In order to meet the requirements for a permanent joint of frame profiles and corner brackets, the adhesive must not only cure very quickly, but above all show excellent adhesive power on the metals used.
The high bonding strength of corner joints of P 520 is confirmed by a test certificate issued by the Institute for Window Technology Rosenheim, Germany (ift Rosenheim).
The corner connection resisted an applied load of 1.400 kg after only 24 h curing time.
The static mixer fitted onto the twin cartridge makes P 520 is not only easy to use but also ensures the right mixing ratio and a very homogeneous blend.
Since P 520 once cured is not brittle, but remains permanently viscoplastic, the bonding shows outstanding knock and shock resistance.
