On January 1, 2015, we began selling a new WEST SYSTEM Epoxy pigment. We already had the 501 White Pigment and the 503 Gray Pigment, so it seemed right to introduce our new 502 Black Pigment. Just like the 501 and the 503, it alters the color of the epoxy mixture without affecting the cured physical properties. Similarly, the maximum acceptable loading is 3%. This is great for hiding a surface with a single coat of black epoxy. Adding more pigment will increase the opacity, but can skew the mix ratio because there is epoxy resin in the pigment.

The goal of fairing is to create a surface without bumps or hollows.
Fairing Compound should be of a consistency that can be troweled onto a surface without sagging. Add 407 Low Density or 410 Microlight filler to mixed epoxy, checking the consistency as you stir in the filler to determine if the mixture has the correct viscosity for your application.

G/5 Five-Minute Adhesive is a fast curing two-part epoxy that allows 3-5 minutes of working time. It has an ideal viscosity which allows it to penetrate porous surfaces yet is viscous enough to bridge gaps when gluing broken objects. It adheres to a number of surfaces including wood, ceramic, metal, leather, plaster, stone, fiberglass, glass, cork, some plastics and paper. G/5 is an excellent choice for quick repairs around the house, high-end crafts and much more. Continue reading

In January of 2015, we stopped offering the 860 Aluminum Etch Kit in the WEST SYSTEM product line. 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 adhesion. Continue reading

For some sailors, there is a common maintenance ritual that occurs every spring—repairing cracks where the leading edge of the ballast keel meets the hull. This annually reoccurring crack is sometimes referred to as a “Catalina Smile” because it often occurs on Catalina sailboats.
The crack can form due to a number of causes but probably the most common reason is the hull isn’t as stiff as when it was new. Continue reading

Surcease is a late ’50s International Flying Dutchman Class sailboat. The Mahogany hull was cold-molded in Holland and imported by Paul Rimoldi of Miami Florida. Mr Rimoldi made everything else, including many pieces of hardware. He raced the boat on Biscayne Bay into the ’60s and sailed it for many years. He rebuilt the boat in the late ’80s but died before he finished. We bought the boat in August 1992 from his widow and sailed it for almost a season before we discovered that the hull was in very poor condition; the Urea-resin glue between the veneers had begun to turn to dust. We stored the boat and bought another Flying Dutchman. Continue reading

I often get calls from a customer asking if his left over epoxy can be used for some small project around the house
The answer is yes, of course! Here are three projects that are perfect examples of what you can do with those partial cans of WEST SYSTEM® resin and hardener.

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. Continue reading

Last Father’s Day I received a new light and sleek bicycle from my family. It is by far the nicest bike I’ve ever owned. I enjoy riding it to work in the spring, summer and fall. Because it is so nice, I decided I didn’t want to bolt on the aluminum bracket used previously over the back wheel on my old bike. The bracket had served multiple purposes. It supported my travel bag and it acted as a fender to keep road water off my back while riding. I decided I would ride with a backpack instead to reduce bulkiness and thought it would be nice to make a lightweight fender that I could snap on for those rainy days. That would allow me to remove it for longer trips and on nice weather days. Continue reading
