FRAME BONDING

Frame bonding

Solar frame bonding - 1st generation solar module

Solar frame bonding calls for a very durable solution, providing reliable attachment and weather-proof sealing at the same time. For more than a decade our high quality PE foam tapes have been a trusted solution for this demanding application, offering an aesthetic finish and a fast, clean, and simple assembly process thanks to immediate holding strength (no curing time) and no mess associated with liquid glues.

  • Premium product quality
  • Proven durability backed-up by external test reports
  • Tailored dispensing solutions for every company size

Tailored dispensing solutions for frame bonding

IPM-Solar_62510-spool-001_72dpi
01Long-length tape spools

Our spooled tapes in long length and superior slitting quality enable an efficient framing process. They are designed to run in leading automated framing units and facilitate efficient mass production.

IPM-Solar_6095-solar-dispenser
02tesa® 6095 spool dispenser

To support the most efficient processes, our tesa® 6095 semi-automated dispenser unwinds and feeds long length tape spools. This means less roll changes and less waste at a low investment cost and a solution which is very easy to integrate into existing production layouts.

03tesa® edge taper LR

To efficiently apply tape from a pancake roll to the module edge, we recommend our 'tesa® edge taper LR', a precise, easy-to-use, well-proven handheld applicator with a liner removal function.

CELL FIXATION

Cell fixation

Cell fixation - 1st generation solar module

During the lamination process, solar cell strings need to be perfectly aligned and kept in position. Any solution has to withstand the heat required to melt the encapsulant and there cannot be any interaction between the materials in use in order to ensure a bubble-free and homogenous sealing and a perfect adhesion between the different layers of the PV module. Our industry-proven tapes recommended for this application keep cells and strings in place during the lamination process and are especially designed for good compatibility and durability.

tesa® 4129 - Transparent PET tape

  • Low outgassing, temperature-resistant adhesive
  • Thin and conformable design
  • Durable and UV-resistant

HOLE COVERING

Temporary hole covering

Hole covering - 1st generation solar module

During the lamination process, there is a need to mask off holes in the back sheet. Any applied tape needs to securely withstand the high temperatures of the lamination process, and easily remove after the laminate is ready. 

tesa® 50600 - PET film tape with silicone adhesive

  • Bonds to various types of back sheets
  • 220 °C temperature resistance
  • Excellent removability after lamination

EDGE SEALING

Temporary edge sealing

Temporary edge sealing - 1st generation solar module

During the encapsulation process of frameless double glass modules, there is a need for single-sided tapes to prevent contamination of the equipment and form an aesthetic edge. Upon the process' completion, the tape needs to easily remove from the module.

tesa® 50600

  • Good immediate adhesion
  • High temperature resistance
  • Good removability after lamination process

JUNCTION BOX FIXATION

Junction box fixation

Junction box fixation - 1st generation solar module

For temporary bonding of the junction box in combination with liquid adhesives. In addition to the spacer function, our adhesive tapes provide fast initial bonding and help implement a reliable and efficient production process.

tesa® 62510 – Double-coated PE foam tape

  • 1 mm total thickness
  • High immediate bonding strength
  • Good dispensing and die cutting properties

CABLE FIXATION

Cable fixation

Cable fixation - 1st generation solar module

During transport and installation, junction box cables need to be securely kept in place to avoid damage. Any tape used for cable fixation must also be easy to remove after shipping to facilitate efficient installation processes.

tesa® 64283 – MOPP film transport securing tape

  • High adhesion to numerous surfaces
  • Easy removal after shipping
