How are Coated Abrasives best stored?
The backings and adhesives used in coating abrasives are very sensitive to climatic variations in temperature and humidity; resin bonded grinding wheels suffer the same fate. It is therefore most important to store coated abrasive and resinoid products in an environment which reduces their degradation by atmospheric conditions. The ideal environment is a temperature between 16 and 24ºC (60 to 75ºF) and relative humidity between 35 and 50 percent. Abrasive belts, in particular, should be hung in an attitude similar to the curvature of the wheels on which they will be used, in order to prevent undulations in the belt, which may upset the machined surface finish.
