What is the best way to store my powder? How long can powder be stored?
Powder storage for many months is often normal practice. Ideally, powder should be stored in the optimum conditions of less than 80°F and approximately 50 – 60% relative humidity. Under these conditions most powder should be readily usable for at least a year. Avoid placing powder inventory in close proximity to any heat source such as an oven, washer, furnace, space heater, etc. Powder packaging is designed to protect the contents from compression that can result in lumps that are not readily broken. Do not stack packages that are broken or collapsed. Some powders with special appearance, performance, or cure properties may have greater sensitivity to storage conditions, and should receive greater attention when stored to ensure the desired results.
