typical application
Atlac? 590UHT resin is the material of choice for composites at high service or design temperatures. The resin is designed to facilitate the production of composite products by hand lay-up, injection molding, fiber winding, compression molding and resin transfer molding RTM processes.
Atlac? 590UHT resin has been used in the manufacture of chemical storage tanks and piping, flue gas desulfurization (FGD) system equipment, chimneys, scrubber towers, and flues.
Atlac? 590UHT resin exhibits excellent resistance to organic solvents due to its high crosslink density.

The curing system is: 1.0 g of curing agent Butanox M50 with 1.0 g of accelerator NL 49P in 100 g of resin. Cure at room temperature for 24 hours and post cure at 130°C for 3 hours.
The curing system described above was cured at room temperature for 24 hours and post cured at 130°C for 3 hours and then post cured at 200°C for 24 hours.
Process Operation Guide
- Maintain a hardener dosage level of between 1.01 TP6T and 2.01 TP6T of total resin weight to obtain fully cured strength;
- The temperature of the workshop should be maintained between 18℃ and 32℃, and the humidity of the workshop should be maintained between 40% and 90%. Constant shop conditions will result in constant gel time and help the manufacturer produce high quality products.
- Considering that Atlac ? 590UHT is a highly reactive resin, isopropyl peroxide CuHP is the recommended curing agent. The surfaces of manufactured products cured at room temperature in contact with air should be relatively non-sticky. However, they may not be fully cured and therefore have less resistance to chemicals than fully cured products. If further layers are not intended, a styrene solution of 10% containing 5% paraffin (melting point: 46-48°C) can be added to the final layer of resin to obtain a non-tacky surface.
- The use of an isopropylbenzene peroxide catalyst is recommended because of the fast cure of Atlac ? 590UHT resin. If the composite part is very thin, highly dimerized methyl ethyl ketone peroxide can be used.
- Atlac ? 590UHT composites already cured at room temperature are then cured at 70-100°C for two hours for optimum cure and performance.
Application Operation Guide
Due to the excellent curing characteristics of Atlac? 590UHT resin, all secondary bonding is done as soon as possible. Exposing the laminated composite to sunlight can cause serious secondary bonding problems. After 48 hours of curing, the laminated composite needs to be sanded with 16-24 grit (14-20 grit) coarse sandpaper to ensure good
Good secondary bonding, especially if the laminated composite surface is rich in resin. Avoid low glass fiber content and resin build-up.
