Pearl luster pigments have the eluster as an additional property in comparison with otherpigments.Their characteristic properties of a faced structure,high refractory index and transparency create in a transparent medium and feeect equal to the luster of pearls.
Pearl luster pigments consist of a nucleus of mica,which is surrounded by several metaL oxide layers.Different gloss will be obtained by changing the oxides.
The excellent chemical,thermal and mechanical properties of the pigments provide universal application possbilities in paints,printing inks,plastics and many other uses.They provide the products with a new color quality.The pigments are physiologically harmless and can also be used in food packaging and toys for children.Diluted acids and alkalis do not damage them.The pigments are environmentally harmless as they are practically insoluble in water and do not contain any heavy metals.They are generally classified as not detrimental to water quality.The pigments are non-combustible and not self-igniting.They do not conduct electricity and can tolerate temperatures up to 800?.They can also be used as luster pigments for reactive paints such as radiation cured systems(electron beam curing ,UV curing).Their chemical structure allows for excellent dispersion making them appropriate for water based coatings |
