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.
