Product Description
Atlac® 580 ACT is a high-grade Bisphenol A urethane vinylester, dissolved in styrene. The resin is pre-accelerated and thixotropic, with medium viscosity and medium reactivity.
Atlac® 580 ACT is the hand lay-up- and spray-up-specific grade in the Atlac® 580 family. For other fabrication methods — filament winding, centrifugal casting, pultrusion, or resin injection molding — see general-purpose Atlac® 580.
Principal Properties
Atlac® 580 ACT has excellent wet-out and de-aerating properties for easy processing. Compared with conventional vinylester resins, foaming after MEK peroxide addition is highly reduced, leading to less air inhibition inside the laminate and on the surface. Due to its urethane incorporation, Atlac® 580 ACT features enhanced thixotropic behavior that prevents rinse-off on inclined mold surfaces, and shows improved compatibility with aramid fiber reinforcements.
The resin provides a low exothermic reaction during cure, allowing thick sections to be fabricated in one go, while thin laminates benefit from its excellent through-cure behavior. Final products made with Atlac® 580 ACT show excellent hydrolysis resistance and good thermal stability, and resist many aqueous media, acidic salts, alkaline media, and hot water. The resin offers an outstanding combination of heat resistance and flexibility.

Application
Atlac® 580 ACT is specially developed to meet the requirements of hand lay-up and spray-up applications. The resin is recommended for the fabrication of chemical resistant equipment and marine applications.
Atlac® 580 ACT has excellent wet out and de-aerating properties for easy processing. Compared to conventional Vinylester resins foaming after MEK peroxide addition is highly reduced in Atlac® 580 ACT leading to less air inhibition inside the laminate and on the surface. Due to its urethane incorporation, Atlac® 580 ACT features enhanced thixotropic behavior preventing rinse off inclined mold surfaces and shows an improved compatibility with aramid fiber reinforcements. Atlac® 580 ACT provides low exothermic reaction during cure allowing thick sections to be fabricated in one go, however through cure in thin laminates is favored by excellent curing behavior. Final products made with Atlac® 580 ACT show excellent hydrolysis resistance and good thermal stability. Atlac® 580 ACT is resistant to many aqueous media, acidic salts, alkaline media and hot water. The resin offers an outstanding combination of heat resistance and flexibility.
