High initial green strength silicone adhesives designed for in-process bonding of backrails or other mounting devices to PV modules and CSP mirrors are unique compared with other bonding technologies in the market.It combines the exceptional long term performance of a structural slicone used in the facade industry with the process ability of a high tack and high initial green-strength adhesive.Such materials follow the demand for cost and material savings,simplified production processes and secured long term performances to reduce the overall PV system costs.To reduce these overall costs,the industry looks more and more into alternative fixation solutions like backrails or mounting interfaces.So far there was no technology available which meets both,the process ability and the desired long term performance.But to assure a well performing system,in production and in the field,both characteristics are required.On one hand there are existing tape solutions which enable a fast processing and handling but the long term performance and needed tolerance compensation is very limited.On the other hand the long term durability can be provided by Silicone technologies but they are very limited in the process as they need pre-fixation devices and/or larger buffer zones for curing.Due to the high initial green-strength of new technology the bonding application can be integrated into the production lines with a fast handling afterwards.
