Principal Properties & Application:
ALITA 901-1 is an epoxy vinyl ester resin designed for fast pultrusion. It has moderate viscosity and high reactivity, which can greatly increase the pultrusion line speed, improve the surface gloss of the product, reduce shrinkage, and reduce internal microphase cracks in the product. The pultruded products have both corrosion resistance, mechanical properties and electrical properties. The FRP core material obtained by pultrusion with ALITA 901-1 has high heat-resistant bending and strength. A core material circle with 50 times the diameter of the FRP core material can be unbroken for 24 hours at an ambient temperature of 100 ° C, which can reduce the defect rate of high-end core
materials to a minimum. It is especially suitable for fast pultrusion of optical cable reinforcement cores with diameters from 0.5 mm to 4 mm.

Note:
The casting body production method is performed according to GB/T 8237-2005, and the curing system is: 6% Co-Naph: 0.2%, AKZO LPT: 1.5%;
The post-curing system of the casting body is: room temperature (24h) +60C (3h) +100C (2h).
The recommended ratio (weight ratio) is:
| Season | Resin/ENOX BPO-50F/ENOX TBPB |
| Summer | 100/0.5～1.0/1.0～2.0 |
| Winter | 100/1.0～2.0/1.0～2.0 |
Note:
The extrusion solidifying agent mostly uses medium-high temperature composite solidifying agents, that is, BPO and TBPB are used together. In actual use, it needs to be adjusted according to different mold temperatures, extrusion speeds, product thickness diameters, and seasonal temperatures.
Benzoyl peroxide ENOX BPO-50F is a medium-temperature peroxide curing agent product from ENOX; tert-butyl perbenzoate ENOX TBPB is a high- temperature peroxide curing agent product from ENOX.
Handling and Storage:
This resin contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be a voided and necessary protective equipment and clothing should be worn.
Drums - It is highly recommended that all material is stored at stable temperatures below 25℃ (77℉). Avoid exposure to heat sources such as dir ect 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.
