It pairs with WEST SYSTEM 105 resin at a 5:1 ratio, curing predictably at room temperatures above 60°F, and is adaptable with fillers and fiberglass for versatile structural and protective uses. ## Description Product description Popular Uses of WEST SYSTEM Epoxy Bonding & Filleting WEST SYSTEM Epoxy is excellent for structural bonding and fillets. It can be easily thickened with a number of fillers to modify consistency and strength. There are two types of structural bonding that can be done with epoxy. TWO-STEP BONDING is the preferred method for most situations because it promotes maximum epoxy penetration into the bonding surface and prevents epoxy-starved joints. SINGLE-STEP BONDING is appropriate when joints will have minimal loads and excess epoxy absorption into porous surfaces is not a problem. In both cases, epoxy bonds best when it is worked into the surface with a roller or brush. Coating, Laminating & Clear Finishing COATING AND LAMINATING are popular uses of WEST SYSTEM Epoxy. Epoxy wets out fiberglass cloth, protecting the substrate while letting its beauty shine through. We recommend WEST SYSTEM 105 Resin with blush-free, water-clear 207 Special Clear Hardener for bright finishes and clear coats. COATING involves rolling the epoxy onto a surface with a foam roller, applying it with a brush, or spreading the epoxy over the surfaces with a plastic spreader. . There are two methods for laminating with fiberglass and epoxy. THE DRY METHOD refers to placing the cloth over a dry surface, wetting the cloth with epoxy and spreading the epoxy over the cloth, smoothing it as you go. THE WET METHOD involves applying the cloth to an epoxy-coated surface after the wet-out coat becomes tacky, which helps it cling to vertical or overhead surfaces. This method makes it more difficult to position the cloth, so the dry method is the preferred, especially when using with thinner cloth. Clear Casting & Pouring CASTING AND POURING are best done with WEST SYSTEM 105 Resin and 207 Special Clear Hardener. AVOIDING UNCONTROLLED EXOTHERM is important, as this heat reaction can quickly spoil the casting. Epoxy cures by exothermic (heat) reaction. That heat must be kept under control when when creating a thick casting (greater than ¼”). For thick castings, add epoxy in multiple layers . When the first pour is tacky like the back of masking tape, a second pour can be made. When the epoxy cures enough to become tacky, it means the previous layer has begun to cool down and will not contribute heat to the next layer. Adding another layer at this stage allows you to skip any surface prep. If the poured epoxy casting cures past the tacky stage, allow the epoxy to finish curing then sand ot dull and clean the surface before applying the next epoxy layer. This will ensure good adhesion between layers. Versatile, reliable WEST SYSTEM products WEST SYSTEM offers high-quality epoxy resins, hardeners, fillers, and additives.

Fiberglass Boat Repairs & Construction This vintage 15' Larson Thunderhawk was repaired with WEST SYSTEM Epoxy. Damage from collisions, groundings, the forces of nature, and aging make it common for fiberglass boats to need repairs. Effectively repairing a fiberglass boat requires a superior structural adhesive, that adheres to polyester resin, fiberglass, wood, metal and other materials. Unlike polyester resin which can shrink from 5% to 8%, creating stress concentrations at the repair joint, epoxy doesn’t shrink. It's also a more effective moisture barrier. Epoxy forms a tenacious mechanical bond with cured polyester and other materials in secondary bonding. Since epoxy is more durable than polyester, the epoxy repair may be even stronger than the original structure. Ease of use, ready availability, safety, and easy access to how-to information makes WEST SYSTEM Epoxy excellent for fiberglass boat repair. Wooden Boat Construction & Repairs This strip canoe was built with WEST SYSTEM Epoxy. Wood is the primary building material for many of today’s most durable and most beautiful boats, whether canoes, kayaks, dories, sailboats or power boats. Many of the wood/epoxy construction techniques that have made modern wooden boats so successful can also be applied to the repair of older wooden boats with excellent results. Gougeon Brothers, Inc., the company that has been formulating and manufacturing WEST SYSTEM Epoxies since 1969. They pioneered the use of epoxy to enhance wood's natural structural properties. Ease of use, ready availability, safety and easy access to instructional materials makes WEST SYSTEM Epoxy a great choice for wooden boat construction and repairs.
