Talc powder (CAS 14807-96-6) is a natural hydrous magnesium silicate mineral (Mg3Si4O10(OH)2) supplied in micronized powder form (300 to 1250 mesh cuts) in 25 kg and 50 kg bags by KIKI'S Industrial Chemicals in Nairobi. It functions as a platy barrier pigment in paints and coatings, a reinforcing filler in polypropylene plastics, and an anti-tack processing aid in rubber compounding across Kenya and East Africa.
Talc powder is an industrial lamellar mineral filler featuring high softness (Mohs 1), chemical inertness, high whiteness, and hydrophobic surface properties.

Industrial Micronized Talc Powder (CAS 14807-96-6) in 300 to 1250 mesh cuts supplied in 25kg and 50kg bags by KIKI'S Industrial Chemicals for paints, plastic compounding, rubber, and ceramics across Kenya and East Africa.
Available Packaging
Talc is a naturally occurring hydrous magnesium silicate mineral (Mg3Si4O10(OH)2) celebrated as the softest known mineral (Mohs hardness 1.0). Structurally, talc consists of a sheet of brucite-like octahedrally coordinated magnesium sandwiched between two sheets of silica tetrahedra, bonded together only by weak van der Waals forces.
This sheet-like (lamellar or platy) crystal structure imparts extraordinary natural properties: chemical inertness, high thermal stability, hydrophobic water repellency, low electrical conductivity, and high lubricating lubricity with anti-stick performance.
KIKI'S Industrial Chemicals supplies verified industrial-grade talc powder imported from certified mineral processors in India in both 50 kg PP bags and 25 kg paper bags. We serve paint manufacturers across Nairobi and Athi River, plastic compounding plants, and rubber extrusion factories across East Africa.
In architectural paints, anti-corrosive primers, and marine coatings, talc's flat, plate-like particles align parallel to the substrate surface as the film cures. This creates a tortuous 'shingle effect' barrier that dramatically impedes the penetration of moisture, oxygen, and corrosive ions through the paint film to the underlying steel.
Furthermore, talc's lamellar shape improves film flexibility, prevents mud-cracking in thick-coat primers, controls sheen, and acts as an anti-settling agent by suspending heavier primary pigments such as titanium dioxide during shelf storage.
In polypropylene (PP) and automotive engineering plastics, micronized talc (800 to 1250 mesh) acts as an active functional reinforcing filler rather than a mere diluent:
Because natural talc deposits can geologically co-occur with asbestiform amphiboles, KIKI'S enforces strict mineralogical screening. Every commercial batch is backed by laboratory verification (X-Ray Diffraction and Polarized Light Microscopy) certifying the total absence of asbestiform minerals (< 0.1% limit) and controlled respirable crystalline silica levels.
Specify your required fineness mesh grade (e.g. 300 mesh for architectural paint primers, 800 mesh for industrial enamels, or 1250 mesh micronized for polypropylene compounding), target whiteness, and delivery location.
Commercial Sectors
Kenya's paints, decorative coatings, and wood finish manufacturing industry requires pure virgin solvents, high-brightness extender pigments, and specialized coalescing aids. A formulation is only as good as its raw materials: low-purity thinners cause pinholing and blushing, while coarse fillers destroy gloss and opacity. KIKI'S supplies premium solvents, extenders, and binders to East Africa's leading paint makers.
Kenya's plastics and PVC conversion sector—producing water pipes, electrical conduits, packaging films, and molded components—depends on precise compounding chemistry. Processing heat degradation, poor filler dispersion, and polymer brittleness can halt high-speed extrusion lines. KIKI'S supplies premium calcium carbonate extenders, plasticizers, lubricants, and PVC solvent cement reagents to leading converters.
In manufacturing clusters across Nairobi, Athi River, and Baba Dogo, continuous production depends on reliable supply of process chemicals, boiler water conditioners, and high-flashpoint cleaning solvents. A production stoppage caused by boiler scale or a missing raw material costs millions of shillings per hour. KIKI'S provides the reliable chemical supply that keeps Kenyan manufacturing plants operating at peak output.
Automotive assembly, commercial fleet workshops, and radiator shops require uncompromising chemical performance—from battery electrolytes and monoethylene glycol coolants to heavy solvent degreasers that slice through road tar and diesel grime. KIKI'S supplies technical chemicals that keep East Africa's vehicles moving.
Process Compatibility
Store talc bags on dry pallets in an enclosed, weather-proof warehouse away from moisture and direct rain. Although talc is naturally hydrophobic, paper and woven packaging can absorb humidity, causing powder compaction.
Stack bags no more than two pallets high to prevent compaction and bag rupture. Practice clean warehouse housekeeping with HEPA vacuum collection to prevent dust buildup on floors.
Operators dumping bulk talc bags into high-speed dispersers or compounding hoppers must wear fitted particulate respirators (N95 or FFP2). Use localized extraction hoods over mixer charge ports to capture fugitive airborne dust at the source.
Avoid sweeping dry spilled powder with brooms, which aerates fine mineral particulates into the breathing zone. Use wet wiping or vacuum collection.
Inhalation: Move person to fresh air. If coughing or breathing difficulty persists, seek medical evaluation. Eye Contact: Flush eyes with copious water for 15 minutes; do not rub eyes (abrasive particles). Skin Contact: Wash off with soap and water.
