PU 407

PU 407 is a rigid polyurethane casting system formulated for high-load or industrial filter frames. It delivers superior mechanical strength, impact resistance, and dimensional stability — even in high-temperature environments.

Technical Features:

•Mixing Ratio (A:B): 100:100

•Saves up to 15% material per gasket

•Viscosity: High (more rigid, dense foam structure)

•Gel Time: ~45–60 seconds

•Hardness (Shore A): 85–90

•Key Benefits: High rigidity, strong bonding, ideal for large or thick-frame filters
