Product Information
407 Low-Density filler is a blended microballoon-based filler used to make fairing putties that are easy to sand or carve. Reasonably strong on a strength-to-weight basis. Cures to a dark red/brown color.
West System epoxy is a high-quality, two-part epoxy that is easily modified for a wide range of coating and adhesive applications. It is used for construction and repairs requiring superior moisture resistance and high-strength. It bonds to fiberglass, wood, metal, fabrics, and other composite materials, and is especially suited for marine applications.
All epoxies are not created equal. There are big differences in formulations, quality of raw materials, the suitability for building and repairing boats and the toughness to stand up to marine conditions. It's easy to market an off-the-shelf industrial epoxy product as a marine epoxy, or formulate an epoxy with one or two favorable characteristics, while sacrificing other important characteristics.
Good science is at the heart of WEST SYSTEM epoxy. Comprehensive testing is the basis of that science and is essential for the development of improved epoxy formulations and better construction and repair methods. Twice as many people at Gougeon Brothers are involved with technical service and testing than with marketing. When professionals need answers to tough questions, they come to us. They know our answers are based on good science and hands-on experience, not on marketing.
105 Resin is the base material of the WEST SYSTEM family of products, on which all of the WEST SYSTEM compounds are built. The resin is a clear, pale yellow, low-viscosity liquid epoxy resin. Formulated for use with WEST SYSTEM hardeners, it can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance. It is designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals.
An excellent adhesive, 105 will bridge gaps and fill voids when modified with WEST SYSTEM fillers and can be sanded and shaped when cured. With roller applications, it has excellent thin-film characteristics to flow out and self-level without "fisheyeing." The resin cures clear so that you can achieve a natural finish when coating with varnish. It has a relatively high flash point and no strong solvent odor, making it safer to work with than polyesters. Resin viscosity is approximately 1000 cps at 72°F (22°C).For each container size of resin, there is a corresponding sized container of hardener and a corresponding mini pump size. When purchasing resin, hardener and mini pumps, be sure all containers are labeled with the same "group size" letter (A, B or C).
