Storage and Shelf Life

Performance of our epoxy products is guaranteed for three years from the date of manufacture, printed on the bottom of the containers, provided they are stored properly. They will probably last much longer, but they should be tested first after the three-year period. The resin may crystallize or the hardener may darken but this does not affect its performance. Crystallized resins should be reheated in a water bath that is at least 125°F until the resin clears up prior to use on the project.

Crystallization occurs when the product is exposed to low temperatures for prolonged periods of time; the presence of any impurities will then initiate the crystallization process. 
System Three products are formulated to resist Crystallization, but it can still occur. 
Heat will bring the resin back to a usable state, and the best way to heat the resin is to place the container in a water bath with water heated to 125°F. 

System Three Silvertip Yacht Primer and WR-LPU Topcoat paints are guaranteed for 3 years from the date of manufacture. However, the shelf-life can be extended if stored well sealed above 50F. After 3 years, we recommend pre-testing a small sample prior to use. 

Batch code: X(YEAR) XX(MONTH) XX(DAY) X (INTERNAL CODE).

The batch number is a 6-digit code that is associated with the product's manufacture date and is typically located on the bottom of the container. 

Batch code: X(YEAR) XX(MONTH) XX(DAY) X (INTERNAL CODE)

Example: A product with the batch code #806141 was manufactured on June 14th, 2018.
