Marine Epoxy

Epoxy Resin for Boats

Because of its product properties epoxy resin is well suited for boats. Marine epoxy can be used for building new boats, as well as for modifications and repairs. EPODEX’s marine epoxy is solvent-free and ultra-resistant so that you can count on it even in troubled waters. Bring your ship on course and start a project with our professional resin kits.

Advantages of Marine Epoxy

Boats are often made of polyurethane resin, which is durable only after preliminary treatment with bonding agents. Furthermore, it evaporates stronger than epoxy resin. Marine epoxy is an easy-to-use, up-to-date material for building or repairing boat hulls.

It offers excellent impregnation, is ideally suited for laminating and extremely durable and resistant. Marine epoxy is characterised by low material shrinkage, effective osmotic protection and excellent adhesion. Therefore, it is not surprising that epoxy resin is used in aviation, wind power plants and the automotive industry, too. Hardly any other material combines easy processing with such good adhesion and durability.

Epoxy Resin in Boat Building

EPODEX offers 4 different resin kits for a wide range of applications. In boat building, we mainly recommend our epoxy primer, EPODEX Sealer & Primer, and the coating resin EPODEX ECO.

Unlike any other epoxy primer, the water-based EPODEX Sealer & Primer can be applied with a foam roller and is not self-levelling. It ensures strong adhesion, even under tricky conditions, and is slip-resistant and durable. It can be used to seal walls and floors and is an ideal base for further layers of casting resin. It is also well suited as the sole floor sealant on your boat.

EPODEX ECO is a low-viscosity epoxy resin for the impregnation of layers of glass fibre, carbon fibre, aramid or mixed fibre fabrics. This creates a fibre composite with which you can laminate boats in the best possible way.

ECO System (Resin+Hardener)

Repair Your GRP Boat with Epoxy Resin

Does your boat made of GRP have holes, osmosis or other damages? Then you best refit it with epoxy resin! You can use epoxy putty to fill small holes and damaged areas, but with our resin you can also repair larger damages. Our Sealer & Primer System provides a new, step-resistant floor on your boat. With 2-part epoxy glue you can create extremely strong bonds, which can be drilled, painted or sanded after curing.

Marine epoxy is essential to boat building, because no other material is better suited and more optimally adapted to the requirements of GRP boats. Since GRP is a glass fibre reinforced plastic (a material made of plastic and glass fibres), repairing your boat works best with marine epoxy. Use EPODEX ECO to impregnate glass fibres and repair your GRP boat. It does not play a role, if a different material was originally used for your boat, epoxy resin allows long-lasting bonds.

How to Use Marine Epoxy

On rough seas, your boat is exposed to various stresses like salt water, temperature fluctuations, mechanical stress and high humidity. Marine epoxy offers the highest possible protection against those stresses. During processing and curing time there are several things to consider. The ambient temperature should constantly be around 20°C when applying epoxy resin. While lower temperatures slow down the chemical reaction of resin and hardener, higher temperatures accelerate the process. As a rule of thumb, an increase of 10°C doubles or triples the chemical reaction rate.

It is also very important that humidity does not exceed 70%, otherwise finish and look of the surface will be negatively affected. Our water-based primer system EPODEX Sealer & Primer System is the exception to that rule, as it was specially designed for humid surroundings. If you already have laminated or coated your boat or parts of it, you can subject our resin kits ECO, PRO or PRO+) to a subsequent heat treatment. This process, which is called tempering or post-curing, significantly improves durability and heat resistance.
