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, Naphtha’s, Ester etc., but having limited solubility in Epoxies, vinyl & ethyl ketones.
Recommended Driers: Driers such as 1% 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 kg’s packing’s 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.
Applications : Air drying cum Baking Enamels, Semi Dark & Darker Enamels, Insulating Varnishes, Food Can Lacquers, Wood Polishes, Metal Primers, Coatings for Anti-Corrosive Properties etc.
