Installing Epoxy in Coolers and Cold Temperature

Extend Epoxy Installation Season into Winter

I have spoken on this subject here before but this time of year I get a lot of calls and emails about installing epoxy in cold temperatures. Our company started out as an installation company in Vermont. Summers are very short and winters are very long in Vermont. To stay a viable company, we had to figure ways of working through the winter.

Tenting and heating areas during the winter is time consuming and expensive. The solution is found in resin products that will set in low temperatures. The most durable and cost effective options of installation at cold temperatures is Epoxy and Methyl Methacrylate.

Cold Temperature Cure Resins can also be used as a super-fast setting Resinous Mortar or Coating at normal temperatures. Our Cold Temperature Cure Resins used at normal temperature give you quick turnaround time for small jobs, or larger jobs that require a short turn-around time.

Cold Temperatures Epoxies

Cold Temperature Cure Epoxy Resins allow installation to be done at low temperatures as low as 35°F., (although it sets a lot faster at 40°F) expanding your epoxy coating and epoxy flooring installation season. Epoxy.com Cold Temperature Cure Epoxy Resins can also be used in cold storage areas like food processing areas, where the temperature cannot be raised higher than 35° F or so. Normal cured epoxy typically requires 50°F or more.

Depending on how you mix the aggregate into the products below, they can be used as a mortar for overlays, or a grout for sealing between other hardened construction materials.

Commonly Used Cold Temperature epoxies

Product #1 Cold Temperature Cure Epoxy Coating is 100% solids and specially formulated coatings for cold temperature applications. Cold Temperature Epoxy Coating #1 is able to cure at temperatures as low as 35°F. It is has Zero (0) VOCs. Since it has no VOCs, it has no solvent so it meets the strictest possible standard for a low VOC coating. It is often used in coolers and food preparation areas that require constant low temperatures. Product #1 Cold Temperature Cure Epoxy Coating is also frequently used in room temperature applications to meet super-fast cure, limited shutdown needs.

Product #10 Cold Temperature Curing Epoxy Mortar Resin – This product has a low modulus of elasticity (flexibility) and is Low Viscosity. The low viscosity allows heavy loading of the right fillers. The heavy filler loading helps not only to save money, but helps to maintain better thermal coefficient with respect to concrete and steel. The low modulus of elasticity prevents it from being brittle making it less vulnerable to thermal coefficient differences. It also gives it better impact resistance.

Oil Saturated Concrete

 

Oily contaminated concrete is very difficult to bond to, but it can be done with special care and Epoxy.com Product #201 Oil Stop Primer.  Plant floors, warehouse floors, commercial, and residential garage floors can all have this problem.  Here is a typical question that I get about oil contaminated floors:

“We were looking at your product because we have a floor in a maintenance garage that is pretty well soaked with oil.  A new tenant is going into that space so we know that there needs to be something to allow the new floor to stick and to stop the odors.”

Here is my typical response:

Is the oil saturation petroleum oil? If so you need to:

  1. Degrease the floor
  2. Mechanically clean the floor – www.epoxy.com/surfaceprep.aspx.
  3. Apply 1 coat of Epoxy.com Product #201 – www.epoxy.com/201.aspx – at a rate of 200-320 SF per gallon.
  4. Inspect for bond the next day. If bond fails remove the loose #201 and go back to step one.
  5. If bond is good check for oil on top of the primer.  If there is oil on top of the #201 and it is well bonded remove the oil with xylene or other effective degreaser.
  6. Coat with 2 coats of Epoxy.com Product #2 – www.epoxy.com/2.aspx.

I like the Product #2 for these applications because it is very resistant to petroleum oils. Depending on your specific application the material you use over the #201 can be a number of different flooring, coating systems or chemical resistant epoxy floor systems.

July 10, 2015

The problem with getting superior adhesion to difficult to bond to surfaces like stainless steel and aluminum has been solved

 

The Technical Support Department here gets many calls from people needing help in selecting the right coatings for a variety of metals and difficult to bond to surfaces. Carbon steel is easy to bond to when it is well sandblasted and you use one of our high end epoxy coatings like Product #2 Chemical Resistant Epoxy. What if the carbon steel cannot be sandblasted and can only be ground? What about stainless steel and other difficult to bond to metals and coatings? Epoxy.com Product #660 Universal Primer and Finish was designed to solve these bonding issues.

Product #660 Universal Primer and Finish is a one component, moisture cured polyurethane aluminum filled primer and coating. Product #660 Universal Primer has a low viscosity, with high “wetting” characteristics, and blistering resistance. This makes Product #660 Universal Primer and Finish a superior primer. It can also be used as a finish coat. Epoxy.com Product #660 Universal Primer and Finish undergoes a rapid molecular weight change as it polymerizes into a high molecular weight finish with excellent corrosion and abrasion resistance.

Epoxy.com Product #660 Universal Primer and Finish is an ideal barrier coat when upgrading existing finishes to strong urethanes, coal tar epoxy, etc. The low solvency power of Epoxy.com Product #660 Universal Primer and Finish enables it to be applied over most types of coatings without causing lifting. A test sample should be made to confirm adhesion. Most generic types of chemical or conventional coatings may be applied over Epoxy.com Product #660 Universal Primer and Finish with excellent adhesion.
