Section 211.1329  Compatible Substrate Primer

"Compatible substrate primer" means either compatible epoxy primer or adhesive primer.  Compatible epoxy primer is primer that is compatible with the filled elastomeric coating and is epoxy-based.  The compatible substrate primer is an epoxypolyamide primer used to promote adhesion of elastomeric coatings such as impact-resistant coatings.  Adhesive primer is a coating that:

inhibits corrosion and serves as a primer applied to bare metal surfaces or prior to adhesive application; or

is applied to surfaces that can be expected to contain fuel.

Fuel tank coatings are excluded from this category.
