ALKYD MODIFIED CNSL RESIN (SILKYD 115)

Introduction

Silkyd 115 are CNSL modified with Long Oil Alkyd based Phenolic Resins. The Rosinated Alkyds are very popular in the Paint Industry. They were introduced primarily to reduce costs and to improve the drying time. But these advantages are gained at the cost of sharp deterioration of the properties of the original Alkyd particularly it’s chemical & water resistance & outdoor durability properties. Keeping these in consideration we have developed these resins. It reduces the drying time, improve the resistance to chemical & water & outdoor durability, yet the cost is lower than the Alkyds. They are Golden Reddish in colour and are suitable for Semi Dark colored & Dark colored Synthetic hard glossy enamels, insulating varnishes having outstanding film properties.

The CNSL Resins are reacted with Alkyds and have both ester & ether linkages in the structure. They exhibit outstanding water, alkali & chemical resistance combined with excellent weather resistance particularly because the modifying methylol is based on Phenol. The C-15 aliphatic chain further improves the flexibility and water resistance of the resultant polymer.

Solubility: Silex 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.

They are clear transparent and comparatively Golden reddish resins and are uniquely suitable for base formulations of synthetic enamels of superior quality with improved outdoor durability.

Applications: General Purpose Paints, Suger Glossy Enamels, Lacquers, printing inks, Compositions with high outdoor durability, Flexibility and gloss with better non yellowing properties but suitable for semi dark and darker shades.
