## Description

This 105B Epoxy Resin is the base material on which all West System 105 System epoxy compounds are built. It is a clear, pale yellow, low-viscosity liquid epoxy resin. Blended with hardener at the proper ratio, it cures to a hard, solid plastic with superior physical properties. Based on which hardener you choose, it cures at a wide range of temperatures. Once cured, it forms a high-strength solid that is functionally waterproof, and highly resistant to moisture. The West System 105B Epoxy Resin is designed to wet out and bond with wood fiber, fiberglass, and reinforcing fabrics. It also bonds well with a variety of metals when mixed at the proper ratio with a West System Epoxy hardener.No Strong Solvent Odor105 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. Resin viscosity is approximately 1000 centipoise (cP) at 72-degree-F.Thickening EpoxyModifying this epoxy with West System fillers creates an excellent structural adhesive or fairing compound. You choose the filler that suits your project. Epoxy thickened with adhesive (high-density) fillers makes structural bonds, bridges gaps, and fills voids. Epoxy thickened with fairing (low-density) fillers is easily sanded and shaped after it cures.Bundle Includes:West System 105B Epoxy Resin (126.6 fl oz)West System 205B Fast Epoxy Hardener (27.5 fl oz)West System 300 Mini Pumps Epoxy Metering Pump Set (3-Pack)

## Features

- BUNDLE INCLUDES: West System 105B Epoxy Resin (126.6 fl oz), 205B Fast Epoxy Hardener (27.5 fl oz), and 300 Mini Pumps Epoxy Metering Pump Set (3-Pack)
- WEST SYSTEM EPOXY: Based on 105 Epoxy Resin, West System Epoxy is a versatile low-viscosity epoxy system. It is used for boat building, composite construction and repairs that require high-strength, waterproof coating, bonding, and filling. It readily wets out fabrics and porous materials, and is easily modified for a wide range of working conditions and applications
- NO STRONG SOLVENT ODOR: 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. Resin viscosity is approximately 1000 centipoise (cP) at 72-degree-F (22-degree-C)
- PRE-WARM THE RESIN AND HARDENER: Cold temperatures increase an epoxy’s viscosity, making it harder to dispense, mix and apply. Warming resin and hardener reduces their viscosity, so they flow easily through their dispensing pumps. To pre-warm, place the resin and hardener containers under a warming lamp or in a warm-water bath. Pre-warmed resins and hardeners will not cling as much to your mixing equipment
- FIVE-PART RESIN TO ONE-PART HARDENER RATIO: Mix 205 Fast Epoxy Hardener with 105 Epoxy Resin in a five-part resin to one-part hardener ratio. The resulting cured epoxy is a rigid, high-strength, moisture-resistant solid. The combination of 105 Resin/205 Fast Hardener has excellent bonding and coating properties. The West System 205 Fast Hardener is formulated to cure well at temperatures as low as 40-degree-F

## Questions & Answers

**Q: Can you recommend pigment for woodworking?**
A: I haven’t tried any pigments but I do use saw dust mixed in with it occasionally

**Q: About how many square ft. (plywood) would this product cover?**
A: I can't tell you about plywood because I used it on red cedar and cherry wood. I covered 120 Sq. feet over fiberglass over cedar which is very absorbent. I used one can and got three coats  of coverage. You should get more because plywood isn't as absorbent. Great product, has long shelf life! Hope this helps  Good Luck. Capt. George

**Q: How thick is the solution just after it has been mixed?  Is it similar to thick syrup or runny like water?**
A: The mixed epoxy is syrup like.  It Wil tend to sag & or run on a vertical surface if applied to thickly.  I tried brushing, rolling and spraying for the final few layers of exoxy

**Q: can you use this for molds, crafts?**
A: You can but it’s not crystal clear. It builds up in my mixing cup over time and has a yellow color to it when thick like that.
