The heart of the WEST SYSTEM family of products, 105 Epoxy Resin is used in a wide variety of boat building and repair projects.
105 Epoxy Resin is a clear, light amber, low-viscosity liquid epoxy resin formulated specifically to wet out and bond with wood, fiberglass and a variety of metals. Multiple coats of a 105 Epoxy Resin create a superior moisture barrier and a tough, stable base for paints and varnishes. 105 Epoxy Resin is formulated without volatile solvents and does not shrink after curing. It has a relatively high flash point and no strong solvent odor, making it safer to work with than polyester or vinylester resins. With roller application, it possesses thin-film characteristics such as excellent flow out and the ability to self level without fish-eyeing. It cures clear and when altered with available additives can be easily sanded and shaped.
Choose from a variety of additives to customize the mix.
105 Epoxy Resin can be mixed with a variety of fillers and additives to suit specific needs, such as sag resistance, sandabilty or to increase its strength. Specific fillers also can be used to convert 105 Epoxy Resin into an excellent adhesive to suit a wide variety of bonding needs.
Speed up or slow down the reaction with available hardeners.
The cure rate of 105 Epoxy Resin can be adjusted to ambient temperature and desired working time. Three hardeners are offered: 205 Fast, 206 Slow, 209 Extra Slow and 207 Special Clear Hardener. 105 B-Size Epoxy Resin (Model 318352, shown above) should be paired with a B-size container of 205, 206, 207 or 209 Hardener.
