Product Properties
Atlac 430ACT is a styrene solution of a pre-accelerated thixotropic epoxy bisphenol A vinyl ester resin with moderate reactivity and moderate viscosity.
Main Applications
Atlac 430ACT can be used in glass-fiber-reinforced components requiring excellent chemical resistance to achieve superior mechanical properties, such as storage tanks, containers, and
equipment; corrosion protection; hydraulic engineering; sewer pipe rehabilitation; and corrosion-resistant flooring.Laminates manufactured with Atlac 430ACT exhibit excellent
long-term heat resistance and high dynamic load-bearing capacity.
Atlac 430ACT is suitable for various processes, including hand lay-up, spray-up, filament winding, and centrifugal casting.
