FAQs

What is the shelf life of your epoxy resin products? ›

The minimum shelf life is three years after the manufacture date for resins and two years after for hardeners.

The shelf life of MAS epoxy resins and hardeners is at least one year in sealed containers, but the material can last much longer when stored between 60-90°F in a dry place. The product should be stored indoors, on a raised surface off the floor and away from exterior walls.

It is also a good idea to store epoxy resin in its original container in order to protect it from contamination and to ensure that it is stored correctly. Shelf life of product in original closed containers is one (1) year.

Properly stored at room temperature (73°F/ 23°C), Smooth-On® epoxy products have a shelf life of 36 months from date of manufacture in unopened containers. For Bell Spec certification, Metalset A4 shelf life warranty is limited to 18 months. For all other certifications, the warranty for Metalset A4 shall be 36 months.

STORAGE SHELF LIFE Devcon Epoxy Adhesives should be stored in a cool, dry place when not used for a long period of time. A shelf life of 3 years from date of manufacture can be expected when stored at room temperature 22ºC in their original containers.

Epoxy shelf life can last many years when resin and hardener are properly stored at room temperature and in closed containers to prevent contamination. Those who have used polyester resins know that its shelf life is only about six months before it turns to a useless jelly-like substance.

Deionization (DI) resin lifespan typically lasts 5 to 10 years. However, if any of the four primary factors cause your resin to foul prematurely, it could lead to a deterioration in your deionized water quality.

Technically, epoxy resin does not expire in the traditional sense; instead, it has a 'best before' date.

The longevity of an epoxy floor system will vary based on thickness, use and maintenance. Typically, epoxy floors last between 10 and 20 years; much longer than a painted concrete floor, which will chip and wear quickly in high-traffic areas.

The expiration date of a resin composite is an important factor to be considered. Theoretically, if used after the specified expiration date, material properties may be affected. From a clinical point of view, this may lead to failures such as fracture, excessive wear, and discoloration.

How to tell if epoxy is bad? ›

All solvent-free epoxies have essentially unlimited shelf lives so long as they are stored in sealed containers. The resin may crystallize or the hardener may darken (YELLOW) but this does not affect its performance. If the material is more than a year old do a test to satisfy yourself that it cures properly.

Epoxy Putty has a shelf life of 12 months if kept in the original SEALED CONTAINERS. Keep in cool, dry frost free conditions in original sealed containers. Protect from freezing.

Sanding Epoxy Resin With a Sanding Block

Begin with a lower grit waterproof sanding sheet(around 80-120 grit) attached to your sanding block. This coarse grit helps remove any major bumps, drips, or imperfections from the cured resin. Sand the resin surface using gentle, circular motions or back-and-forth strokes.

For our UltraClear Table Top Epoxy: A shelf life of one year. For our UltraClear Deep Pour Epoxy: A shelf life of one year.

Soft or sticky epoxy resin can be caused by a variety of issues, including improper mixing, high humidity, and high temperatures. Once passed the curing time, if you observe that your resin remains sticky, it is very likely that you did not follow strictly the ratio or mixing process indicated.

Epoxy resin and hardener formulations have a long shelf life compared to many polymers. The minimum shelf life for the standard INF and LAM products is 3 years for resins and 2 years for hardeners (with the exception of LAM-251-HT).

Technically, epoxy resin does not expire in the traditional sense; instead, it has a 'best before' date. Even past this date, properly stored epoxy resin can still be used. It'll likely be less effective than it was in the past.

Storing Art Resin: Can be kept for greater than 12 months, if kept in original containers, with lids tightly closed. Product to be stored in a dry dark room/cupboard at temperatures between 15 and 30ºC, and out of direct sunlight.
