Formulated to deliver exceptional mechanical shear strength and long-term durability, this liquid epoxy system is engineered for bonding metallic substrates, advanced composite laminates, honeycomb structures, and rigid synthetics. Loctite A1177B1\/B2 cures at room temperature or under low-temperature heat assist to form a resilient, impact-resistant structural bond line. Its low-exotherm curing profile and outstanding resistance to aviation fluids, environmental humidity, and thermal cycling make it an essential material for airframe maintenance, repair, and precision structural manufacturing.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications \u0026amp; Cross-References\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Henkel Corporation \/ Loctite® Aerospace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e Loctite® A1177 Series (Part A1177B1 Resin \/ Part A1177B2 Hardener)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical Base:\u003c\/strong\u003e Two-Component Structural Epoxy Resin System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhysical Form:\u003c\/strong\u003e Flowable Liquid Paste\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor (Mixed):\u003c\/strong\u003e Off-White to Light Amber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCure Profile:\u003c\/strong\u003e Ambient room temperature cure (24 to 48 hours at 77°F \/ 25°C) or accelerated heat cure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperational Temperature Range:\u003c\/strong\u003e Continuous load-bearing performance up to 180°F (82°C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eViscosity:\u003c\/strong\u003e Medium-viscosity liquid with excellent wetting and gap-filling characteristics\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApproved Specifications \u0026amp; Industrial Conformance:\u003c\/h3\u003e\n\u003cp\u003eLoctite A1177B1\/B2 is qualified across major aerospace manufacturing and defense engineering standards:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommercial Aerospace Specifications:\u003c\/strong\u003e Fully conforms to OEM structural bonding and repair specifications for civil and military fixed-wing and rotary aircraft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid Resistance Profile:\u003c\/strong\u003e Evaluated to maintain bond integrity when exposed to JP-8\/Jet-A fuel, Skydrol hydraulic fluids, synthetic lubricating oils, and deicing fluids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuality Management Baseline:\u003c\/strong\u003e Produced under strict AS9100 and ISO 9001 aerospace manufacturing controls to ensure batch-to-batch consistency and physical traceability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eKey Features \u0026amp; Performance Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Structural Shear Strength:\u003c\/strong\u003e Delivers superior lap shear and peel performance across aluminum, titanium, stainless steel, and carbon-fiber composite joints.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControlled Room-Temperature Cure:\u003c\/strong\u003e Cures reliably at ambient shop temperatures without requiring specialized high-temperature autoclave equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Substrate Wetting:\u003c\/strong\u003e Medium-viscosity formulation thoroughly wets surface profiles, ensuring maximum contact area and void-free bond lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental \u0026amp; Chemical Durability:\u003c\/strong\u003e Resists moisture ingress, galvanic corrosion, and chemical degradation under severe atmospheric flight conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-Exotherm Reaction:\u003c\/strong\u003e Safe for bonding heat-sensitive substrates, thin metal skins, or thick core potting sections without thermal distortion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructural Airframe Bonding:\u003c\/strong\u003e Used for primary and secondary structural bonding of aircraft aluminum skins, stiffeners, ribs, and fairings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposite Laminate Repair:\u003c\/strong\u003e Ideal for repair and reinforcement of carbon fiber, fiberglass, and Kevlar composite panels in MRO facilities.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHoneycomb Panel Construction:\u003c\/strong\u003e Applied as an adhesive or edge-sealing compound for aluminum and Nomex honeycomb core assemblies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Henkel","offers":[{"title":"Default Title","offer_id":55209353675124,"sku":"A1177B1B2PTKT","price":0.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/145.aero\/products\/henkel-loctite-a1177b1-b2-epoxy-adhesive","provider":"Aircraft Shop Supply","version":"1.0","type":"link"}
