Two-component polyurethane adhesive is widely used for sandwich panel bonding because of its high strength and durability.
Yes, PU adhesive is commonly used in cold room panels because it offers strong bonding and temperature resistance.
Curing time depends on temperature and humidity but typically ranges from several hours to full curing within 24 hours.
It bonds:
Two-component PU adhesive is considered one of the best adhesives for insulated sandwich panels due to its strength and durability.
It is used for bonding of pretreated metals, synthetic materials, wood and hard foams. Main application is the
production of sandwich elements, e.g. for vehicles, containers, the construction and the marine industry.
Furthermore this product is used as a potting, filling and coating compound.
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.
