3M has long been the supplier of choice for challenging helicopter rotor blade bonding and surface protection applications. Learn more.
Our world class surface preparation, structural adhesive bond primers, films and erosion protection films are approved and trusted by rotorcraft OEMs worldwide. They provide toughness, durability and resistance to temperature, minor impacts and erosion in some of the harshest and most challenging of environments.
The 3M sol-gel products provide surface treatment and adhesion enhancement performance on metal substrates on par with conventional chemical etch and anodize systems. Enables “on-wing” surface preparation for metal bond applications for challenging substrates such as aluminum, titanium, nickel and stainless steel. Complimentary to 3M corrosion inhibiting bond primers such as EW-5005 and EC-3917.
3M corrosion inhibiting bond primers ensure long term durability for the bonded substrates. These products are available in conventional solvent based chromated versions as well as water based chromated and non-chromated versions. They are compatible with both conventional etch and anodize surface preparations as well as grit blast-sol gel.

3M Cocure films provide built-in erosion protection of composite rotor blade surfaces. Able to co-cured with the composite skin or bonded to the surface of the rotor blade, these films provide a more durable alternative to paint or other coating systems and can be used on composite surfaces including leading edges and blade tips.
