ALITA 262 Unsaturated Polyester Resin - Low Viscosity & Medium Reactivity

Principal Properties & Application:

ALITA 262 resin is an unsaturated polyester resin based on phthalic anhydride as the main raw material. It has low viscosity and medium reactivity. ALITA 262 resin has good rigidity and is not easily deformed, making it suitable for the extrusion and drawing of products such as fishing rods, tent poles, and grilles.

Note:
The casting method is performed according to GB/T 8237-2005, curing system: promoter 0.6% Co Naph 1.0%, curing agent Enox BPO-50F 1%;
Casting: 4mm thick, post-curing conditions are: room temperature × 24h, 60℃ × 3h, 110℃ × 2h.

Usage instructions:

1. ALITA 262 resin does not contain wax, accelerators or thixotropic agents.
2. The recommended curing system for extrusion process is: BPO curing agent 0.5-2.0%; TBPB curing agent 0.5-1.5%. The actual selection should be based on specific equipment, products, process temperature, extrusion speed and other factors. When extruding thick products to reduce shrinkage, it is recommended to add a low shrinkage agent.
3. For higher heat resistance and seawater resistance requirements, it is recommended to choose m-phenylene type ALITA 239 resin; for higher corrosion resistance requirements, it is recommended to choose epoxy vinyl type ALITA 901 resin.

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.
