## 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. 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. Versatile WEST SYSTEM Epoxy meet the highest standards for reliability, consistency, and product support. 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.

Review: Perfect for laminating composites - I primarily do wood working but have recently started wrapping some of the pieces of my projects in carbon fiber. I reached out to West directly to find out which product is best for what I am doing. 207 was it (combined with 105 resin). It mixes very easily, goes on smooth, flows well, and permeates the fabric without any issue at all. I was a little surprised at the pot time since it's far longer than i am used to. But that makes it even better when doing things like laminating composites since it gives you more time for adjustments. I really like it and I will continue using it for the foreseeable future.
Review: Great clear epoxy for wood outside - You mix this with 105 resin, apply it to wood ( I suggest two or three coats) that will be up against the weather, and it will give a good protective coat that should last for years. For UV protection, put on two coats of spar varnish. I suggest Captain's Flagship. West System has quality products and excellent customer support. I am currently using it for mahogany garage door skins.

## Questions & Answers

**Q: Can this product be brushed on a vertical surface?**
A: The WEST SYSTEM 105 with 207 hardener can be challenging to brush on without getting sags or runs.  The best practice is to use a thin foam roller cover like our 800-2 to roll on a thin even coat and follow with a brush to smooth out the roller marks.

**Q: For filling voids, what's the maximum depth per pour?**
A: Not deep. It will overheat and bubble and crack. Unless void is thin. I've filled 2 inch deep voids but they were less than 3/16 thick. I've had overheating in as small as half inch by roughly 2 square inches.

**Q: Is this product ok to repair surfboards with?**
A: Not sure. I am using it for a cedar strip canoe. Perhaps check the west system web site or talk to their technical team

**Q: Is it 3 pumps : 1 ?**
A: The pump system is sold as a set...

### ⭐⭐⭐⭐⭐ Fantasitc epoxy coating for finishing wood and bar tops...
*by A***D on February 11, 2013*

I am impressed with it. I tried a few sample pieces of wood before using it on a real project so that I could get a good feel for working with it. This stuff is very clear and does not yellow in a short period of time. However, it is not UV resistant. Make sure you mix it with the 105 resin at an ambient air temperature of about 70+ degrees Fahrenheit to help prevent air bubbles from forming. It is OK if a few bubbles form since you can use a heat gun or torch to pull them out after you poor it on the surface. Heat gun is preferable. While it may be hard after 24 hours of applying it, it actually does not become fully hard until about 7 days later. It levels out very well. The final thickness ends up being about 1/16 to 3/32 of an inch. However, you can also spread it to a very thin layer with a squeegee if you want to use it as a base/sealer coat for finishing furniture. It fills in the wood grain pours nicely. I found it to work even better if you rub on a thin coat of polyurethane prior to applying the epoxy. This helps to prevent air bubbles from forming due to tiny air pockets in the wood. It does easily soak into end grain; so about two coats of polyurethane will be needed on the end grain to slow the absorption rate. The pumps they offer ( Mini Pump Kit for 301 and 305 in Quart, Gallon, 5 Gallon sizes ) are a great help to meter out the correct quantity of chemicals. However, the pumps do not necessarily work correctly at each pump action. Some of the pumping action will suck in air on the up stroke and prevent the pump from correctly metering the next output on the down stroke. Therefore, be attentive when using the pumps. The West System 207 hardener and 105 resin mix at a ratio of 3:1 For most projects, I used this kind of mixing cup ( 1/2 Pint Disposable Mixing Cups 100/Box ) since smaller cups can be too small, and I don't need large cups very often. This 207 hardener will not sick to these cups when fully hardened in them. Customer service at West System is excellent. I got a live person who referred me to a very knowledgeable representative in their office.
