Applications in the solar modules sector

In recent years, the efficiency in the production of photovoltaic modules has continuously increased. At the same time, the quality of the modules has improved. Elastic RTV-1 and RTV-2 silicone adhesives have made a significant contribution to this: the adhesives in bonding the module frame and the elastic, fast-curing RTV-2 potting materials when potting the junction boxes.

Bonding thin-film modules

The bonding of thin-film modules requires special product and application knowledge in order to ensure a permanently stable roof and facade integration. OTTO offers the right UV and weather-resistant adhesive systems in a wide range of container sizes for practical handling.

  • UV stability
  • Easy processing
  • One or two component adhesives
  • High and permanently reliable product properties
  • Very wide range of adhesion

Bonding of solar modules in roof tiles

Elastic 1K and 2K silicone adhesives enable special photovoltaic modules to be used reliably as roof tiles. The high weather and UV resistance ensures a stable connection with perfectly adapted properties.

  • Fail-safe, permanent connection of components & substrates
  • Compensation for different thermal material properties
  • Permanent seal against moisture
  • UV stable

Bonding of module frames

Elastic 1-component and 2-component silicone adhesives can shorten the cycle times of frame bonding and reduce the number of work steps. The adhesives are optimally adapted to the process with respect to viscosity, mechanics and adhesion and impress with a quick material application and fast curing.

  • Fail-safe permanent connection of components & substrates
  • Perimeter edge protection
  • Compensation of different thermal material properties

Bonding of junction boxes

The use of silicone-based 1-component and 2-component adhesives leads to a permanently reliable bonding interface between the junction box and the back wall or glass.

  • Permanent sealing against humidity
  • Very good plastic bonding
  • Fast curing

Potting of junction boxes

Thanks to the perfect adjustment of the viscosity of our potting materials to the shapes of junction boxes, these can be filled without any bubbles, avoiding cavities. A high elasticity of the potting materials also reduces the mechanical strain on the interior and supports a long-term, failure-free operation of junction boxes.

  • Fire retardant
  • Dielectric strength
  • Moisture protection

Applications in the solar thermal collectors sector

Solar thermal systems are exposed to heat and cold, sun and rain, storms and hail as well as UV radiation. This places high demands on all of the product components of the solar collectors. Silicone adhesives and sealants from OTTO also prove themselves even under these extreme conditions. The quality OTTO brand - it makes the difference.

Bonding of solar thermal collectors

Thanks to their ability to compensate for thermal linear extension and their temperature and weathering and ageing resistance, elastic silicone adhesives are particularly well-suited for the production of hot water solar collectors. OTTO offers 2-component silicone adhesives in different viscosities and in different pot lives so that the product can be selected depending on the desired process design of the application.

Our product solutions

In the renewable energies sector, we offer different silicone potting materials and adhesives, which are perfectly tailored to the requirements of this application area.
