Due to the wet grinding process, our mica displays exceptionally good shine and luster giving a natural pearl effect. It also has unique UV Resistant properties. It's an exceptionally stable, chemically inert mineral that is harmless to humans making it suitable for the following applications:
• Pressed powders
• Body powders
• Liquid Makeup
• Lipstick
• Nail Lacquers
• Sun Screen - Creams
The Quality is an agreement between the customer and Micatech relating to the specifications, test methods and standard samples. Micatech is committed to give their customers, consistent quality assurance for their entire range of products. The objective of the quality is to reduce or eliminate the testing at the customer's end, by properly understanding the customer's requirements.
Micatech has elaborate testing facilities for carrying out testing of Raw material as well as Finished products. Raw material testing includes its physical properties and suitability of raw material by actual method. This insures consistent quality of the product. The Finished product's testing is carried out in its final application, which helps customers to reduce testing time and costs involved. Stringent specifications and procedures for the purchase of raw materials, processing parameters and specifications of the finished goods testing are being laid down in detail by the Quality Control Department and being strictly followed, without any compromise and deviations from the standards.
Micatech laboratory is well equipped with the most advanced quality control instruments to produce highest standards quality and consistency. The technique used for measurement of various important properties involves a series of procedures. The systems are divided into main areas-daily production dispatch sample analysis, inspection of stock and data monitoring. Micatech R & D and Quality control Laboratory have some of the best trained and experienced Scientist, Chemists, and Engineers to study the needs of customers, undertake continuous product up gradation, improvement and maintain consistency in quality.
Customer criticisms are seen as an opportunity to make improvements- this is the attitude of employees at all levels. Each criticism helps Micatech improve its system and products.
