Tip for today.Epoxy.com Novolac Epoxy

June 28, 2012

Tip for today:  Epoxy.com #633 has excellent chemical resistant properties. http://www.epoxy.com/633.aspx We recently had an inquiry with the installed product coming in contact with hundreds of gallons of sulfuric acid in a major spill situation.  We were contacted to see if Epoxy.com #633 had been compromised. The answer is no.  As long as the material has been properly installed without pinholes, all that is required is decontamination of the exterior surface of Epoxy.com #633 coating.  No removal or reinstallation of Epoxy.com # 633 will be required. Epoxy.com #633 is specially formulated to prevent a spill from become a catastrophe.

That was a great question.  Please keep your questions coming.

Epoxy Education- The Strengths of Epoxy

Epoxy Educational Pages Anouncement:

The newest addition to Epoxy.com Education Pages is “Epoxy Resin Strengths Explained” which explains the 4 primary strengths that are very important for most civil and mechanical engineering applications of epoxy: compressive strength, tensile strength, flexural strength, and bond strength. “Epoxy Resin Strengths Explained” also discusses the test methods to measure these strengths.


Pot Life of 100% Solids Epoxy

June 7, 2012

As the Technical Support Director of Epoxy.com  I get a lot of email and phone calls about how to work with the relatively short potlife (typically 30-40 minutes) of 100% Solids Epoxy and similar resin systems.

It is important to understand that  Epoxy (and epoxy like resins) generate their own heat when mixed. So larger batches of epoxy  will generate more heat then smaller ones. The result of this is that larger batches of epoxy set faster than smaller batches. Start by mixing smaller batches of epoxy and then increase your batch size slowly.

To give you longer working times:

  • Make small batches that you can use in about 1/2 the working time of the material.  That will give you a little wiggle room and it will make your epoxy easier to use.
  • Be sure the product is cool when you mix it.  For best handling properties I like my material in the upper 60’s or lower 70’s. F.
