PRODUCT: ALKYD MODIFIED CARDANOL RESIN (70%)
CODE: SILKYD 110 (70%)
INTRODUCTION: Silkyd 110are Cardphenol 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 its 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 resins and are uniquely suitable for base formulations of synthetic enamels of superior quality with improved outdoor durability.

Technical Write-Up of Silex-50 Plain CNSL Phenolic Resin
Introduction: Silex-50 is a Plain Cashew Nut Shell Liquid based Phenolic resins and is processed using special catalyst to cater to the need of various dark & semi dark coloured quick drying paints and primers. The resins has got both air drying and baking properties and is suitable for making high gloss dark & semi dark coloured paints, primers, anti-termite chemicals and varnishes, Black offset printing inks, Insulating Varnishes of outstanding properties particularly in regard to resistance to the water and chemical.
Compatibility: Silex-50 is compatible with all Drying oils, Alkyds, Epoxies, Ester gums, Phenolics, Maleics etc., in all proportion and only to a limited extent in chlorinated resins specially chlorinated rubber. It is not compatible with urea resins.
Solubility: Silex-50 is soluble in Mineral Turpentine oil (MTO) in all proportion. It is also soluble in most of the common paints solvent like Toluene, Xylene, Naphthas, Ester etc., but having limited solubility in Epoxies, vinyl & ethyl ketones.
Recommended Driers: Driers such as 0.5% lead or 0.5% cobalt and 1.5% Manganese as metal on the solid resin content is recommended. If require the proportion of Manganese can be increased to further 1.0% with beneficial effects. After addition of driers ageing for 24 hours is recommended.
Mode of Supply: It is supplied in 200 kgs packings as 100%, 80%, and 70% solids. For most of the paints and varnishes applications 70% execution is recommended as it has the best film properties & flowable from drums.
Application Technique:Film of Silex-50 can be applied either by brush, spray or flow technique.
Storage: The storage stability is Silex-50 is satisfactory for 6 months or more if stored in air tight containers in a cool place.
Recommended uses: Silex-50 either alone or in combination with other resins and used for formulating primers, dark coloured enamels and paints, insulating varnishes, knifing putty, Black offset Printing inks and similar other applications including special purpose anti corrosive paints baking composition etc.
Caution: Some times Silex-50 may be used along with basic pigment like Zinc Chrome,
Zinc Oxide, basic lead sulphate etc. It is advised that these pigments are not ground along
with the main pigment in the CNSL resin as there is a possibility of reaction. The reactive
pigments should be added after the grinding for proper dispersion of the Pigment. Hence it
is advisable to grind the main pigments with any Long Oil Alkyd Resin and then add our
CNSL resin outside and stir well to avoid reaction.
