HA-90
(Calcined Kaolin in Papermaking)


.Benefits and Application
HA series, a calcined kaolin pigment, has advantages of high brightness, excellent light scattering, fine particle and low abrasion value. It can be used in filling and coating, especially in coating. Its main benefits are:
It can cut costs by replacing titaium dioxide or other expensive filling pigment.
It can improve paper's properties, such as smoothness, glossiness and opacity.
It can improve ink absorbency and print adaptation.
It has excellent compatibility with various additives.
Compared with other pigments, low viscosity of dispersed phase while the consistency is high, So It can be commpouded in high solid contedt coating and be applicable to high speed coatings.
