Product Description

We are able to hold a commendable market presence in both domestic and international area by manufacturing and exporting an exceptional range of Ceramic Microspheres. Offered in two colors viz. gray and off-white, these microspheres are appreciated for their properties like low density, high melting point and electrical & heat resistance. Our Ceramic Microspheres are used for increasing hardness, providing gloss, increasing filler loadings and improving hardness and burnish of a variety of coating formulations. Moreover, our clients can avail these microspheres at pocket friendly prices.


Why Our Ceramic Microspheres?
