Compatibility with Drying Oils: Silex 75 is compatible in all proportions with drying oils (Linseed Oils, DCO etc). Their compatibility with other resins like alkyds epoxies is also very good.
Solubility: Silex 75 is soluble in most of the aromatic and aliphatic hydrocarbons. Eg. Mineral Turpentine Oil (MTO), Xylene, Solvent Naphtha etc.
Recommended Driers: Drier combination such as 1% Lead or 0.4% Zirconium, 0.1% Cobalt and 0.1% Manganese as metals on the solid content of the resin, with ageing of atleast 24 hours is recommended. The films of Silex 75 dry hard in air, under ambient conditions in about 2 to 3 hours when recommended driers are added. The dried film is clear, glossy to Dark Reddish Brown colour with excellent properties like adhesion, hardness, flexibility and good resistance to water and chemicals. The film dries hard within 15 to 20 minutes when baked at a temperature of 120°C.
Mode of Supply: The above resin is supplied in 200 and 25 kgs packing in 100%, 80% and 70% solids in MTO. For most of the common paint and varnish applications the 80% or 70% executions are recommended as they have better film properties.
Silex 75 along with suitable driers can be used as good film former. However, if still better film properties like flexibility are desired, they are to be modified with suitable drying oils or other resins like alkyds, epoxies etc.
Highly recommended for interior paints, enamels and Wood varnishes. Also recommended for Black Offset Printing Inks, Insulating varnish & Wood Varnishes. Silex 75 has extra gloss compared to Silex 50. They are Transparent Golden Reddish in colour.
Applications : General Purpose paints and enamels, Redoxide, Primers, Insulting varnishes and printing Inks
