Primax SE 91 is an epoxy-polyester especially formulated powder coating designed to be used as a primer coat on casting metal substrates based on aluminum alloys, to enhance their resistance to corrosion when exposed to severe climatic conditions, in particular sea-side and high snowy areas.

Primax SE 91 reduces blistering and other surface defects that occur during the powder curing process in most common types of aluminum-alloy castings, as they are exposed to high temperatures. Primax SE 91 also provides outstanding edge coverage, very good flow and excellent inter-coat adhesion.

Primax SE 91 is formulated to be over-coated with powder top coats such as Corro-Coat PE, Corro-Coat PE-F or Corro-Coat PE-SDF Super Durable providing excellent mechanical and chemical performance with superior flow and finish for outdoor applications.

Application areas
Primax SE 91 is recommended as a primer coat on cast aluminum-alloys such as die-casting, permanent mold casting and sand casting, to enhance their appearance and performance. Typical application areas are lighting fixtures and posts, fences, garden furniture, display panels and small electrical boxes.
