Atlac® 590Z, a corrosion-resistant phenolic-epoxy-vinyl ester resin, offers excellent heat resistance as well as resistance to solvents, acids, chlorine, and other oxidizing media. This resin maintains a high strength retention rate at elevated temperatures.
Characteristic Properties
- High Mechanical Strength
- Suitable for high-temperature applications
- Resistance to corrosion by strong oxidizing media
Typical Applications
Atlac® 590Z is a styrene solution of a phenol-modified vinyl resin with moderate reactivity and moderate viscosity. Atlac® 590Z exhibits exceptional high-temperature stability and corrosion resistance against organic solvents, acids, and oxidizing media such as chlorine, and also provides a very high retention rate of strength at elevated temperatures.Atlac® 590Z is suitable for most manufacturing processes, particularly filament winding, centrifugal casting, hand lay-up, and spray-up processes. It can also be used to formulate glass flake coatings and putty.
Certifications and Approvals
Cured, unreinforced Atlac® 590Z resin is classified as Type 1310 under German DIN 16946/2, Group 5 under DIN 18820/1, and Group 8 under European EN 12131/2.

Processing Guidelines
- The surface of Atlac® 590Z resin is non-tacky when properly cured. To ensure that surfaces exposed to air remain non-tacky, suitable additives (such as liquid wax) can be added to the resin.The product’s final cured state can be achieved through a post-curing treatment at high temperatures (120–150°C) for several hours to optimize its physical and chemical properties.
- Post-curing is strongly recommended for Atlac® 590Z products intended for chemical resistance.We recommend using a cyclohexanone peroxide or CuH/cobalt liquid curing system. When applying at temperatures below 15°C, it is recommended to add 0.1–0.5% of a 10% DMA (dimethylaniline) styrene solution as needed to improve curing efficiency.
- Before use, Atlac® 590Z resin must be stored under suitable temperature and humidity conditions for a consistent period of time; when using the MEKP/Co curing system, the operating temperature should generally be above 15°C.
