At Gougeon Brothers Inc., customer service and support are paramount. Throughout the decades (five strong and counting), we’ve built our WEST SYSTEM® product line on a model that places customer satisfaction at the forefront. Many WEST SYSTEM users know first-hand that we strive for customer success no matter the project. Our customers’ projects range across an extremely wide spectrum. What many users may not know is the extent of product support that grinds away behind the scenes before a batch of our epoxy even hits the retail shelves. I’ll provide a look at just one of our churning gears that isn’t so obvious at first glance-quality control (QC). Continue reading →
I’m fast approaching my 22nd year of working here at Gougeon Brothers, Inc. From my first day on the job, I have lived the controversy surrounding penetrating epoxies vs. high-solids epoxies in general and WEST SYSTEM® Epoxy in particular. I have met with the formulator and founder of a popular brand of penetrating epoxy and talked to him many times over the years. He is a nice fellow and passionate about his product, but in the end we had to agree to disagree. Continue reading →
Wood has always been used in fiberglass boat construction, in stringers and oftentimes as core in high compression areas such as under cleats, stanchions and winches. Wood works great in these applications but we all know that the big problem with wood is the fact that it rots if it gets wet. Here at Gougeon Brothers, Inc. (GBI) we have spent long hours writing manuals and training people to use proper techniques using epoxy to keep wood dry and strong. Continue reading →
During warm summer months, handling characteristics of WEST SYSTEM Epoxy will be different than at other times of the year. Our cure times are based on an ambient temperature of 72°F, but in warmer temperatures the epoxy will cure faster. There are some steps you can take to ensure good results when using WEST SYSTEM Epoxy in warm environments. Continue reading →
There are some myths out there as to whether you can apply gelcoat over epoxy. Andy Miller addresses the issue. He has a great understanding of WEST SYSTEM Epoxy, having used it for years as owner and chief repairman of Miller Boatworks in Herbster, Wisconsin. Andy knows his stuff. What’s even better is that, when he’s unsure about a detail, he contacts us for the right answers. Continue reading →
Because a newer epoxy formulation we offer is great for aluminum adhesion, we stopped offering the 860 Aluminum Etch Kit in the WEST SYSTEM product line in 2015. Before making that decision we ran a series of tests that compared bond strength of 105 Resin/206 Hardener and G/flex 650 Epoxy on aluminum surfaces prepared a variety of ways. As usual, we used the PATTI (Pneumatic Adhesion Tensile Test Instrument) to test aluminum adhesion. Continue reading →
When mixing larger batches of resin and hardener, pot life— or the amount of time that elapses before the epoxy hardens in the container—is very important. You need to estimate how much mixed epoxy you will use in a certain amount of time. Variables that affect this calculation include temperature, volume, surface area, hardener speed, the insulating quality of the substrate the epoxy is exposed to, and any fillers used.

While most of our customers are successful when using WEST SYSTEM Epoxy to repair damaged fiberglass, we have become familiar with some common mistakes that are easily preventable. These mistakes are made by both professionals and amateurs. The information discussed in this article is available in our Fiberglass Boat Repair Manual and WEST SYSTEM User Manual, and on the WEST SYSTEM website.

When most epoxies are exposed to the atmosphere (especially cold and damp conditions) a secondary chemical reaction can occur at the surface of the epoxy, leaving a waxy looking by-product called amine blush. This water-soluble film appears only at the end of the cure cycle, and never at all when WEST SYSTEM® 207 Special Clear Hardener is used.
Much ado is sometimes made regarding blush, but the reality is, it’s easily avoided and easy to remove. Continue reading →
