WEST SYSTEM #105, EPOXY RESIN-GROUP SIZE "B"

Description

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). Group size quantities and coating coverage: WEST SYSTEM epoxy resin and hardeners are packaged in three "Group Sizes." 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).Shelf life: If the containers are kept sealed when not in use WEST SYSTEM resins and hardeners should remain usable for many years. Over time, 105 Resin will thicken slightly and will therefore require extra care when mixing. Hardeners may darken with age, but physical properties are not affected by color. Mini Pumps may be left in containers during storage. It is a good idea, after a long storage to verify the metering accuracy of the pumps and mix a test batch to assure proper curing before applying epoxy to your project. .98 U.S. GAL.(3.74L).
