How to Safely Store Epoxy

If you are not familiar with the appropriate measures, safe epoxy storage can be just as precarious as epoxy application. Powerblanket is here to help you understand how to store epoxy in large quantities, such as in drums and barrels.

Epoxy Storage Conditions

If storing epoxy in large quantities, and this goes for other resins similar to epoxy, make sure that you are storing these chemicals both safely and efficiently. Storing epoxy for long-term warehousing means that you’re going to be storing it in large containers, probably barrels or drums. In fact, bulk distribution of epoxy is often accommodated by storing the chemicals in 55-gallon drums.

How to Store Epoxy Tip #1:  Temperature

Store two component epoxy resin systems between 65°F – 90°F. Refrigeration will not enhance the storage stability of two component epoxy resin systems. Use cooling measures if ambient temperatures exceed those recommended above.  Most two-component epoxy resin systems are naturally susceptible to crystallization, especially at temperatures below the recommended storage temperatures.  Containers placed near outside walls or on the floor will often be at a lower temperature than room temperature.

Never store epoxies where temperatures are close to freezing. Learn more about epoxy warming blankets here.

How to Store Epoxy Tip #2:  Clean and Dry

Store epoxy (and epoxy hardeners and curing agents) in clean dry areas with adequate ventilation. Because heat is the catalyst of epoxy curing, do not store near heat sources. Securely fasten all lids to prevent foreign matter contamination and moisture entry.

Sometimes sealed containers and dry environments can be easier to provide than an ideal temperature range. Epoxies are very temperature sensitive, and maintaining the ideal temperature for storage can be tricky when you’re keeping the chemicals in bulk storage units during winter months. This will either necessitate a nice and toasty warehouse, or else additive measures for storage efficiency—such as drum insulators and drum heaters.

How to Store Epoxy Tip #3:  Clean Up

Here are the proper steps to take when in contact with epoxy, whether accidentally or as a simple byproduct of application procedures.

  1. Wear protective gear. Whether you’re handling epoxy in drums for storage purposes or are applying it as a coating or resin, you need to always wear your protective gear.
  2. Thoroughly clean or dispose of tools and empty storage drums.
  3. Wash any clothes that have come in contact with the epoxy and shower if needs be. 

How to Store Epoxy Tip #4:  Disposal

Dispose drums legally and safely once you are done with them. If you finish a job and you still have some epoxy left in the can, consider whether you really need dispose of it.  Unused resin and hardener both have a long shelf-life. A considerable amount left in the drum could be useful on future projects.

However, if it is time to get rid of it, here’s how to dispose of PRO-SET or WEST SYSTEM epoxies safely:


  1. Mix epoxy correctly. If the resin and hardener are combined at the right ratio, cured epoxy is not hazardous.
  2. Ensure unwanted epoxy is cured and containers are empty. If you want to get rid of a used epoxy container, make sure it’s as empty as possible – ideally containing no more than 3% of the total capacity.
  3. Dispose of cured epoxy and containers with your normal garbage. Once you’ve followed steps 1 and 2, everything should be able to go in the garbage can.  (Regulations on hazardous waste differ depending on where you live, so be sure to check with your local government for more detail.)


Epoxy is a strong material with as many sensitive qualities as it has potent characteristics. However, when handled appropriately, epoxy is a very handy and valuable material.

Drums, Totes and Barrels: Protecting Your Bulk Storage

style Drum Heater

Is cold weather ruining your product? Is your warehouse cold and drafty? Are your materials becoming too thick to flow? Do you live in Boise, Idaho? Scratch that last one. Whether you’re storing food, paint, chemicals, or spray foam, keeping your assets in bulk containers can have major limitations. Depending on the specific characteristics of your materials, some storage options have to be chosen very carefully. Let us help you get started.

Bulk Storage in Drums, Totes, and Barrels

IBC totes, barrels, and drums have something in common: they’re containers for storing bulk materials. Wahoo! Let’s look into some specific product cases that might require some extra thought when storing.

Food Storage

In the case of food stored in drums, freeze protection might not be a real concern for some. After all, some foods must be refrigerated until they are ready to be consumed (cue Ben & Jerry’s). However, other foods thicken or spoil if they get too cold. Heating for large quantities of food may be a matter of consideration for you.

