SUN MIROX by AGC Solar is extra clear extra thin glass for parabolic dish and parabolic trough collectors.

Solar Mirror Thin

Extra clear extra thin glass mirror for parabolic dish, parabolic trough collector, CSP and CPV

Type

 

 

Extra clear extra thin glass mirror

 

Applications

 

 

Parabolic dish, parabolic trough collector,
CSP or CPV (laminated)

 

SOLAR MIRROR THIN is an extra clear extra thin high reflectivity mirror perfectly suited for lamination purposes and use in parabolic dish, parabolic trough collector, CSP or CPV. Once laminated with an appropriate adhesive onto a support material the mirror is perfectly well protected and shows a very high chemical and mechanical durability.

SOLAR MIROX THIN conforms to EN1036. AGC can suggest you a set of qualified adhesives in function of your support structure.
