Castor Oil for Ink, Paint, Varnish and Rubber
Derivatives produced out of castor oil has myriad uses. They are versatile raw material and are highly in demand.
Dehydrated Castor Oil (DCO)
DCO is used as primary binder for paints, enamels, sealants, inks and more. It has functional use for production of alkyd resins, acrylic and epoxy ester resins for paint industry, coatings and as an additive in ink formulations.
Dehydrated castor oil is a drying oil that has low residual odour. It imparts fine gloss, toughness, adhesion, flexibility and gives chemical and water resistance. Paints which integrate this oil grade are super white and delivers superior finish. DCO is used with phenolics to obtain fast dry coatings with maximum alkali resistance as required in sanitary can linings, corrosion, resistant coatings, high-performance traffic paints, varnishes, vehicles, wire enamels, aluminium paints, appliance finishes and marine finishes etc. The polymerized version of Dehydrated castor oil upto 220 poise can be used in paints and varnish industry. To give good finesse it is utilized is lenoleum putty and phenolic resin. Polymerized DCO is used with petroleum resin based cold cuts.
Blown Castor Oil
Blown castor oil is also known as oxidized oil. Blown castor oil is a derivative with higher viscosity. It is prepared by blowing air or oxygen into castor oil. This is called oxidative polymerization. Oxidative polymerization of castor oil yields products with increased viscosities resulting from oxidative polymerization, increased compatibility with various resins and improves ability to wet and disperse pigments while imparting solvent and abrasion resistance to lacquer systems – Lacquer systems are highly resistant to weather conditions and unaffected by industrial emissions. Castor oil which is polymerized are used to plasticize a variety of resins in adhesive, heat-set inks and sealant systems. Blown castor oil is also used in hydraulic fluids and as lubricity additive in manufacturing of lithographic inks. Blown castor oil has been classic plasticizer of shellac rosin, natural and synthetic resins, the celluloses and for natural and synthetic rubbers.
Refined Castor Oil
During the refining process of castor oil, impurities such as phospholipids, colloidal matter, FFAs and colouring agents are removed so that it doesn’t deteriorate and its storage life is extended. The refining process steps include neutralization, bleaching, degumming and deodorization. Refined castor oil is used as substantially insoluble and infusible polymer. As a lubricant it is used in petroleum emulsification- hydraulic and brake fluid, polish, inks, paints, rubbers etc. It is used in combination with styrene and diisocyanates for film forming.
