EN 2436-006:2006 - Overview

EN 2436-006:2006 is a CEN aerospace standard specifying a two-component, chromate- and lead‑free, cold‑curing epoxy primer formulated for high corrosion resistance in military applications. The primer is intended for use on chromic acid anodised or conversion‑coated aluminium alloys, fibre‑reinforced composite materials and other suitably prepared substrates. The standard sets material, performance, testing and batch release requirements to ensure consistent corrosion protection for aerospace structures.

Key topics and technical requirements

• Material scope: Two‑component epoxy system (base + activator ± thinner), chromate‑free and lead‑free, designed for aerospace corrosion protection.
• Application parameters: Typical dry film thickness 25 ± 5 µm; components mixed in whole‑number ratios per manufacturer instructions; cold (room temperature) curing.
• Classification:
  • Type I - standard solvent content
  • Type II - low VOC (≤ 350 g/L)
  • Class A - standard pigments
  • Class B - low infrared reflective pigments
• Batch release & qualification: Qualification requires testing of a minimum of three batches; batch acceptance tests are defined for production control.
• Delivery and physical tests: Non‑volatile matter, VOC (Type II), flash point, density, fineness of grind, sedimentation, flow time, pot life and appearance checks.
• Film performance tests: Cross‑cut adhesion, scratch resistance, bend/cupping/slow deformation tests, colour and IR reflectance as agreed with purchaser.
• Environmental and corrosion resistance: Thermal exposure, humidity/condensation, water immersion, neutral salt spray (e.g., 3 000 h Procedure B or 1 000 h Procedure A/C as specified), alternate immersion, and filiform corrosion resistance - all with defined acceptance criteria (e.g., limits on blistering, scribe corrosion and adhesion).
• Resistance to fluids: Exposure to system fluids such as hydraulic oil (NATO H‑515) with specified performance limits.
• Relevant test standards: Normative references include EN 3837 (surface preparation), EN 2435‑005/EN 2434‑005 (related aerospace coating standards) and numerous ISO methods for paint testing.

Practical applications and users

• Primary users: Aerospace and defence manufacturers, paint formulators, military procurement/specification engineers, maintenance/repair organizations, qualified coating applicators and quality assurance teams.
• Use cases: Primer specification for structural airframe components, repairs and new builds that require chromate‑free corrosion protection suitable for military performance demands and environmental exposure.

Related standards

• EN 2435‑005 - chromated two‑component cold‑curing epoxy primer (comparator)
• EN 2434‑005 - related top‑coat system referenced for filiform testing
• EN 3837 - surface preparation for aluminium substrates
• ISO/EN test methods for salt spray, humidity, adhesion, VOC and other coating properties
