Wacker launches range of silicones for photovoltaic industry

ERJ staff report (DS)

Munich, Germany -- Wacker Group has introduced a new product line geared specifically to the needs of the solar industry. Marketed under the name Elastosil Solar, the line includes several silicone grades. The novel products include a UV-activated specialty silicone as well as pourable, highly translucent silicone elastomers for moulding optical parts employed in high-concentration photovoltaic modules.

Wacker said all Elastosil Solar grades are resistant to weathering, radiation and heat, making them ideal for bonding, sealing, laminating and encapsulating photovoltaic modules and their electronic components.

Among the products is Elastosil Solar 2120 UV encapsulant. This is a UV-activated silicone elastomer that cures at room temperature without any additional heat. Curing of the silicone encapsulant at room temperature - until now a time-consuming process - is effected in just a few minutes, given a UV light source.
