What is BS EN 2436-004 - High corrosion and fluid resistant primer with surface preparation tolerance about?
BS EN 2436-004 is a standard that covers high corrosion and fluid resistant primer with surface preparation tolerance, enabling the application of primer on little or no prepared surfaces with any humidity and wet surfaces.
BS EN 2436-004 specifies the basic requirements for two components, cold curing, chromate-free epoxy or polyurethane, high corrosion and fluid resistant primer with improved tolerance to the standard of surface preparation which can be used with or without a finish for aerospace applications.
The properties specified in BS EN 2436-004 are obtained on defined aluminium alloy test pieces prepared in accordance with EN 3837, process D and ISO 3270.
The ability of the material to be used for a specific application (e.g. alternative substrate, alternative primer, specific drying conditions etc.) shall be determined by supplementary tests to confirm that the requirements of BS EN 2436-004 are met.
Who is BS EN 2436-004 - High corrosion and fluid resistant primer with surface preparation tolerance for?
BS EN 2436-004 on high corrosion and fluid resistant primer with surface preparation tolerance applies to:
- Manufacturers of products and equipment in aerospace industry
- Quality assurance services
- Suppliers of paints and varnishes in aerospace applications
- Coating and painting services in aerospace industry
- Aerospace and aeronautical engineers
- Maintenance and repair services
Why should you use BS EN 2436-004 - High corrosion and fluid resistant primer with surface preparation tolerance?
A primer is a base coat that is applied to a surface to help treat it before adding a topcoat. As a result, the primer is designed to provide maximum adherence. Surface tolerance is the cleanliness, receptiveness and effectiveness of metal to apply coating on its surface. The efficiency of a corrosion prevention coating is proportional to the tolerance of the surface.
BS EN 2436-004 provides users guidance on batch release and qualification testing of primers to ensure quality and performance in coating applications.
BS EN 2436-004 provides users guidance on physical and chemical characteristics of primers including, condition, finish, sedimentation rating, pot life, viscosity, fineness of grind, non-volatile matter, flash point and more, to ensure the quality, applicability and durability of primer coatings.
BS EN 2436-004 also provides users guidance on mechanical characteristics, including adhesion, scratch resistance, bend test cylindrical mandrel, slow deformation and impact to ensure uniform application and corrosion resistance in primer coatings.
With obedience and compliance to BS EN 2436-004, users can assess and apply primers on components for uniform surface applicability and high corrosion resistance to ensure a longer operating life and prevent the decay of components in aerospace applications.
