Storage: Moisture will have a negative impact on the curing process and final strength, and the main agent and curing agent must be protected from moisture. The recommended storage temperature is 10-30°C.Avoid direct sunlight, high temperature and frost. Under the specified conditions, the storage period in the original sealed container is 6 months.
Instructions: Before using this product, make sure that the surface of the substrate to be bonded is clean, dry, free of dust and any grease. Mix the main agent and curing agent according to the proportion and stir evenly. Glue can be applied by serrated scraper, roller, two-component machine. During the curing process, it is necessary to make the contact surface have a certain pressure, so as to ensure that the glue is in close contact with the two layers. Contact Supex Technical Service for more information.
Cleaning: Uncured glue can be removed by Supex cleaner, cured adhesive needs to be removed by mechanical scrapping.
