## 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.

Use 300 Mini Pumps for convenient and accurate metering. 2. Mix with one of four WEST SYSTEM hardeners. Select a hardener for its intended use and for the cure speed best suited for your job in the temperature range in which you are working. 3. Add one of six WEST SYSTEM fillers to thicken the mixture as needed. Select a filler for its handling characteristics or cured physical properties. Or, add WEST SYSTEM additives to provide specific coating properties. WEST SYSTEM pigments can be used to change the epoxy's color.

Review: Perfect for our rental skis - This has become the only thing we use on our rental skis. It's worth it!
Review: Works as advertised - West system products worked very well. Easy to mix and apply with use of measuring hand pump, and syringe. Used to harden soft spots on RV floor. Make sure your holes are NOT drilled completely through the floor, or product will just run through. This product has a thin viscosity in order to inject where needed. Takes time to harden. Starts to harden within about 10-15 minutes. Oder is minimal which was a great surprise. Still used in well ventilated area.

## Questions & Answers

**Q: The description of this item says .43 Pints which is 7 ounces.  However, the picture of the container says 27.5 ounces.  Which is it?**
A: The WEST Systems products are sold in several sizes. 7 oz round cans, 32 oz rectangular cans as shown here, and large rectangular cans of 126 oz.   Try to confirm the size you are buying.

**Q: Shelf life of 205 hardener? My cured epoxy (105+205) is soft, gooey, even when measured exactly with a syringe.**
A: I believe 105 resin takes a higher proportion of hardener than 205 resin. Check the directions.

**Q: How much faster than the "slow" hardener does the "fast" one cure?**
A: On the manufacturer's website states cure time is 6 to 8 hours. The pot life at 72 degrees Celsius has 6 to 12 minutes to work with.

**Q: Will the pumps work on the smaller 7 fl oz cans ?**
A: I believe that if you purchase the set of 3 pumps, the smallest will fit the smallest container which is, I think, a pint. If you don't routinely use something like an eighth cup or more, you might want to consider buying some syringes from a farm supply store (a 60ml syringe for the resin and a 12 ml for the hardener). I recommend these sixes because the epoxy is mixed at a 5:1 ratio of resin to hardener and syringes of these sizes mix one major increment of one to one major increment of the other. Contact me again if this isn't clear.

### ⭐⭐⭐⭐⭐ Perfect for our rental skis

### ⭐⭐⭐⭐⭐ Fast and convenient
*by S***. on April 28, 2021*

This was my first time using West System epoxy. I bought this along with the kit with the 204A hardener. The 205 hardener worked great with plenty of working time for some butcher block waterfall counter tops I was assembling. Thick enough to address some minor gaping issues yet thin enough to squeeze out properly for a great wood joint. I've use the hardware store epoxies or small bottle epoxies for many years and finally bit the bullet for West System. More expensive upfront but much cheaper overall. It is so much more convenient. The pumps are quick and so much more accurate for ensuring a proper cure. I highly recommend this product.
