Wood Sanding, Aluminium Oxide will have a softer cut and will leave the smoothest finish of any traditional abrasives. These are our "STEARATE" sheets. They are Aluminum Oxide, resin bonded, paper backed for long life and tear-resistance. This material is recommended for bare wood sanding and autobody use. Applications include sanding of bare metal, primer surfacer and between coats of paint, lacquer, and shellac. Also useful on sanding of solid surface countertops such as CORIAN, FOUNTAINHEAD, and AVONITE. Our very high-quality Zinc Stearate material, added in the size coat, will outperform virtually all competitors. Pro Wood Construction Manufacturing division is utilizing that sandpaper from the beginning and is very satisfied with the quality and durability.
