Abrasives Manufacturer Tips for Proper Abrasive Storage
1. Store all coated abrasives in areas that maintain a 40-50% relative humidity and at 60-80 degrees F. Humidity issues can cause cupping of coated abrasive products. In addition, if a sanding belt is in too high of humidity you can experience tracking or creasing issues and if stored in too low of humidity, the tape joint can dry out over time and break.
2. Abrasives should be kept in their original packaging for storage and cartons should be kept at least 4" away from damp or cold walls and floor where they might absorb moisture.
3. Abrasive storage should also be in a place that is out of direct sunlight, away from open windows and doors as well as radiators, steam pipes, furnaces and exhaust vents.
4. Precondition abrasive belts prior to use by removing from the carton and allowing to adjust to the ambient air. They should be rolled up and stored on their edge on a clean shelf or draped over a large cylinder, such as a gallon can or a flanged hanger of the type used for garden hose. NEVER hang a belt from a peg or nail--the back will crease and the abrasive may crack. This is especially important for wide belts, which should be removed up to 24 hours prior to use.
5. Rotate your stock--first in and first out!
Of course, always follow any abrasive manufacturers storage instructions included with the product. Questions? Feel free to visit us at www.abrasiveresource.com for more information...
