Usage instructions:
1. The ALITA 7016 resin does not contain wax, promoters, or thixotropic agents.
2. For the curing system in the extrusion process, it is recommended to use BPO curing agent at a concentration of 0.5-2.0% and TBPB curing agent at a concentration of 0.5-1.5%. The actual selection should be based on specific equipment, products, process temperature, extrusion speed, and other factors. To reduce shrinkage when producing thick-walled products, it is advisable to add low-shrinkage additives.
3. For applications requiring higher heat resistance and resistance to seawater, it is recommended to choose ALITA 239 resin, which is a benzene-based resin. For applications requiring higher anti-corrosion performance, it is recommended to choose ALITA 901 resin, which is an epoxy vinyl-based 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.
We provide small samples free of charge, but you will need to cover the shipping costs.
We have our own technical department. After you test the sample, please provide us with your detailed requirements. We can adjust the resin accordingly to enhance the properties of your finished products.
Honestly, it depends on the quantity. We will do our best to create a production plan based on your estimated time of arrival (ETA).
For the first trial order, we require 100% payment upfront. For subsequent orders, we ask for 30% payment in advance and 70% payment after the buyer receives the B/L copy. We also accept L/C if needed.
