Dear Sir, We are best quality Talc Exporters. Are you Paint, Coating, Paper, COSMETICS, PHARMACEUTICALS, PLASTICS etc. Manufactures? Are you interested regarding Talc? Please contract us. TALC FOR PAINTS & COATINGS USE. Dry Hiding and TiO2 extender: Talc with high lamellarity occupies more surface area traps more air into the film as it dries giving a dry hiding effect above the CPVC. TiO2 pigment efficiency can be enhanced through better spacing in the highly lamellar talc. Highly lamellar, fine ground with high brightness talc are recommended for this function. Anti – Corrosive: The platelets in the talc protect the substrate by impeding water diffusion through the film. The hydrophobic nature if the talc platelets produce such barrier effects. Anti – Cracking: Talc and other related minerals are used to give a significant reduction in cracking which results because of the interaction of different binders and other paint components. The Talc lamella offers strong resistance to the tensions that builds up the drying film. Matting: Our high purity Asbestos free, platy Omtalc is used in the decorative matt paints to obtain a deep matt finish. Finer Omtalc can be used in varnishes and low PVC paints to obtain semi glass. Rheology: A remarkable rheological effect is produced during interaction of talc particles and paints resins and other components which inturn increase the low shear viscosity and prevents sagging. The evenly distributed platelets also reduce settling. Owing to its low cost and platy structure, Talc is widely used in the paint industry, particularly in marine paints and protective coatings. Benefits include: Reinforcement of the Paint film. Reduction in the quantity of primary pigment consumed. Controls gloss of paints helps in suspending other pigments. Improves durability of Paint. Improves rust inhibitive properties & corrosion resistance. Improves stability of emulsion paints. Prevents enamel from running. In traffic paints for better abrasion resistance. Improves stain resistance in Paint. Enhancement of smoothness at the time of application. The amount of Talc used in paints varies between 2 to 30%. Also the fineness of Talc used in paints varies between 100  to 20. The oil absorption of Talc used in Paints is between 40 to 60 gm per 100 gm. TALC FOR PAPER USE. The Paper industry is the largest consumer of Talc and generally uses 300 Mesh (53 ) with the range of brightness varying between 80% to 96%. Talc is used in three stages of Paper making:  As a filler to give smoothness, porosity and opacity to paper in addition to reducing the cost.  To control Pitch & Stikies ….. during the paper making process, oleoresinous droplets micro or colloidal in nature get added to the stream. These micro impurities can clog the paper machinery. Talc being hydrophobic absorbs these micro droplets or if the droplets are big then talc lamellae stick to their surface thus controlling their stickness.  In coating formulations….because of its platyness and high brightness, talc leads to reduction in usage of expensive whitening and helps in controlling gloss of the coat. Talc also provides smoothness to the surface and imparts opacity to the coat. Additionally talc reduces the friction on paper manufacturing machinery thus reducing wear. TALC FOR COSMETICS USE. The natural qualities of Talc gives cosmetics stability, texture, skin adhesion, slip and water resistance. Talc is pure, odourless and free from impurities. Talc is not only used in Body Talc and Toilet Soaps, but also in detergents and Washing powder. In body Talc, it acts as a perfume carrier due to its chemical inertness and lamellar structure. At Golcha’s, supplies to body talc manufacturers are also sterilized remove any microbiological contamination. In soaps, talc is mainly used as a filler. The consumption of talc in soap, varies between 5 to 40% depending on the quality and type of soap. It also acts as a binding agent and gives hardness to the cake. TALC FOR PHARMACEUTICALS USE. Although a small user, the pharmaceutical industry requires highly pure, specialized and bacteria free talc for Tablets, Ointments and Dusting. The thermal & chemical inertness of talc makes it an ideal filler. TALC FOR PLASTICS USE. With the plastic industry on a fast growth-track, the usage of talc is growing fast in PP, HDPE, LDPE, PVC, ABS & Thermosetting compounds. Talc is having a huge demand as a filler due to its following properties:  Platy in Nature.  Excellent blending characteristics with oleoresinous materials.  Excellent thermal resistance.  Superior electrical resistance.  Chemically inert.  Smooth greasy feel. In polypropylene, talc is used to improve mechanical strength and scratch resistance. The Automotive Industry uses talc for dashboards, interior trims, bumpers etc. Talc is also used in plastics for computer bodies and garden furniture where increased UV resistance is a highly desirable characteristic. It is also used as anti blocking agent in film like bags used for fruits, vegetable etc. Many compounding factories are also using Talc. Talc imparts the following properties to plastic:  Improves Chemical & Heat resistance.  Improves impact absorbing strength.  Gives dimensional stability.  Improves stiffness, hardness, tensile strength.  Gives electrical insulation property. The plastic industry uses Talc of 20 to 1 particle size. TALC FOR CERAMICS USE. A major consumer of Industrial minerals, the Ceramic industry (especially Asia) uses Talc for “body” and glazing of: Wall tiles, Sanitary Ware, Electrical Insulating (Stealtite Talc) Porcelain Dinner Ware. The talc used is generally of 80 ~ 93% whiteness and 200 – 300 mesh. TALC FOR PHARMACEUTICALS USE. USP Certification limit: Loss on Ignition 6.5% Maximum Acid Soluble 2% Maximum Water Soluble 0.1% Maximum Water Soluble Iron Nil Microbiological limit 500 per gram Micro Talc USP and BC Talcs are designed for Medical, drug & cosmetic formulation both powder and lotion. Talc’s softness, oleophilic surface and fragrance retention characteristics make them ideal material for these applications. Talc Ompharm USP talc is used primarily as ingredients in drug & OTC tableting formulations where it acts as a binder and mold release agent. Ompharm 60-30 USP. Thanks. Best Regards, Fasahat Hussain.
