Instruction and attention:

ALITA 8685 resin contains wax and does not contain accelerators or thixotropic agents.
Cutting and polishing should be performed after thorough curing during the production process.
Post-cure at a temperature of 60-70°C for a minimum of 3 hours for optimal product performance.
Moisture absorption by fillers should be avoided as high water content can affect product curing, resulting in decreased performance.

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.
