CRISTAL 121

CRISTAL 121

 Cristal 121 is an alumina/silica modified rutile pigment produced by the chloride process. Designed for use as a multipurpose grade it offers a blend of good optical performance with a high level of durability for an optimum balance required by pigments used in exterior applications. As well as being suitable for exterior applications, its suitability for interior use can offer advantages to formulators in minimizing inventory.

  Cristal 121 is recommended for many classes of coatings including architectural, industrial and maintenance coatings. It is suitable for use in solvent or water based applications for either interior or exterior use. It can also be used in plastics where durability is of consideration, and can also be used in powder coatings.
