Beginning with April 2020 deliveries, VHA customers may notice a matte finish on their main and tail rotor blades. VHA has begun applying a new nano hybrid polyurethane (NHP) topcoat to all of its main and tail rotor blade products.
Designed for aviation applications, the NHP topcoat uses a 3D nanoparticle structured chemical formula unlike any previous linear cross-link paint. The result is an extremely durable, flexible, and corrosion-resistant product that resists paint cracking and saltwater corrosion.
