What is the Shelf Life of…….???
This question is commonly asked among our distributors and customers. Product Shelf Life is the time frame in which our material/product maintains all of its optimum physical, chemical and electrical characteristics and properties.
The most critical parameter to consider is the temperature of storage. We strongly recommend that the material be stored at 70°F (+/-5) to maintain its optimum performance. Store in a dry place to avoid moisture and keep containers closed when not is use. Also, keep in mind the OSHA storage regulations for flammable liquids, CFR29- Code of Federal Regulations – Paragraph 1910.106-108.
Styrene and VT based polyesters are very sensitive to storage temperature.
Reactors for polybutadiene based products are especially sensitive to moisture as well as low temperature. If so, they need to be thawed out completely and mixed thoroughly before using in order to maintain their properties.
Generally, the shelf life period for Dolph products is 12 months from the date of shipment from our plant.
Exception: Aerosol spray cans have a shelf life of 18 months from the date of manufacture. This number is stamped on the top of the can under the cap. The number represents the day of the year. For example: 02199 is January 21, 1999.
Certain products do, however, have limited shelf life and are listed below. This is not a complete list. Therefore, for specific questions consult the product data sheet.
