Principal Properties & Application:
ALITA 6688 resin is an unsaturated polyester resin primarily made from phthalic anhydride. It has high viscosity and moderate reactivity. ALITA 6688 resin has a light color, good flexibility, strong adhesion, and provides a glossy and full coating, making it suitable for surface coatings on stone and furniture.

Instruction and attention:
- ALITA 6688 resin contains wax but does not contain accelerators and thixotropic agents.
- Recommended curing system: special colorless accelerator 0.4-2.0%, MEKP curing agent 1-2%. In actual operation, the dosage of curing agent and accelerator should be determined through on-site trials based on environmental conditions such as temperature and humidity.
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.
