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.
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

My father has grown very fond of WEST SYSTEM® Epoxy and his box of epoxy-related items has been growing at a steady rate. The overflow of his box in an already “treasure” packed garage emphasized his need for an organization and storage system for these materials. We have had several requests for this same type of solution lately, so I did some digging and found a great Boatbuilder article from 1986 written by J.R. Watson. Inspired by this article, my father and I built our own interpretation of the Epoxy Caddy.

WEST SYSTEM® epoxy has long been a popular choice for clear coating table tops. It works great as a buildup coat and a moisture barrier. It also showcases the beauty of wood grain and fiber weaves. Formulated with boat building in mind, WEST SYSTEM epoxy is not intended as a final finish coating. You may find it a bit more difficult to achieve a perfect surface with epoxy than with a coating formulated specifically for final finishing, such as varnish.
However, WEST SYSTEM offers some distinct advantages. It builds up quickly: a single coat of 105 Epoxy Resin® with 207 Special Clear Hardener® offers about four times the thickness of a typical coat of polyurethane varnish. WEST SYSTEM epoxy is also an excellent moisture barrier, stabilizing the surface so your final finish coat will look beautiful longer. Continue reading
