Proper storage is
essential with coated abrasive products, ideal conditions being:
Temperature range 60
degrees to 80 degrees F.
Humidity range 35% to
50% R.H.
Correct storage is vital when the finished product
has a large surface area such as a wide belt. The simplest storage
unit would be a room (enclosed) with 40 – 60 Watt light globe at
ground level to maintain relatively dry conditions. Coated abrasives
should never be stored where extreme variations in temperature and
relative humidity occur, such cyclic changes can bring about rapid
deterioration of the bond and the backing. Provided coated abrasives
are not subject to extreme variations of temperature and R.H.,
performance should not vary greatly.
