INTRODUCTION: SILEX ^TM 85 is Card Phenol based Phenolic Resins modified with Rosin. They are Golden Reddish yellow resins and are suitable for manufacturing Synthetic Hard Gloss Semi Darker & Darker Enamel Paints, Insulating Varnishes and Aluminum Medium 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 ^TM 85 are soluble in most of the Aromatic & Aliphatic hydrocarbon solvents like Mineral Turpentine Oil (MTO), Xylene, Toluene, Solvent Naphtha etc., They are supplied in 80%, 70% & 50% solid contents.

Film Characteristics: The film characteristics have been studied making the resin to 40% solids in Mineral Turpentine, Driers added are 1% Lead, 0.5% Cobalt & 1.0% Manganese as metals in their Octoate and the varnish is left for 24 hours for ageing, properties as per IS specifications 197-1972. These resins have very good film forming property, gloss, hardness and water resistance. These properties are beneficial to paint manufacturers as SILEX ^TM 85 resin is economical. However SILEX ^TM resins can be incorporated in regular paint formulation to reduce cost and adjust quality.

Applications: Red oxide metal primer made with SILEX ^TM 85 does outstanding performance and corrosion protection. In interior enamels SILEX ^TM 85 resin is added to reduce cost of formulation and also improve gloss. Generally the pigments are ground in long oil alkyd and SILEX ^TM 85 resin is added in dilution and thinning. Incorporating Long oil alkyd in SILEX ^TM 85 formulation improves flexibility and durability. SILEX ^TM 85 has better properties so it is recommended for use in interior enamels. SILEX ^TM 85 based formulations tend to yellow when exposed to sunlight and the shade of the paint darkens. SILEX ^TM 85 based formulations are not suggested for exterior finishes.

Storage: The storage stability of SILEX ^TM 85 Resins are infinite if stored in tight containers in a cool place.
