Chemical/Physical Properties
Atlac® E-Nova FW 2045 is a modified epoxy bisphenol A vinyl ester urethane resin dissolved in styrene.
major application
Atlac® E-Nova FW 2045 can be used in all fabrication methods, but is particularly suited to meet the requirements of fiber winding, centrifugal casting, hand laminating, and spraying applications.
Atlac® E-Nova FW 2045 provides the same excellent thermochemical resistance to solvents, acids and oxidizing media as epoxy phenolic vinyl esters, with the added benefit of alkali resistance.
E-Nova technology combines the processing ease of polyester with the chemical resistance of vinyl ester. Low foam curing is possible with standard MEKP peroxides, and it exhibits excellent fiber infiltration compared to conventional vinyl ester resins.Atlac® E-Nova FW 2045 can be easily prepared as a rheology agent.
accreditation
The cured, unreinforced Atlac® E-Nova FW 2045 conforms to DIN 16946/2, type 1310, is classified as type 5 according to DIN 18820/1 and type 7B according to EN 12131/2. Atlac® E-Nova FW 2045 has received the general approval of the German Institute of Building Technology (DIBt) for parts for the storage of chemicals.

All test samples were cured at 100°C for 3 hours and then at 150°C for 3 hours. The laminates were based on 450 g/m² chopped short-cut fiberglass cloth in 4 layers.
Pre-use Guide
Prior to use, the resin should be adjusted to a specific temperature (usually 15°C minimum for MEKP/Co hardeners) according to the specific application conditions. Stir the product before mixing.
