3M’s experts in structural adhesive bonding are here to help you make your aircraft nacelle designs durable, lightweight and efficient to produce. Learn more.
-
Surface Pre-TreatmentThe 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.
Recommended Products:
-
Structural Adhesive Bond Primers3M 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.
Recommended Products:
3M™ Scotch-Weld™ Structural Adhesives Primer EC-3917
-
Structural Adhesive Films and Pastes3M structural adhesives are designed for high pre-bond humidity performance, fracture toughness and peel strength on metals and composites, with flexible cure cycles.
Recommended Products:
3M™ Scotch-Weld™ Structural Adhesive Film AF 163-2
3M™ Scotch-Weld™ Structural Adhesive Film AF 3109-2
-
Core Splice Structural Adhesive Films3M core splice adhesive films are low density structural adhesives that expand to a high strength, low density foam with heat. They are generally used to splice honeycomb cores of differing cell sizes as well as other vertical bonding applications.
Recommended Products:
3M™ Scotch-Weld™ Structural Core Splice Film AF 3024
3M™ Scotch-Weld™ Structural Core Splice Film AF 3002
-
Cocure Films3M Cocure films provide durable erosion protection for composite surfaces and are compatible with heated, de-ice systems. These films can protect the leading edge of the engine nacelle inlet from rain erosion and minor impact damage.
Recommended Products:
3M™ Polyurethane Protective Tape 8730NA
-
Urethane Repair Pastes3M urethane repair pastes are used to quickly repair polyurethane erosion films on parts, eliminating the need to remove and replace the film. These two-part pastes cure to erosion-resistant urethane elastomers and provide long-lasting protection from further damage.
Recommended Products:
-
Fan Track Abradable / Void Fillers3M low-density void-filling compounds can be used to fill cavities and perform as fan track abradable in engine applications.
Recommended Products:
-
Paint Replacement Films3M paint replacement fluoropolymer films are inherently resistant to most aircraft fluids and environmental effects. Used inside nacelles, these films can prevent moisture ingression and aircraft fluid uptake into nacelle honeycomb panels.
Recommended Products:
-
Polyurethane Protective Boots3M polyurethane protective boots provide excellent erosion and impact protection for many aircraft parts and can be created to fit a wide variety of needs. Our portfolio of products includes complex inlet boots, such as F-16 engine inlet and C-130 air-conditioning inlet.
Recommended Products:
-
Void FillersLow-density, temperature-resistant epoxy void filling adhesives are ideal for honeycomb reinforcement and filling mismatched areas on engine nacelles.
Recommended Products:
3M™ Scotch-Weld™ Structural Void Filling Compound EC-3550 B/A FST
-
3M™ Nextel™ Ceramic Fibers3M™ Nextel™ Ceramic Fabrics Nextel ceramics are used to manufacture seals and blankets that help you protect Nacelle components from engine heat and fire.
