Abralon® J3 is a unique, multifunctional Abralon abrasive for an ultrafine finish for both smooth and profiled surfaces. Abralon J3 has a higher density foam layer which is only 3 mm thick. Recommended for high gloss applications, it leaves a very smooth surface prior to polish. Abralon J3 is suitable for all kinds of material. The flexible weave allows water and air to pass freely to make it suitable for both dry and wet sanding.
