Weldtex

A conductive element is an essential component in the bonding layer of dual laminate FRP composite storage and reaction vessels. Placed immediately behind the weld line the conductive element allows the inspection of the integrity element allows the inspection of the integrity of welds in the thermoplastic liner using “spark testing” methods. Spark testing is generally achieved using a hand held high voltage high frequency probe with

- A graphite loaded resin putty behind the weld joints
- Sprinkling graphite talc onto the resin-wetted joints
- The use of a conductive veil directly behind the joints

- Low cost
- Quick and easy to apply
- Clean - no health and safety hazards from handling or mixing of carbon black or graphite talc
- No effect on final laminate properties
- Fully compatible with all resin systems
- Fully compatible with all reinforcing laminates
- Light weight
- Precise width and thickness
- Consistent conductivity
- Operator independent
- Effective for the whole life of the vessel
