SAFETY AND HANDLING
ETHANOX 4733 fuel antioxidant additive tends to supercool and can therefore rapidly crystallize when stored
below its freeze point. ETHANOX 4776 fuel antioxidant additive minimizes this problem. If crystals form, lowpressure steam or drum warmers may be employed.
Before handling or using this product, please refer to the material safety data sheet (MSDS). Copies are available
