Marine environments are among the most demanding for any material — constant exposure to saltwater, UV radiation, mechanical stress, and biofouling places extreme requirements on both the resin system and the reinforcement used in boat building and offshore structures. Amtech's isophthalic and marine-grade UPR formulations are specifically engineered to address these challenges, offering superior hydrolytic stability, low water absorption, and long-term resistance to osmotic blistering.

Our woven roving and CSM reinforcements, when used in conjunction with these marine-grade resins, enable fabricators to build hulls and structural components that maintain their mechanical integrity over years of continuous service in water. Whether it is a small fishing boat operating in coastal waters or a larger recreational vessel built for open-sea conditions, our product systems provide the strength-to-weight ratio and durability that marine builders depend on.

Beyond hull construction, our silicone sealants, flowcoats, and surface mats support finishing and sealing operations on deck fittings, hatches, and below-waterline surfaces — giving boat builders a comprehensive material solution from a single supplier.
