Saint-Gobain Solar commissioned TÜV Rheinland to evaluate six tape grades for shear adhesion durability in accordance with FINAT Test Method 18. The testing environment closely simulated the actual shear forces of the tape in real world applications and tests were conducted for durability in damp heat and thermal cycling with humidity freeze, as specified in the IEC standards 61215 and 61646. The items evaluated were tapes for framing, junction box and rail bar bonding applications. Appropriate substrates for each application were utilized including aluminium, glass, PET, PVF backsheet and galvanised steel.
In its detailed report, TÜV Rheinland concluded that there were no remarkable changes between the reference test samples and the climatic preconditioned test samples, confirming the suitability of SolarBond Tapes in PV module manufacturing.
With over 30 years of experience, Saint-Gobain Solar satisfies demanding exterior applications requiring technologies with excellent weathering and long-term bonding properties. Increased weatherability, good internal strength and UV resistance are ensured by combining a polymer foam core with advanced acrylic adhesive formulations. These custom designs allow energy and stress to be absorbed along the entire bond area, ensuring that both module and frame maintain isolation for electrical and shock or stress dissipation, making it ideal for PV module applications.
Manufacturers are always looking for ways to enhance productivity, and our tapes provide a solution that meets their needs, says Geoffrey King, Market Manager, Saint-Gobain Solar. Typically, SolarBond Tapes are used in perimeter sealing and bonding of the PV laminate to the aluminium frame, and due to their high-strength acrylic adhesive, instant bonding is achieved, allowing for immediate module handling and increased production efficiency.
