Atlac 580 is a vinyl ester urethane resin used for components and skin coats in marine applications, broadly specified for fiber reinforced parts fabricated through hand lay-up and spray-up processes. Skin coats based on Atlac 580 provide a combination of hydrolysis resistance, thermal stability, and ductility that buyers sourcing resin for classed vessels and corrosive-service equipment look for in a laminating system.
Atlac 580 Key Benefits
- Easy processing through excellent de-aeration and fiber wetting
- Excellent hydrolysis resistance
- Certified by Lloyd’s Register and Registro Navale Italiano (R.I.Na.)
- Unique combination of thermal resistance and ductility
Components made with this resin show good thermal stability and are resistant to many aqueous media, acidic salts, alkaline media, and hot water, offering an outstanding combination of heat resistance and flexibility. Atlac 580 has excellent wet out and de-aerating properties for easy processing, and compared to conventional vinyl ester resins, foaming with MEK peroxide is highly reduced, which lowers air inhibition both inside the laminate and at the surface.
Major Applications of Atlac 580
This resin is broadly used for skin coats in the manufacturing of boats and vessels through hand lay-up and spray-up processing. It features enhanced thixotropic behavior that helps prevent rinse off on inclined mold surfaces, and shows improved compatibility with aramid fiber reinforcements. Atlac 580 provides a low exothermic reaction during cure, allowing thick sections to be fabricated in one go, while through-cure in thin laminates is favored by its curing characteristics.
Certifications and Approvals
Cured non-reinforced Atlac 580 conforms to type 1310 according to DIN 16946/2, and according to EN13121/1 it is classified group 7B. It is certified by Lloyd’s Register and Registro Navale Italiano (R.I.Na.) as a laminating resin for use in marine applications, which is relevant documentation for fabricators supplying classed vessels.
Sourcing Atlac 580 for Boat Building and Equipment Fabrication
Composite manufacturers sourcing this resin for boat hulls, decks, or corrosive-service equipment benefit from consistent supply chain resource support alongside complementary materials such as glass fiber reinforcement and curing systems from the same resin category. Marine fabricators typically specify skin coats made with it against classification society standards such as those referenced by DNV rules and standards for craft construction, in addition to the Lloyd’s Register and RINA certifications already associated with this resin.
