Alseal coatings are offered with non-metallic pigments that can be used to form an insulating layer, protecting metal substrates from heat or electricity.

Alseal 528
Acts as a thermal barrier coating (TBC) on the coated surface when the uncoated side of the part is actively cooled. Also effective as an electrical insulator. Functions in environments up to 1400oF (760oC).

Alseal 518
Non-electrically conductive coating, functions in environments up to 1000oF (538oC).
