The glue used for all elastomers (except Viton and Barriquant plates) is 3M 9323 (bi-compound glue). This glue can polymerize at room temperature.
Due the geometry of Barriquant plates use 3M 1099.

Plate Heat Exchanger Cleaning Procedure
Possible Causes from Bad Gluing
Workmanship:
- Discrepancy from horizontal position
- Wrong application of glue
- Wrong fastening of gaskets with tape
- Wrong alignment of plates
- Insufficient guiding of plate stack
- Wrong curing temperature, pressure and time
- Unsatisfactory tightening during curing
- Uneven temperature distribution in the case of curing oven
- Too early unloading of pressure on plate stack (when still hot)
- Careless handling of plates
- Unsatisfactory cleaning prior to gluing
- Unsatisfactory cleaning of gasket groove
- Use of unsuitable cleaning agents
- Too loose tightened of plates pack
Plate material:
- Geometry - deformation
- Pre-treatment (bright annealed surface for example)
- Insufficient cleaning soiling (airborne or condense)
Gasket cement:
- The properties do not suit the operating conditions (liquids, temperature and pressure).
- The properties do not suit the rubber quality.
- The properties do not suit the plate material (corrosion)
- Exceeded shelf life
- Exceeded pot life
- Insufficient mixing
- Bad storing conditions
- Wrong quantities or misdistribution - special care has to be taken by thin plates with shallow gasket grooves.
- Insufficient or exaggerated evaporation of solvent
- Quality error
- Wrong proportion of components in the case of 2 component glue
