Additional Info:

Choosing the Right Epoxy System
WEST SYSTEM® 105 Epoxy Resin® is a professional quality, two-part epoxy system developed for high strength and good versatility. The Epoxy Selection Guide is a handy tool to help you pair 105 Epoxy Resin with a choice of four hardeners to best match your working temperatures, desired cure speed, and coating clarity.
Epoxy System Selection Guide

Estimating Coverage for Fabric Application
Estimating how much epoxy is required to wet out fabric is based on the fabric weight and square footage. We provide estimates of the amount of epoxy needed to apply 1 sq. ft. of fiberglass cloth.

Coating
This epoxy is also a great coating material. Applied with a roller, it offers excellent thin-film characteristics. It will flow out and self-level without “fisheyeing.” 105 Epoxy Resin’s viscosity is approximately 1000 centipoise (cp) at 72 F (22C).

Filler and Epoxy Strength
WEST SYSTEM Epoxy fillers are used to thicken the basic epoxy resin/hardener mixture for specific applications. Adding these filling agents to blended epoxy resin and hardener allows you to control the consistency of the epoxy, bridge gaps in joints, create either strong or sandable fillets with epoxy, or alter the cured density of epoxy, making it easier to sand smooth.

Additives and Pigments
Additives and Pigments provide additional properties such as abrasion resistance and coloration. Reinforcing materials such as fiberglass cloth and carbon tapes should be selected based on where and how you want to enhance structural reinforcement.

Epoxy Techniques
We believe every builder or repairer should develop an understanding of 105 Epoxy and a feel for working with it. We strongly recommend performing simple “shop floor” tests as you proceed. The 105 Epoxy System was designed to give you the flexibility to tailor the epoxy to meet your project's and work environment's demands. If you’re starting out, familiarize yourself with our recommended epoxy techniques. When you understand the working and cured characteristics of your 105 Epoxy blends, you’ll develop the best solutions to construction and repair problems.

Metering Pumps

For group sizes "A", "B" and "C", 205 and 206 Hardeners are mixed with 105 Epoxy Resin in a ratio of 5:1. 207 and 209 Hardeners are mixed with 105 Epoxy Resin in a ratio of 3:1. To make sure you get the proportions right, we highly recommend purchase of the 300 Mini-Pump Kit, which meters the hardener and resin in the exact proportions you need. For group size "E" and larger sizes, we suggest use of either the 306-23 Special Purpose Resin/Hardener pump (Model 128845), which dispenses hardener and 105 Epoxy Resin at a ratio of 3:1, or the 306-25 Special Purpose Resin/Hardener pump (Model 335703), which dispenses hardener and 105 Epoxy Resin at a ratio of 5:1.

Epoxy Safety is Important
Epoxy is a chemical product and should be handled with care. Whether you’re a new user of WEST SYSTEM Epoxy or an old hand at it, you’re always better off with the most up-to-date information on using epoxy safely. We strive to make it easy for our epoxy customers to find our Safety Data Sheets and learn the best practices for using epoxy safely.

Epoxy Shelf Life & Proper Storage
WEST SYSTEM resins and hardeners do not have a strict shelf life. Certain changes may make them less effective for some jobs, but the resin and hardener will still be reactive. Because we are an ISO 9001 company, lot numbers are provided on containers, and we keep retains of every batch we make for up to 2 years from the date of manufacturing. However, the actual shelf life is typically far longer.
