Excellent for stripping paint or sanding fairing compounds.
Purple abrasives are 3M’s best performing class of abrasives.
Both more durable and faster cutting than other papers, they provide the greatest dollar value and the highest quality in abrasive minerals available.
Faster cutting increases productivity, while long-lasting abrasive particles reduce sheet roll consumption — so shop techs spend less time changing sandpaper and more time sanding.
A blend of premium aluminum oxide mineral grains and the especially durable, synthetic ceramic mineral Cubitron™ for fast cutting and long sheet life.
