Chalk whiting is a versatile filler useful to textured wall finishes as it provides high brightness and excellent whiteness. Among this it is also profitable to 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 a variety of applications. Our unique deposit is free from the abrasive flints normally associated with chalk whiting.
