A phenolic primer is a substance applied as a preparatory coating layer on a metal surface to prevent the absorption of additional coating layers that will be applied later. It performs via thermosetting and is generated by the reaction of a phenol with an aldehyde.
A phenolic primer works as a fast-drying coating that is applied to metal surfaces to prevent corrosion. It is formulated to adapt to various topcoats and is applied prior to the topcoat application. Its service is optimized on metal surfaces that are exposed to oxygenated atmospheres.
