Description
Solar Rack Maintenance
Coating System ：Primer Sigmashield 880 + Top Coat Sigmadur 550
Surface Preparation ：Hand tools/ Power tools
Application Method ：Brush
Challenge : The rust on rack is serious, and solar panels couldn’t have protective covering during operation when coating it. Also, it’s showering before primer Sigmashield 880 dries.
Owner Feedback ：Sigmashield 880 is an antirust primer which can build high film thickness by one coat, covered with Sigmadur 550 top coat can get an excellent protection.
Contractor Feedback ：Primer Sigmashield 800 is easy to build the thickness, and top coat Sigmadur 550 is easy to cover.
