Sikagard-834

Sikagard^®-834 for an EV Battery

Product description

Sikagard®-834 is a modified epoxy-based intumescent fire protection coating for electric vehicle (EV) batteries. The solvent-free, 100 percent solids material provides durable corrosion-resistance, as well as protection against thermal events in electric vehicle battery systems.

Sikagard-834 is easily applied with standard airless spray equipment and requires no reinforcement. The fire protection coating cures rapidly to a very tough and resistant finish, and is ready for handling and transport after 24 hours.
