OptiSpray® Roving should be stored in its original packaging in a dry and cool place. Best conditions are at temperatures from 10° to 35°C (50 to 95°F) and humidity between 35%-85%. If you store the product at lower temperatures, please move the soon-to-be-processed pallets to the production area 24 hours ahead of time. You can stack pallets one-on-one with a plywood plank between the two.
