TZJ- 2 calcined kaolin is a fine partical- size grade featuring high brightness. It has been dehydroxylated by controlled heat treatment for removal of crystalline- bound hydroxy groups and to improve brightness. TZJ- 1 calcined kaolin is highly pulverized of better dispersion.
TZI- 2calcined kaolin is widely used in flat architectural exteri/ interior paints as an opacifying extender. it hasa very good balance of optical and mechanical properties and also provides abrasion resistance in traffic paints. TZJ- 1 kaolin is a general- purpose grade used in a wide variety of polymeric systems. In these applications, it provides good resilience, low permanent- set and good electrical insulative properties. Typical applications: Water- bome
interior/ exterior flats, solvent- bome interior/ exterior flats, rubbers, TiO2 extension, polyamides, industrial safety coatings, film antiblock, electrical capacitors, rubber sealants/ adhesives, plastisols, mechanical rubber goods, electrical wire jacketing, TPE/ TPO, EPR power cables.
TZJ- 2 calcined kaolin used in papermaking usually has higher requirement in the particle size, brightness, oil absorbency and bulk density to improve the quanlity, such as the spreadability, glossiness, whiteness, smoothness and printability .
