ProMarine Announces 521 Marine Epoxy Resin Back in Production

Marine Epoxy Back on Market – New Production Facility Up-and-Running

November 19, 2019 (Galesburg, MI) – ProMarine Supplies, a leading supplier of high-performance epoxy resins for residential, commercial and industrial applications, is pleased to announce the relaunch of their 521 Marine Grade Epoxy Resin. The new manufacturing facility in Michigan is up-and-running – producing their market-leading polymer that features interchangeability with 521 Fast or Slow Hardeners – for a wide variety of marine applications. 

Versatile epoxy resin is a valuable tool in the marine industry as it can be used for a variety of applications; for everything from small repairs, to molding brand new hulls and decks. Unlike its predecessor, polyester resin, epoxy resin provides a much better material for today’s lighter weight, thinner and more flexible hulls.

In his piece, ‘Polyester or Epoxy Resin,’ boat care expert Don Casey explains, “Polyester is an adequate adhesive but not as good as epoxy. As a general rule, the tensile strength of a polyester bond will be around 20 percent weaker than the same bond made with epoxy. That makes epoxy resin usually the best choice for fiberglass repair work.”

Epoxy resins differ from other adhesives in other important ways as well. For instance, they feature hardeners of different speeds – an important quality for marine use. In warmer conditions, a slow hardener may be employed, giving a longer ‘working time’ to handle and shape the material. Conversely, a fast hardener resin may be applied in colder temperatures when a repair needs to be cured quickly.

Pro Marine’s 521 Marine Epoxy Resin cures to a moisture-resistant solid perfect for laminating, bonding, coating and reinforcing for use in myriad marine applications. Easy to measure, apply, sand and paint – the polymer is available in quart and gallon kits complete with resin, hardener and pumps – and features: 

  • Superior Bonding – with fiberglass, wood, etched aluminum, fabrics, bare steel & lead
  • Self-leveling Properties – ideal for coating & laminating
  • Preferred Viscosity – for ‘wetting out’ fiberglass and other fabrics
  • Compatibility – with fast (12 min) or slow (30 min) hardeners

“We very pleased to have our new production line up-and-running,” enthused Jennifer Bonwill, General Manager, ProMarine Supplies. “Our state-of-the-art production and order processing facility enhances our ability to best address our growing customer base. We look forward to continuing to serve our current customers, and customers to be, for their marine epoxy needs!”
