A question frequently posed to our technical staff is “can I thin WEST SYSTEM® epoxy so it will flow or penetrate better?” The answer to that question is “yes, but not without consequences.” Many of the advantages of thinning epoxy are offset by disadvantages in other areas of epoxy performance.
Adding a coloring agent to WEST SYSTEM® Epoxy is frequently done to make colored castings, highlight an epoxy coated surface, act as a colored base coat for paint, etc. Most powdered pigments are satisfactory, as are acrylic paste pigments and universal tinting pigment. Continue reading →
Use one full pumps stroke of resin for each one full pump stroke of hardener to get the proper resin-to-hardener ratio.
If you’re ever concerned that your pumps aren’t metering properly, simply mix a test batch of 3 pump strokes each of resin and hardener. Stir thoroughly and make sure it’s fully cured before continuing with your project. Continue reading →
This article about epoxy and oak was originally published in early 1995, and is shared at Epoxyworks.com for historical purposes. A dozen years after this article was written, we developed G/flex epoxies, which are rubber toughened to withstand shock, vibration, expansion and contraction. G/flex epoxies adhere tenaciously to many difficult to bond substrates, including dense and oily wood species like oak. Continue reading →

We frequently update these publications to give you easy access to the latest information on using epoxy for construction and repair. You’ll find these publications filled with explanations and illustrations covering virtually all aspects of marine repair with epoxy. Continue reading →
If you were to inquire about the physical properties of WEST SYSTEM® epoxy, you’d receive a physical properties data sheet. To some, the information is very meaningful, but I was having a hard time figuring out what all those tests and numbers meant and how they applied to my projects. After I found out for myself, I decided to write an article explaining how the tests are performed and what the resulting numbers mean. Continue reading →
Many materials used in large manufacturing processes and even small do-it-yourself jobs, emit volatile organic compounds (VOCs) and other air pollutants. Paints and other coatings, adhesives, resins and cleaning solvents are all sources of air pollution. Each product emits different types and varying amounts of air pollutants. Federal, state and local governments have passed legislation (e.g., the federal Clean Air Act) to reduce air pollution and prevent the depletion of the ozone layer by regulating the emission of air pollutants.