Paint and Chemicals

On the other hand, if you’re storing paint or sensitive chemicals in barrels, then freeze protection might be one of your main concerns. In the case of spray foam stored in IBC totes, maintaining an ideal temperature is vital. These solutions, which go beyond heat, will help you maximize your storage and application efficiency.
Whether it’s for freeze protection or preparatory heating, drum, barrel, and tote heaters will keep your storage at an ideal temperature for application. Some heating products for bulk storage only offer insulation for drums, barrels, or totes. Others offer both insulation and heat transfer. In the case of temperature sensitive materials, the latter is preferable. So what is the best option?

Need Custom Heating for Your Equipment? Answer These Questions

Do you need custom heating for a specific and unique application? Although there are various standardized heating solutions available, to determine the right solution, either standard or custom, a few initial questions need to be understood. The first of the discovery questions is to identify the desired result of the application which is generally one or a combination of the following:Custom Heating

  1. Freeze Protection:  Generally to protect from the elements or cold climate
  2. Temperature Maintenance:  Maintain a specific, constant and optimal temperature
  3. Added heat or Increase Temperature:  Add heat  and Increase temperature higher from starting point

For example, a pipe heating application may require higher energy/wattage to thaw a frozen pipe and then settle to a moderate power/wattage for continual freeze protection and flow control long term.

An epoxy/composite curing application may require pre-heating at higher temperatures prior to the epoxy being applied and then maintained at a higher temperature for optimal curing.

Begin with These Steps

  • Gather as much information as possible using the Custom Application Questionnaire. Be thorough.
  • The dimension needs to be as built, not a CAD drawing .  ALL dimensions must be submitted to the custom team for quote.
  • Once quote is accepted and PO is sent, engineering will begin.
  • Custom products will normally be completed within two weeks.

Custom Application Questionnaire

Once we understand the problem, these types of questions reveal the best solution:

  1. Which of these best describes the system requiring Cooling: drum/bucket, tote, tank, gas cylinder, pipe, flat surface (vertical or horizontal?), other?  
  2. Can you provide drawings and/or photos?  
  3. What are the critical dimensions of the system?  
  4. What material is the container or surface made of (i.e. tank wall, drum wall)? How thick? 
  5. What is the substance being Cooled (i.e. water, oil, pipe contents, concrete, frozen ground)? 
  6. Is this a flowing system? If so, what is the flow rate (include units, gpm, cfm, etc.)? 
  7. What is the expected ambient temperature (include units, °F, °C)? 
  8. What is the maximum expected wind velocity (include units, mpg, km/h, etc.)? 
  9. Are there other environmental conditions that may be relevant? 
  10. What is the beginning temperature of the substance or contents (include units, °F, °C)? 
  11. What is the desired final temperature of the substance or contents (include units, °F, °C)? 
  12. What temperature range is acceptable? 
  13. Are there upper or lower temperatures where the substance or contents will be damaged? 
  14. Is there a time frame requirement for the initial cool down? 
  15. What power source is preferred (120, 208, 240, DC)?  
  16. How far away is the power source (cord length)? 
  17. Do you require UL/CSA certified products? 
  18. Is your location considered hazardous (Class I Division 2)?
  19. How many units do you need now and in the future? 
  20. What is the required delivery date? 

Custom Heating Case Study

Powerblanket completed a project for a large chemical company to solve freeze protection problems. The company stores a chemical solution in large 4,000 to 8,000 gallon stainless steel tanks. Their customers live in various climates throughout North America. This solution is water based and freezes at roughly 32°F.  This company needed freeze protection and to maintain regular temperatures between 40°F -70°F.

The question became, “How do we provide a ‘one size fit all’ customized solution for various climates?” Powerblanket created a modular custom design, adjustable by region and tank size, that came in two pieces.

Powerblanket engineers calculated the amount of heat and insulation required to combat freezing temperatures and wind chill to maintain optimal temperatures in these various climates. What appeared to be a complicated application turned into a simple and effective custom solution.

So many industries need heating solutions, and not just during the cold months either. Epoxy curing, chemical storage, viscosity maintenance, food preparations, concrete curing, and much more all benefit from innovative temperature regulation year round.
