Storage and Handling

Pro Catalyst Powder and Pro Catalyst Liquid should be stored in its box at all times until just prior to use. Always store in a cool and dry location. Do not store in direct sunlight or in temperatures below 32°F (0°C) or above 77°F (25°C). 

Materials stored on the project site during application should be kept on a pallet in a shaded, well-ventilated area. In unshaded areas, materials should be covered with a white, reflective tarp in a manner that allows for air circulation beneath the tarp. 

Pro Catalyst Powder and Pro Catalyst Liquid are stable if stored and used in accordance with Siplast guidelines. Pro Catalyst Powder and Pro Catalyst Liquid are heat sensitive and should be stored under controlled conditions to ensure that the reactivity/effectiveness is not compromised as well as for safety reasons. Pro Catalyst Powder and Pro Catalyst Liquid should not be exposed to temperatures in excess of 122°F (50°C). Products exposed to temperatures in excess of 122°F (50°C) may experience hazardous self-accelerating decomposition. Self-accelerated decomposition is signaled by the presence of bright white smoke and the process can generate high temperatures, depending on the environmental conditions and quantity of product. 

The shelf life is 6 months from the ship date. A use-by date is listed on each box. Shelf life is reduced if product is stored at temperatures exceeding 77°F (25°C). Pro Catalyst Powder and Pro Catalyst Liquid should not be used if the shelf life is expired. 

See product packaging and the Safety Data Sheet for specific information on the safe handling of this product.
