We define shelf life as “the period of time a product remains suitable-for-use when stored within the recommended storage conditions.” When used during this period, the product is expected to achieve the intended performance properties when fully cured under proper conditions.
Product expiration dates are calculated as beginning from the date of manufacture.
All Astro product labels indicate the product’s manufacture date, expiration date, and usable shelf-life. Expiration dates provided on our labels are always based on optimal storage conditions that allow the maximum shelf life possible. Always refer to the Astro product label for specific details regarding any purchased materials.
