ADHESIVES AND SEALANTS FOR PHOTOVOLTAIC AND SOLAR THERMAL

ADHESIVES AND SEALANTS FOR PHOTOVOLTAIC AND SOLAR THERMAL

KÖMMERLING has access to a wide range of technologies in the field of functional organic materials for bonding, sealing and insulation. These technologies are key to the successful design, production and marketing of solar panels. The different systems are fully compatible with one another with regard to processing and product design. photovoltaic AND SOLAR TECHNOLOGY In the area of panel sealing, the focus is on the protection of components against ageing and functional losses due to environmental factors. The adhesive bonding technology allows the bonding of very different materials without compromising their inherent cohesiveness and also offers the possibility to reduce tension. The KÖMMERLING HelioSeal and HelioBond technologies are the result of decades of experience in related fields such as insulating glass, roof glazing and transportation. KÖMMERLING stands for outstanding adhesive performance, excellent mechanical properties, consistent quality and superior long-term durability of its products. PRODUCT OVERVIEW HelioSeal Base Properties Applications UL-listed PVS 100 Modified PIB Moisture vapour barrier, desiccant inside Dual sealed PV modules in combination with PVS 101 Modified PIB Moisture vapour barrier, desiccant inside High volume resistivity Single sealed thin film PV modules Multi layer PVS 106 PIB Moisture vapour barrier, desiccant inside High volume resistivity PVS 210 1-part Silicone alkoxy curing UV resistant Excellent ageing resistance High elongation Wide adhesion range Sealing of ribbons and junction boxes Installation sealant for PV modules Frame assembly and bonding of the junction box HelioBond Base Properties Applications UL-listed PVA 200 2-part Silicone UV resistant High modulus Fast curing PVA 205 1-part Silicone oxime curing UV resistant High modulus PVA 303 AT Acrylate Acrylic Tape High immediate adhesion High strength Peel and stick PVA 400 MS-Polymer Good adhesive properties Overpaintable (see Technical Data Sheet) PVA 500 2-part Polyurethane High modulus Fast curing PVA 600 BT Thermal Set Butyl Adhesive Tape High tack Peel and stick Structural adhesive for PV modules Dual Seal Back rail bonding Manufacturing and installation of PV modules Frame assembly and bonding of the junction box Frame assembly and bonding of the junction box Assembly aid Silicone free bonding and sealing of PV and solar thermal components Back rail bonding Extensive bonding of flexible PV modules on roofs

HELIOSEAL / HELIOBOND ADHESIVES AND SEALANTS FOR PV MODULE ASSEMBLY SUPERIOR SEALING SYSTEM Single Seal technology HelioSeal PVS 101 is especially suitable for sealing thin film modules against moisture. The multi layer technology offers new possibilities to the PV industry for module design (crystalline as well as thin film). This technology is an excellent solution when passing the exit ribbons through the edge of the module ideal for BIPV (Building Integrated Photovoltaics). Furthermore the additional bonding with HelioBond PVA 200 allows the production of laminate free modules. HelioSeal PVS 101 Modified PIB Water vapour barrier High volume resistivity Additional chemical bonding Processable as hotmelt or tape Excellent long term stability 2-part Silicone Structural bonding Meets the requirements of ETAG 002 High modulus

BONDING AND SEALING OF THE JUNCTION BOX / HelioBond PVA 205 / HelioSeal PVS 210 1- and 2-part Silicones for the bonding of the junction box Neutral curing Excellent long term stability Wide adhesion range High strength HelioBond PVA 303 AT Acrylic Tape for fixing and bonding of the junction box Easy handling (peel and stick) High immediate adhesion HelioSeal PVS 106 PIB for sealing of exit ribbons Water vapour barrier High volume resistivity BACK RAIL BONDING 2-part Silicone for the bonding of PV modules to the mounting system Structural bonding High load capability Meets the requirements of ETAG 002 HelioBond PVA 500 2-part Polyurethane for the bonding of PV modules to the mounting system Silicone free High creep strength FLEXIBLE MODULES HelioBond PVA 600 BT Adhesive Tape for bonding of flexible PV modules Easy handling (peel and stick) High tackiness Good adhesion to metals and polymer roofing membranes

FRAME ASSEMBLY Long term stability The key is keeping humidity away from the edge of the PV module. With HelioSeal PVS 106 in combination with we can offer an outstanding solution. HelioSeal PVS 106 PIB for joint dimensioning and assembly aid Additional water vapour barrier 2-part Silicone for bonding PV modules into the frame Established in Structural Glazing SOLAR THERMAL THE KEY FOR TIGHT MODULES The bonding of glass to aluminium is extremely demanding. In particular the different thermal expansion behaviour of both substrates requires elastic bonding avoiding extensive stress. The products in our HelioBond range are especially formulated to cope with this requirement. In addition they also act as a seal to the solar panel and show outstanding long term performance against harsh ambient environments. / HelioBond PVA 205 1- and 2-part Silicones for the bonding of cover glass to frame Neutral curing Very good long term stability Wide adhesion range High strength HelioBond PVA 400 1-part Hybrid Polymer for bonding and sealing of the base sheet Silicone free Wide adhesion range Overpaintable (depending on the paint system) For a faster curing also available as a 2-part system
