The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in abrasives are very sensitive to changes in temperature and humidity. Abrasives are best stored at temperature levels of 60 to 80 degrees Farenheit and a 35 to 50 percent relative humidity. Products should be kept in their cartons until you are ready to use them. Cartons should be clear of any heat sources, cold walls, and off of damp floors.
Why is corundum or silicon carbide used?
Corundum is the most frequently used abrasive. The purer the corundum, the harder it also is, which can be determined from the colour. The toughness can be increased by adding various metal oxides and by shortening the cooling
