Marine Epoxy is but one application for this super adhesive
I simply never fail to be amazed by the applications and industries that use epoxy. Marine epoxy is just another purpose to which one can add to the ever-long list of epoxy adhesive uses.
Once again the natural characteristics (being waterproof) and the ability to manipulate the formula to suit the application, epoxy is a front-runner for marine construction and repair. Marine grade plywood is saturated with epoxy making it impervious to water. It is used as an adhesive in stitch and glue boat construction. As an adhesive coating, marine grade epoxy is used to apply fiberglass tape and cloth. Marine epoxy filler is used as a gap filler and fairing compound. While there are a few options when it comes to boat repair, marine epoxy resin seems to be the most favored compound to use.
In addition to its aquatic uses, clear marine epoxy has become multipurpose and is commonly used in pebble paving and floor coatings. For epoxy, this is no surprise; it often is developed for one application but because of its unique features is employed for a totally different purpose.
The best marine epoxy consists of two parts: the resin and a hardener, or catalyst, that’s always mixed with the resin to cause it to cure. Many waterproof epoxies will cure underwater as well. The ratio of resin to hardener varies among brands of epoxy. It is imperative when using any epoxy, not just marine epoxy glue, that you follow the manufacturer’s instructions. Epoxy that has too much, or too little, hardener will not achieve full strength when cured.
As epoxy cures it generates heat, which accelerates the cure time. If a large mass of epoxy is left to cure in a container, such as a mixing cup, it will harden very rapidly, often in a matter of minutes. However, if that same quantity is spread out, say on a boat’s hull, the curing time could be hours. This is so because of the large surface area allowing the heat to dissipate, slowing the drying time.
Generally speaking the minimum temperature for working with most epoxies is around 60 degrees. However, using “slow” hardeners with temperatures over 70 degrees allow for quicker cure times, less than 24 hours. Adhesive manufacturers have also developed epoxies with “fast” hardeners for even shorter curing times or for use in cooler temperatures.
Suppose your boat needs a quick repair at the dock or the beach, most marine epoxy can cure underwater. Marine epoxy fills can be performed for damage that cannot be otherwise addressed. However, until the marine epoxy filler is cured the force of the water can distort the soft epoxy if the boat is in use.
Epoxy resins, hardeners, and solvents contain potentially dangerous chemicals. Avoid getting them on your skin by wearing disposable gloves. Acetone is typically used to clean tools and spills. If you do happen to get it on your skin use soap and water, vinegar, or mechanic’s waterless hand cleaner. Epoxy is relatively odorless, but does expel gasses that with repeated exposure can cause sensitivity. When sanding cured epoxy it is absolutely necessary to wear a respirator.
Marine epoxy is just one of many developments made by . I feel quite confident that with research and beta testing, epoxies of the future will truly be something to marvel.
