BARTON garnet abrasives are naturally occurring minerals that do not contain chemical additives. There are no product expiration dates. However, proper storage methods need to be followed. Store abrasives in a cool dry place; preferably indoors. Keep container/package tightly closed and in a well-ventilated place without large temperature swings to prevent condensation. Abrasives stored in FIBC’s – flexible intermediate bulk containers, commonly called bulk bags, must be kept out of direct sunlight as UV light can deteriorate FIBC’s that are intended to be single use bags.
