Description

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 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. 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. WEST SYSTEM offers high-quality epoxy resins, hardeners, fillers, and additives. Developed by our in-house chemists, our formulations are proprietary, structural, and marine grade. These epoxies have set the standard for epoxy quality in the marine industry and beyond since 1969. Founded in 1969, Gougeon Brothers, Inc. (GBI) formulates and manufactures WEST SYSTEM products. In 2020, NSF International recertified GBI's ISO 9001:2015 status, which ensures consistency in epoxy formulation, production, packaging, and instructional materials. EPOXY RESIN: 105 Epoxy Resin is the base material on which all WEST SYSTEM 105 System epoxy compounds are built. The resin is a clear, pale yellow, low-viscosity liquid epoxy resin that cures to a hard, solid plastic with superior physical properties.
