Overview
EN 2436-003:2006 is a European standard established by CEN, specifying the requirements for a two-component, cold curing, chromate-free primer used in aerospace applications. This primer is formulated either as an epoxy or polyurethane system, designed to provide high corrosion and fluid resistance for aerospace metal surfaces, primarily aluminium alloys. The primer offers protection either as a standalone coating or as a base layer under finishing paints.
The standard serves an important role in aerospace material coatings by promoting safer, environmentally friendly primer formulations that eliminate chromate compounds, known for their toxicity, while ensuring durability, corrosion resistance, and chemical protection under demanding conditions typical of aerospace environments.
Key Topics
Two-Component System: The primer consists of a base resin combined with an activator, mixed in defined ratios. It cures at ambient temperature, facilitating easy application and use.
Chromate-Free Composition: Ensures compliance with modern environmental and safety regulations by avoiding chromate-based corrosion inhibitors traditionally used in aerospace primers.
High Corrosion Resistance: Tested on aluminium alloy substrates prepared according to EN 3837 and ISO 3270, offering robust protection against corrosion including resistance to salt spray, filiform corrosion, and fluid exposure.
Fluid Resistance: Demonstrates strong resistance to common aerospace fluids, such as tri-n-butyl phosphate, hydraulic fluids, and water, preventing blistering, softening, or film detachment.
Cold Curing: Cold curing capability allows application and curing at ambient temperatures, improving operational flexibility compared to heat-cured primers.
Compatibility: Suitable for use with or without a finishing topcoat, enabling versatile application tailored to specific aerospace needs.
Quality Assurance and Testing: The standard outlines rigorous batch release and qualification testing protocols including physical, chemical, mechanical, and environmental performance tests to maintain consistent product quality.
Applications
EN 2436-003:2006 primers are highly applicable within:
Aerospace Industry: Protecting aircraft structural aluminium alloys from corrosion and chemical degradation during manufacturing, assembly, and service life.
Aircraft Maintenance and Repair: Providing a reliable primer layer for refinishing and maintenance operations requiring chromate-free alternatives.
Manufacturing: Used in aerospace component production lines where cold curing and tight environmental compliance are critical.
Surface Protection: Ideal for aerospace parts subject to exposure to harsh fluids and corrosive environments such as fuel, hydraulic fluids, and varying temperature extremes.
The primer’s properties enable longer lifecycle for aluminium components by preventing corrosion induced failures and reducing maintenance needs associated with corrosion-related damage.
