Since 2013 McConnell Seats have been using Hilustre Powder Coatings to paint grab rails for use in Victorian trains. The spray paint system is applied by Hilustre to meet the quality specification using a PPG two pack paint system.
This comprises 3 coats of epoxy primer to adhere to the cast aluminium grab rail, this is inspected for blemishes and sanded smooth. Then the grad rails are top coated with the anti-graffiti resistant polyurethane top coat. The grab rails are then inspected to meet the stringent requirements of their client and packed ready for installation.
These pictures show primed grab rails and the yellow top coat being applied.
