Solar Photovoltaic Cell Manufacturing Compounds
We manufacture resins designed specifically for superior adhesion to photovoltaic (PV) cells. We have a wide variety of solar panel materials, from quick-curing adhesives for attaching the junction box to the PV panel to two-component aliphatic polyurethane compounds with exceptional UV resistance. We also custom formulate adhesives for a wide range of applications.
Adhesives eliminate the need for mechanical fasteners, such as U-bolts and screws, and completely remove the stress points caused by these fasteners. By using our solar panel adhesives instead of mechanical fasteners, the need for constant maintenance and replacement inventory, along with the installation costs, is greatly reduced. Our adhesives can be used not only for assembly of photovoltaic panels but also for attaching the panel frames to the mounting racks.
