What is BS EN 4687 about?
The type of primer that you use on fibre or metal-based vehicles would depend on many factors. BS EN 4687 specifies the requirements for a two-components, chromate and lead-free primers for aerospace applications.
The primer and lead-free coatings applies to fibre reinforced composite materials, titanium, corrosion-resistant steels and other suitably prepared corrosion-resistant substrates.
Who is BS EN 4687 for?
BS EN 4687 on paints and varnishes for aerospace (primer) is applicable to manufacturers who supply carriers and similar products to the defence sector. BS EN 4687 is useful for:
- Paint and primer manufacturers
- Quality control personnel for primers
- Design engineers for military aircrafts
- Quality control personnel for military aircrafts
- Aircraft manufacturers
Why should you use BS EN 4687?
The primer coating is the layer between the substrate and the paint. It needs to be compatible with both layers. Lead and chromate-free primers provide anti-corrosive properties and extend the life of the product.
As a paint manufacturer, you would use BS EN 4687 to ensure that the primers that you are manufacturing for aerospace carriers, adhere to the specification. The primer should be free of lead and chromate. It needs to cure at room temperature.
As a manufacturer of metal or fibre carriers, you would use BS EN 4687 to understand which primer is suitable for which aircraft component. Also, you will be able to demonstrate the reliability of your products and build trust throughout the aerospace supply chain.
