Can I Use an Expired Product?
Often yes, after a test. At Rivelec, we consider a product stored at room temperature in its unopened original packaging safe to use up to one year after its expiration date. We recommend that you test it first. Past the date, we no longer guarantee the performance given on the technical sheet.
Where the Date Is and What It Means
The expiration date is printed on the cartridge, or under the pot. It falls 24 to 36 months after manufacture, depending on the product. This applies to a product kept in its original packaging, well closed, in a dry place between 15°C and 25°C. We have also confirmed the conformity of products made more than 5 years earlier, untouched and stored in nominal conditions.
How to Test It
- Look at the product, because a change in appearance or consistency is a sign of deterioration.
- Extrude a test drop and check that its color is uniform.
- Time its polymerization, as an abnormally long time is a sign of deterioration.
- Take a trial impression on a reference part before any real inspection.
What Shortens the Life of a Product
Wide temperature variations and extreme temperatures below 0°C or above 55°C shorten the life of a product. Swapping the caps between the two components or leaving a cartridge badly closed contaminates the components and alters the 1:1 mix.
