BONDING MASTIC AND ACTIVATOR TWIN CARTRIDGE END SEALS

When bonding screeens using a two-pot bonding mastic product, to ensure effective bonding it is essential to

take note of the following observation :

Twin cartridges from large two-pot kits (450 ml) and small kits (220 ml) have pre-cut metal cartridge end seals

(1). These end seals automatically retract when the BETAGUN application gun is operated. When the two

plunger arms are pushed in the cartridge end seals separate from the cartridges and the two products A and

B are pushed to the end of the mixer nozzle (2).

The PU mastic and its activator are then effectively extruded and mixed.

The repair methods given by the manufacturer in this document are based on the

technical specifications current when it was prepared.

The methods may be modified as a result of changes by the manufacturer in the

production of the various component units and accessories from which his vehicles

are constructed".

two cartridges do not operate at the same time

and mixture of the two products cannot be

guaranteed.

The cartridge end seals must not be removed

before the cartridges are fitted into the

application gun.

If the cartridge end seals are not in place, the

application gun is acting directly on the plastic

pistons and before activating the cartridges the

pistons compress the bonding mastic and the

activator.
