Product information
Chalk whiting is a versatile filler, useful for textured wall finishes as it provides high brightness and excellent whiteness. Among these, it is also profitable for rigid and flexible PVC, epoxy compounds, adhesives, rubber, printing inks, and paper products.
The fine soft nature of chalk coupled with a smooth, round particle shape and carefully controlled particle size distribution make it an ideal filler for various applications. Our unique deposit is free from the abrasive flints normally associated with chalk whiting.
