BS EN 4688:2021 Aerospace Series: Corrosion Resistant Epoxy Primer

Introducing the BS EN 4688:2021, a cutting-edge standard in the aerospace series that sets the benchmark for paints and varnishes designed to withstand the harshest conditions. This standard focuses on a corrosion-resistant, chromated, two-component epoxy primer that cures at room temperature, offering unparalleled protection and durability for military applications.

Unmatched Corrosion Resistance

In the demanding world of aerospace and military applications, the need for materials that can endure extreme environments is paramount. The BS EN 4688:2021 standard addresses this need by specifying a primer that provides high corrosion resistance. This makes it an ideal choice for protecting aircraft and other military equipment from the damaging effects of corrosion, ensuring longevity and reliability.

Advanced Two-Component Epoxy Primer

The primer outlined in this standard is a two-component system, which means it consists of two separate parts that, when mixed, create a chemical reaction resulting in a robust and durable coating. This type of primer is known for its excellent adhesion properties and its ability to form a tough, protective barrier on a variety of surfaces.

Room Temperature Curing

One of the standout features of the BS EN 4688:2021 standard is the specification of a primer that cures at room temperature. This characteristic is particularly advantageous in environments where temperature control is challenging or where rapid application and curing are required. The ability to cure at ambient temperatures without the need for additional heat sources makes this primer both versatile and cost-effective.

Military Application

Designed with military applications in mind, the primer specified in this standard is engineered to meet the rigorous demands of military environments. Its high corrosion resistance ensures that military equipment remains operational and effective, even in the most challenging conditions. This makes it an essential component in the maintenance and protection of military assets.
