Bayer Grade ATH

With an average particle size of 22 microns, Bayer Grade ATH has excellent air release properties. With an off-white color, it is less expensive than white grades and has short lead times.

Applications for Bayer grade ATH are for customers who develop their own sold surface granite colors and need a proven base filler material.

OC 1500 is a white grade of ATH with excellent air release properties at a competitive price. With no yellow or brown cast to its color, OC 1500 is a market proven product and ideal for solid surface applications.
The NEW AC-25MSP offers many of the same features as the OC-1500 yet with an improved consistency.
