Will It Stick?

By Mike Barnard

Many times each day we get questions about sticking to various substrates.  Most questions are on something that we have already tested, so we check our large database and advise on how best adhere to the surface.  Other times the request is unique and we are unsure if WEST SYSTEM® Epoxy will stick to it or not.  In the event we do not have any experience bonding to a material, we recommend testing adhesion.  Many times this means gluing a wood block to the surface, then pulling the Continue reading

Testing, Testing, 123

By Julie Van Mullekom

By now most of you know that we are the manufactures of WEST SYSTEM® Epoxy. But you may not know what is involved in the manufacturing and more specifically, the formulating of WEST SYSTEM. It’s not just slapping some chemicals together and then packaging it up into a pretty box. To date we have performed thousands of tests, generating thousands of test results. Continue reading

A Better Way to Prepare Laminates

By Tom Pawlak

During a recent inspirational hardware store visit, I discovered a rotary wire brush made by Norton™ called the Rapid Strip Brush™. It is used with an electric drill and produces results comparable to bead blasting or a needle scaler. The package says it can be used to abrade metal, masonry and fiberglass. I immediately thought of a fiberglass application that I wanted to try it on. Continue reading

Testing DCPD Blend Laminates

By Tom Pawlak

Gougeon Brothers recently did R&D testing for a manufacturer who wanted to know if WEST SYSTEM® epoxy could effectively repair injection-molded parts made with fiberglass and dicyclopentadiene (DCPD) blended polyester resin that included an internal mold release. The hoods and decks for many jet skis and snowmobiles are made with this material.

DCPD blends in polyester cause it to cure rapidly and cross-link thoroughly. This feature helps to reduce emissions from the resin but makes it difficult to repair Continue reading

Gluing Plastic Dimensional Lumber

By Patrick Ropp

More people are using recycled plastic/wood composite lumber for decks and other various projects. Although each manufacturer of recycled plastic lumber has his own blend, we found that most are using very similar ingredients: an equal amount of melted recycled plastic mixed with recycled wood chips or sawdust and then extruded in the form of dimensional lumber. Since the wood is encased in plastic, the plastic/wood composite boards are supposed to last longer than traditional decking materials and carry a good warranty. Many of these boards are not intended for use as structural members, but they Continue reading
