Principal Properties & Application:
ALITA 197 resin is an epoxy-modified unsaturated polyester resin of the bisphenol A type, primarily composed of D-33 monomers and epoxy resins. It has a medium viscosity and high reactivity. ALITA 197 resin falls under the chemically resistant CEE category and demonstrates exceptional corrosion resistance, particularly notable alkali resistance, high mechanical properties, and a high heat distortion temperature. It is suitable for the production of chemical equipment such as fiberglass-reinforced plastic (FRP) pipes, containers, and storage tanks that require moderate heat resistance and chemical resistance.

Note:
1. The casting process follows GB/T 8237-2005, with a curing system consisting of 0.5% Co/oct promoter and 2.0% Butanox M-50 curing agent.
2. After casting, the curing treatment involves 24 hours at room temperature, followed by 2 hours at 60°C and 2 hours at 80°C.
3. After applying fiberglass reinforcement, the curing treatment involves 24 hours at room temperature, followed by 3 hours at 60°C and 3 hours at 110°C.
Instruction and attention:
1. ALITA 197 resin does not contain wax and does not contain promoters or thixotropic agents.
2. For applications requiring higher heat and corrosion resistance, it is recommended to select ALITA epoxy-based 901 resin.
3. When choosing a resin with heat and chemical resistance, it is necessary to refer to our company's "Heat and Chemical Resistance Medium Usage Query Table" based on the actual usage medium and temperature of the product, and select the suitable resin accordingly, which should be confirmed through testing.
4. Proper curing of corrosion-resistant FRP products is especially important, and the products should only be used after they have fully cured.
Handling and Storage:
This resin contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary protective equipment and clothing should be worn.
Drums - It is highly recommended that all material is stored at stable temperatures below 25°C (77°F). Avoid exposure to heat sources such as direct sunlight or steam pipes. To avoid contamination of product with water, do not store outdoors. Keep sealed to prevent moisture pick-up and monomer loss. Rotate stock.
