PHENOLIC RESIN SILEX 70 PLAIN CARDPHENOL RESIN
TECHNICAL WRITE UP
INTRODUCTION: Cashew nut shell liquid contains Phenolic group called Anacardic Acid. CNSL oil is distilled and Card phenol is separated. Card phenol is polymerized and modified with Alkyds, Styrene monomer and Rosin to make different grades of modified Card phenol resin. SILEX-70 is Plain Card Phenol based Phenolic Resins. They are Golden Reddish yellow resins and are suitable for manufacturing Synthetic Hard Gloss Semi Darker & Darker Enamel Paints, Insulating Varnishes, Aluminum Medium etc., & are having outstanding Film Properties. They can be blended with any conventional alkyds and can be used for making Lighter colour shades also.
COMPATIBILITY: These resins are compatible with all drying oils in all proportions like Linseed Oil, DCO, Soya etc., Their compatibility with other resins like Alkyds, Epoxies is also very good.
SOLUBILITY: SILEX-70 are soluble in most of the Aromatic & Aliphatic hydrocarbon solvents like Mineral Turpentine Oil (MTO), Mineral Spirits (MS), Xylene, Toluene, Solvent Naphtha etc.,
RECOMMENDED DRIERS: Driers added are 1% Lead, 0.1% Cobalt & 0.1% Manganese as metals in their Octoate and the varnish is left for 24 hours for ageing. These resins have very good film forming property like high gloss, better hardness and water/chemical resistance. These properties are beneficial to paint manufacturers as Cardphenol resin is economical compared to conventional Alkyds. However pure Cardphenol resin can be incorporated in regular paint formulation to reduce cost and adjust quality.
MODE OF SUPPLY: It is supplied in 200 or 25 kg’s packing’s as 100%, 80%, and 70% solids in MTO. For most of the paints and varnishes applications 70% execution is recommended as it has the best film properties
