Product Description

Atlac® 430 ACT is a pre-accelerated, thixotropic, high-grade bisphenol A epoxy vinyl ester resin formulated specifically for hand lay-up and spray processing. Its standout property is excellent antiosmosis resistance combined with long-term heat resistance, making it especially well suited to marine hull construction below the waterline and to tooling manufacture — two applications where blister-free, long-term water immersion performance is critical.

Compared with our general-purpose Atlac® 430, which is suited to filament winding, centrifugal casting, hand lay-up, and spray-up across chemical processing and marine applications, Atlac® 430 ACT is purpose-built for hand lay-up and spray processes only, with antiosmosis performance as its defining advantage for marine and tooling applications.If your process is vacuum infusion (VIP) or RTM instead, see the low-viscosity Atlac® 430 LV GT250.If flame retardancy is the priority, see the brominated Atlac® 430YT 901.

Benefits

● Good chemical resistance and good hydrolysis resistance

● Outstanding mechanical properties

● Heat resistance

● Good resistance to dynamic load carrying

● CCS/LR certification for boat building

Chemical/Physical Nature

Atlac® 430 ACT is a pre-accelerated, thixotropic, high-grade bisphenol A vinyl ester resin.

Liquid Resin Typical Properties

Application

Atlac® 430 ACT is especially adapted to meet the requirements of chemical resistance and outstanding mechanical properties, in applications such as tanks, vessels and devices, chemical resistance protection, water conservancy projects, pipe repair, anticorrosive flooring, and tool making. FRP made from Atlac® 430 ACT offers good heat resistance and dynamic load carrying capacity, and is suitable for hand lay-up and spray-up applications. The resin is recommended for the fabrication of chemical-resistant equipment, tooling, and marine applications.

Atlac® 430 ACT has been approved by China Classification Society (CCS) and Lloyd's Register of Shipping (LR) for boat building.
