Built in 1957, my 15′ Larson Thunderhawk Jr. is a fiberglass runabout reborn. I launched her into the waters of Grass Lake, in Fox Lake, Illinois in late August 2010. But before this happened, the boat underwent a major restoration. I purchased this boat in August of 2009, after it sat idle for several years, collecting dirt, rainwater, leaves and snow. All that remained was its shell,
I purchased this boat in August of 2009, after it sat idle for several years, collecting dirt, rainwater, leaves and snow. All that remained was its shell, motor, and a rusted trailer. I found a group of Larsen enthusiasts who helped me locate my boat’s original specs, drawings, and
We spend a good amount of time doing everything we can to inform our customers how best to make WEST SYSTEM® epoxy stick to wood, metal, and even plastic, or underwater with the introduction of G/flex 650 and 655. Still, there are many instances when you don’t want the epoxy to stick to one surface or another. This is where mold release agents come in very handy.
We formulated Six10 Epoxy to work when dispensed from a u-TAH chambered cartridge with a mixing wand. Putting epoxy resin and hardener into a single cartridge was an idea we had years ago, but until the u-TAH cartridge was developed, the technology was never around to do it. Once that technology became available, it was time to formulate Six10 Thickened Epoxy Adhesive. Continue reading →
Sealing and priming a surface prior to applying the final finish affects how it ages, and how it ages has everything to do with the way the finish is anchored to the wood. Sealers and primers are often taken for granted; we simply read the can and follow directions. There are so many reasons for using a sealer and many methods for applying them. Let’s look at what we learned while sealing Sparks, the electric launch I built. Continue reading →
Are you the kind of person who just can’t get enough of a good thing? Looking for a better way to squeeze out that last little bit of G/flex 655 Thickened Epoxy Adhesive from your tube rather than resorting to pliers, a vise, or maybe even Grandma’s rolling pin? Maybe you’d like to get a fatter bead of adhesive or your tube is a bit clogged. Boy, do we have some easy and inexpensive tricks for you! Continue reading →
While WEST SYSTEM® epoxy has a long shelf life, age will eventually affect its handling characteristics and cured strength. When stored for very long periods, hardeners may turn darker (reddish to purple), become thicker and give off more odor. 105 Resin may lose some clarity and also become slightly thicker. Use extra care when mixing age-thickened products (stir extra thoroughly), and if color and/or clarity are crucial to your project, buy some fresh resin and hardener for best results. 207 Special Clear Hardener is specially formulated for clarity and flow.

Over the course of the last couple of years, Gougeon Brothers Inc. has partnered with Waste Management Inc. to implement a comprehensive recycling program that has been both simple and effective. We are now recycling emptied plastic and metal epoxy containers, shrink wrap from bulk packaged items, dispensed adhesive cartridges, cardboard boxes, miscellaneous soft and rigid plastic items, office paper, magazines, etc. Continue reading →
In this article, I’ll describe our standards for testing epoxy and how we go about testing epoxy to determine its handling characteristics and cured physical properties.
Epoxy 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 epoxy, 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 article, White Oak Redux (Epoxyworks 34), generated two responses we wanted to share. We consider ourselves students as well as tech advisors and so we’re always open to learning something from others. Our readers are generally pretty savvy people, and when they take the time to write us a thoughtful letter, we feel compelled to share what we learn from them with the rest of our readers.

Inspired by an old Boatbuilder article by Captain James R. Watson, my father and I built our own deluxe epoxy caddy, which we call the Coupe de Ville of Epoxy Caddies. My dad 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. Continue reading →
