Two Solar Awards

Sika recently received two awards at this year’s SNEC Solar Exhibition and Conference in Shanghai, China. One was the "Top 10 Highlights - MW Award" for “Sikasil®AS-780 – the liquid tape” and the other the “Best Poster Award - PV Modules” for the poster presentation by Michael Niederfuehr entitled “High initial green strength adhesives - A way to reduce process costs and increase product durability”. These two awards show that adhesive technology and its potential for the PV sector have been well recognized by experts and the industry.

Optimized processes

The key message in both cases was the potential that adhesive technologies offer for reducing costs, optimizing processes and increasing durability. Using suitable adhesives, the PV module industry can achieve these advantages by bonding back rails or other mounting devices to modules during module production.

Savings on time and material

Sikasil®AS-780 combines the exceptional long-term performance of a structural silicone used in the facade industry with the process ability of an adhesive with high tack and high green strength. The initial green strength and strength development is much higher than with existing silicone technologies. The product permits bonding of the mounting devices and handling of the assembled parts within the standard production lines and cycles without the need for any large buffer zones or pre-fixation devices.

This produces material and labor savings of up to 25% compared to common framing and mechanical installation systems, and installation time is reduced by as much as 40%.

Long-term performance

At the same time Sikasil®AS-780 meets the requirements of the EOTA ETAG 002, the severest structural glazing standard for facades, which stipulates a lifetime expectation of at least 25 years on the tested system. With the corresponding joint geometry, the bond will last for decades under harsh environmental outdoor conditions exposed to UV, rain and heat as well as under wind and snow loads.
