or carboxylic acid anhydride and triglyceride oils.

The term alkyd is a modification of the original name “alcid”, reflecting the fact that they are derived from alcohol and organic acids.

Long oil alkyd resins are those that have an oil content greater than (55%)60%, something that helps give a smooth brushing action. Long oil alkyd resins are soluble in aliphatic type solvents (white spirit) and are mainly used in:

Interior & exterior house paints
High gloss paints
Varnish & floor sealers
Anticorrosive paints etc.

A long oil alkyd can be applied to wood surfaces for protection and to metal surfaces for corrosion prevention. It does this by acting as a film forming agent due to its polyester component.

PRINCIPAL PROPERTIES :

High Gloss
Very good colour retention
Excellent finish
Solubility in MTO.
