What's So Great About Epoxy?
Epoxy resin is one of the most valuable tools available for modern boat repair and construction. Epoxy adhesive's popularity is due in large part to its versatility--it can be used for making small repairs as well as cold-molding a brand new hull. The nature of the material allows you to create a mixture with the precise characteristics that you need.
The basic ingredient for all epoxy adhesive compounds is the epoxy resin. By using a simple cookbook approach and measuring carefully, you can tailor both the handling characteristics and the physical properties of the cured resin. To achieve the proper ratios (resin/hardener) we offer calibrated pumps to deliver the correct proportions. Fillers are designed to thicken the epoxy mixture. Use a High Density filler for strength and bulk. And use a Low Density filler for cosmetic or an easily sandable compound. Fiberglass cloth and other reinforcement materials are often used in conjunction with the epoxy to provide additional strength.
Mixing up a batch of Epoxy Adhesive / Fibreglass Resin:
- Wear gloves and a respirator. Dispense the proper proportions of resin and hardener into a clean plastic, metal or wax- free paper container. Don't use glass or foam containers because of the potential danger from exothermic heat build-up.
- Measure Carefully. Most problems related to curing of the epoxy can be traced to the wrong ratio of resin and hardener. To simplify measuring, we recommend using calibrated pumps to dispense the resin and hardener. All three major epoxy manufacturers, WEST System, System Three, and MAS all have pumps specially created for their mixtures, make sure you have the correct pumps and read the instructions.
- Stir the two ingredients together thoroughly-at least 1 minute-longer in cooler temperatures. To assure thorough mixing, scrape the sides and bottom of the pot as you mix. Use the flat end of the mixing stick to reach the inside corner of the pot. Curing epoxy generates heat. For this reason do not use foam or glass mixing containers.
- Fillers are added to thicken epoxy for specific applications such as bonding or fairing and sometimes just to fill and keep a batch from dripping. Select the appropriate filler for its handling characteristics and cured physical properties. Epoxy adhesives and fibreglass resins are much easier to work with than many think. It's all about the correct ratio and application.
