ALITA 262 – Orthophthalic Pultrusion Resin

Principal Properties & Application:

ALITA 262 resin is an unsaturated polyester resin based on Orthophthalic acid as the primary raw material. Featuring low viscosity and medium reactivity, ALITA 262 resin offers exceptional rigidity and minimal deformation, making it ideal for the pultrusion process. This resin is perfect for producing pultruded fiberglass products, with a particular emphasis on pultruded grilles, as well as fishing rods and tent poles, through continuous pultrusion. Its superior properties ensure high-performance pultruded composites suitable for various demanding applications.

Liquid resin technical indicators:

Note: Gel time test at 25°C: 25°C water bath, add 0.9g accelerator (1% Co) and 0.9g M-50 (Nouryon) to 50g resin.

Physical properties of the casting (for reference only):

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.
