Epoxy Compression Test in Progress

Determining Epoxy’s Physical Properties

BY MIKE BARNARD

In this article I’ll describe our standards for testing epoxy and how we test epoxy to determine its handling characteristics and cured physical properties.

Testing Standards
These are the standards we follow no matter which epoxy we are characterizing.

Two-week room temperature cure
After proper metering and thorough mixing epoxy will continue to cure after it has solidified, until all amines have paired up. Over years of testing we have found that two weeks of curing at room temperature, which we define as 72°F (22°C), is a good indication of its full strength. Continue reading
