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.
