Corrosion-Resistant Vinyl Ester Resin
Products made from Atlac® 430 resin feature high mechanical properties and exhibit excellent corrosion resistance and heat resistance. Whether combined with carbon fiber or glass fiber,
Atlac® 430 resin yields high-strength, durable components.
Key Properties
- Continuous Operation Applications
- High-Temperature Applications
- Design Flexibility
- A Cost-Effective Option for Owners
- Suitable for Carbon Fiber and Glass Fiber
Typical Applications
Atlac® 430 resin is suitable for all manufacturing methods but is particularly well-suited for applications involving filament winding, centrifugal casting, hand lay-up, and spray-up processes. Atlac® 430 has moderate reactivity and moderate viscosity.
Composites based on Atlac® 430 resin are resistant to various acids, alkalis, and bleaching agents in corrosive chemical industrial environments. The perfect combination of heat resistance and high elongation makes the resin suitable for thermal shock caused by sudden temperature fluctuations.
Certifications and Approvals
The properties of cured Atlac® 430 resin castings comply with Type 1310 of German Standard DIN 16946/2 and Group 5 of German Standard DIN 18820/1.Atlac® 430 complies with Group 7A of the European standard EN 13121/1.
Depending on customer requirements, Atlac® 430LSE resin products—manufactured from appropriately screened raw materials and properly cured—can comply with FDA Title 21 CFR 177.2420 for reusable food contact equipment.
Atlac® 430 resin has obtained a WARAS certificate confirming compliance with the British Standard “BS 6920: 2000—Suitability of Non-metallic Products for Use in Contact with Water Intended for Human Consumption.”
Atlac® 430 resin complies with all requirements of the Chinese National Food Safety Standards “GB 4806.6-2016 Plastic Resins for Food Contact” and “GB 9685-2016 Standards for the Use of Additives in Food Contact Materials and Articles.”
This resin has been certified by Lloyd’s Register and the China Classification Society and is suitable for use as a gelcoat matrix resin and a resin for laminate manufacturing in boat construction.
