Castung™ Dehydrated Castor Oil Series

Dehydrated Castor Oil (DCO) is well known for its non-yellowing and outstanding color retention characteristics.  Varnishes, alkyds and resin systems based on DCO are noted for fast-dry, flexibility, excellent chemical resistance, adhesion to metals, high gloss and water-resistance.  The Castung Dehydrated Castor Oils are the most controllable conjugated oils for kettle reactions and are frequently used to modify other oils and fatty acid systems.

Applications

In “cooked” varnishes, Castung Dehydrated Castor Oil combines with all the basic resins, rosins, rosin-esters, hydrocarbons and phenolics producing clear varnishes and vehicles for pigmented coatings. 

Castung Dehydrated Castor Oil can be added to architectural latex paints, improving the wet adhesion to previously painted substrates. 

Castung Dehydrated Castor Oils are primary raw materials for the production of fast curing short oil alkyd industrial coatings.

Values shown in the above table are typical properties.

Castung™ 103 G-H Oil is an unbodied dehydrated castor oil that is light colored and low viscosity.  It is a triglyceride very high in linoleic acid content and no linolenic acid content resulting in light color and a non-yellowing property in its dry film.  It can be used with pure and modified phenolic resins to obtain fast-dry coatings, alkali resistance for can linings, corrosion resistant coatings, traffic paints, ink vehicles and marine finishes.  Castung 103 G-H Oil is an excellent plasticizer for petroleum hydrocarbon resins and is preferred for alkyd and copolymer resins.

Castung™ 403 U-V Oil is a bodied dehydrated castor oil polymerized to a medium viscosity. It has faster processing and drying times than Castung 103 G-H Oil. This product also has the same non-yellowing and outstanding color retention characteristics. It is a modifier resin that imparts increased brushability and gloss in exterior coatings.

Castung™ 403 Z-3 Oil is a bodied dehydrated castor oil polymerized to a higher viscosity. It has faster processing and drying times than Castung 103 G-H Oil. This product also has the same non-yellowing and outstanding color retention characteristics. Castung 403 Z-3 Oil is ideal as an aluminum paint vehicle because of its fast drying, flexibility, and low acid value.
