Shipyards, for the most part, are manufacturing polyester fiberglass yachts. However, it is possible to use epoxy resins instead of polyester, as this increases their strength ten-fold, although the cost increases significantly.
Apart from the main boat, which is made of polyester, there are many sections where epoxy materials, such as epoxy putty, epoxy paint, epoxy resins, etc can be used.
Megapoxy has the right materials for shipyards.
Low viscosity epoxy resin hydrophilic
Solvent free hydrophilic epoxy extra low viscosity
High strength impact resistant epoxy adhesive
