light calcium carbonate for paintings

1.purity:99.2, whiteness 95 2.size(mesh):800~1000 3.ISO9001 4.Oil absorption:38, sedimentation:2.6, moisture:0.3

light calcium carbonatemainly used as the materials to enhance the rigidity and intensity of products. Increase electric indulation and heat resistance, dectease shrinkage and improve ohysical dynamics performance.

applications for paints:  

our features

Hight whiteness ,powder,low impurity, adopting dry surface treatment technique,with high activation rate.
