Specification for two component epoxy primer for aerospace purposes
This British standard specifies requirements for the materials and performance of two types of strontium chromate pigmented two pack ‘I resin based primer, for air-drying at ambient temperature, for aerospace applications.
Type A materials are intended for application to chemically pretreated substrates (e.g. by a chromate conversion process) suitable for general applications.
Type B materials are similar to type A but with improved tolerance to the standard of surface preparation, and with increased chemical resistance.
The primers are for use on metallic substrates as an anti-corrosive coating on interior surfaces, or, when overcoated with a compatible finish, as a protective and decorative finishing scheme for exterior surfaces.
Information on application for type approval is provided in Annex A.
