Primer definition

Primer means a coating labeled and formulated for application to a substrate to provide a firm bond between the substrate and subsequent coats.
Primer means the first layer and any subsequent layers of identically formulated coating applied to the surface of an aerospace vehicle or component. Primers are typically used for corrosion prevention, environment protection, functional fluid resistance, and adhesion promotion of subsequent coatings. Primers that are defined as specialty coatings are not included under this definition.
Primer means any coating that is designed for application to bare metal or existing finishes to provide corrosion protection prior to application of a primer surfacer:

Examples of Primer in a sentence

  • Primer: Material recommended by joint-sealant manufacturer where required for adhesion of sealant to joint substrates indicated, as determined from preconstruction joint-sealant-substrate tests and field tests.

  • Primer: Product of underlayment manufacturer recommended for substrate, conditions, and application.

  • Primer: Product of topping manufacturer recommended for substrate, conditions, and application.

  • Primer: Non-staining type, recommended by sealant manufacturer to suit application.

  • Universal Shop Primer: Fast-curing, lead- and chromate-free, universal modified-alkyd primer complying with MPI#79 and compatible with topcoat.
