Atlac 590Z is a novolac epoxy vinyl ester resin engineered for corrosive service environments, offering excellent thermal and chemical resistance against solvents, acids and oxidizing media such as chlorine. For FRP fabricators building chemical processing equipment, tanks, pipes and ducting that must hold strength at elevated temperatures, Atlac 590Z provides high mechanical strength, resistance to strong oxidizing medium corrosion, and reliable retention of properties under sustained heat.
What Is Atlac 590Z?
Atlac 590Z is a styrene solution of phenolic modified vinyl ester resin with moderate reactivity and viscosity. The resin offers excellent high-temperature stability and corrosion resistance to organic solvents, acids and oxidizing media such as chlorine, as well as high-temperature strength retention. It is suitable for most production processes, especially filament winding, centrifugal casting, hand lay-up and spray-up, and can also be used to prepare glass flake coating and cement paste.
Key Benefits of Atlac 590Z for Corrosive Service
- High mechanical strength suited to structural FRP components.
- Resists elevated temperatures without rapid loss of mechanical properties.
- Resistance to strong oxidizing medium corrosion, including chlorine exposure.
- Cured non-reinforced resin is classified as DIN 16946/2 type 1310, DIN 18820/1 group 5, and European EN12131/2 group 8.

Unfilled Castings and Fiberglass Reinforced Properties
Unfilled castings of this resin typically reach a tensile strength of 77 MPa, tensile modulus of 3.6 GPa, tensile elongation of 2.7%, flexural strength of 148 MPa, flexural modulus of 3.7 GPa, HDT of 144°C, Tg of 166°C, and unnotched impact strength of 13 kJ/m². With 34% glass fibre content, fiberglass-reinforced laminates report tensile strength of 110 MPa, tensile modulus of 10.1 GPa, flexural strength of 208 MPa, flexural modulus of 9.8 GPa, unnotched impact strength of 115 kJ/m², coefficient of linear expansion of 30×10⁻⁶ °C⁻¹, and heat conductivity of 0.19 W/m·k.
Curing and Processing Guidance
A typical curing schedule adds 1.0 g M50 (Nouryon) and 0.5 g NL-49P (Nouryon, 1% Co) to 100 g of resin, followed by 24 hours at room temperature and post-curing for 3 hours at 100°C and 1 hour at 150°C. The resin normally exhibits tack-free cure; where surfaces in contact with air do not become sticky, appropriate additives such as waxes can be added. For the best physical and chemical properties, the laminate can be post-cured through several hours at 120-150°C.
Post-curing is strongly recommended for ideal chemical corrosion resistance, and cyclohexanone peroxide or CuH/cobalt liquid curing systems are recommended. When processing below 15°C, a 0.1-0.5% 10% DMA (dimethylaniline) styrene solution should be added to improve curing efficiency, and before use the resin should be stored in a suitable temperature-humidity environment for a consistent period. When an MEKP/cobalt curing system is adopted, operating temperature should stay above 15°C.
Storage Guidelines
The resin should be stored in a dark and dry place at temperatures between 5°C and 30°C. Shelf life is reduced when stored at higher temperatures, and the properties of the resin might change during storage. Because this is a styrene-containing vinyl ester, shelf life will be significantly reduced when exposed to light; storage in dark, 100% light-tight containers only is recommended, and exposure to direct sunlight should be avoided.
