INTRODUCTION: Silkyd 110 are Cardphenol modified with Long Oil Alkyd based Phenolic Resins. The Phenolic Alkyd modified resins are very popular in Indian 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 yellow in colour and are suitable for Semi Dark colored & Semi Light colored Synthetic hard glossy Enamels, Furniture Enamels, Insulating Varnishes having outstanding film properties.
The Cardphenol 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.
They are clear transparent and comparatively Pale Yellow resins and are uniquely suitable for base formulations of Synthetic Enamels of superior quality with improved outdoor durability.
