Overview

EN 2781:1998 is a European standard developed by CEN that specifies test methods for determining the primer thickness used in structural adhesives, particularly within the aerospace industry. This standard is part of the aerospace series focussing on non-metallic materials and plays a crucial role in ensuring adhesive performance and reliability in high-stress structural applications. Accurate measurement of primer thickness directly impacts the adhesion quality and durability of bonded joints, which are vital for aerospace safety and structural integrity.

Key Topics

  • Primer Thickness Measurement: Defines standardized procedures for assessing the thickness of primers applied to bonding surfaces prior to adhesive application.
  • Test Methods: Provides detailed methodologies that ensure repeatability and accuracy in measuring primer coatings.
  • Non-Metallic Materials: Targets structural adhesives used with composite and other non-metallic aerospace materials.
  • Quality Control: Enables manufacturers and engineers to verify primer application consistency to meet strict aerospace quality standards.
  • Aerospace Adhesives: Addresses adhesives designed for critical aerospace structural components requiring reliable bonding.

Applications

  • Aerospace Manufacturing: Used by aerospace manufacturers to test and control primer coatings on non-metallic components that require structural adhesive bonding.
  • Quality Assurance Labs: Laboratory environments conduct testing per EN 2781 to certify primer thickness and ensure compliant adhesive preparation.
  • Composite Structures: Essential for achieving optimum adhesion of primers on composite materials used in aircraft fuselage, wings, and interior components.
  • Maintenance and Repairs: Applied during aircraft structural repairs to verify that primer thickness meets original manufacturing standards.
  • Research and Development: Facilitates adhesive performance studies by providing a baseline for primer thickness influencing bond strength.
