Engineered for applications requiring optical clarity, low outgassing, and minimal thermal contraction, the LCA-4 system provides exceptional bond strength to glass, quartz, metals, ceramics, and rigid plastics. Curing at room or elevated temperatures, LCA-4 maintains high dielectric strength and chemical resistance across demanding thermal cycles (-65°F to 300°F). Ideal for bonding glass covers, sealing optical sensors, encapsulating LED arrays, and staking micro-components in flight deck instruments and satellite payloads.\u003c\/p\u003e\n\n    \u003chr\u003e\n\n    \u003ch3\u003eTechnical Specifications \u0026amp; Chemical Properties\u003c\/h3\u003e\n    \u003cul\u003e\n        \u003cli\u003e\n\u003cstrong\u003eManufacturer \/ Brand:\u003c\/strong\u003e HB Fuller \/ Bacon Adhesives\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eProduct Name \/ Part Number:\u003c\/strong\u003e LCA-4 Kit (Liquid Resin \u0026amp; Hardener)\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eChemical System:\u003c\/strong\u003e Two-Part Unfilled Clear Epoxy System\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eMix Ratio (Resin to Hardener):\u003c\/strong\u003e 100 : 8.5 by weight\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eViscosity (Mixed):\u003c\/strong\u003e Low viscosity (~300 to 600 cPs) for excellent penetration and bubble-free potting\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eOptical Clarity:\u003c\/strong\u003e Clear to light straw liquid with high light transmission post-cure\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e -65°F to 300°F (-54°C to 149°C) post-cure continuous service\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eCure Schedule:\u003c\/strong\u003e 24 hours at 77°F (25°C) or 2 hours at 150°F (65°C) for accelerated processing\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eShore D Hardness:\u003c\/strong\u003e ~85 Shore D\u003c\/li\u003e\n    \u003c\/ul\u003e\n\n    \u003ch3\u003eApproved Specifications \u0026amp; Aerospace Conformance:\u003c\/h3\u003e\n    \u003cp\u003eThe HB Fuller Bacon Adhesives LCA-4 Kit meets rigorous defense and space qualification baselines:\u003c\/p\u003e\n    \u003cul\u003e\n        \u003cli\u003e\n\u003cstrong\u003eNASA Outgassing Conformance:\u003c\/strong\u003e Fully tested to ASTM E595 standards (TML \u0026lt; 1.0%, CVCM \u0026lt; 0.10%) for low-outgassing optical and spaceflight applications.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eMilitary Avionics Qualified:\u003c\/strong\u003e Meets major defense contractor process standards for optoelectronic sealing and glass-to-metal bonding.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eEnvironmental Resistance:\u003c\/strong\u003e Resists moisture absorption, jet fuel, synthetic lubricants, and mild solvents without clouding or bond degradation.\u003c\/li\u003e\n    \u003c\/ul\u003e\n\n    \u003chr\u003e\n\n    \u003ch3\u003eKey Features \u0026amp; Performance Benefits\u003c\/h3\u003e\n    \u003cul\u003e\n        \u003cli\u003e\n\u003cstrong\u003eLow-Outgassing Optical Formulation:\u003c\/strong\u003e Prevents lens fogging and volatile condensation on sensitive optical sensors in high-vacuum or sealed avionics enclosures.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eUltra-Low Viscosity \u0026amp; Deep Penetration:\u003c\/strong\u003e Flows effortlessly into narrow gaps and complex microelectronic assemblies for void-free encapsulation.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eHigh Dielectric Isolation:\u003c\/strong\u003e Shields delicate electronic circuits and optical sensors from electrical breakdown and stray voltage leakage.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eExcellent Dimensional \u0026amp; Thermal Stability:\u003c\/strong\u003e Maintains structural bond integrity and optical clarity under severe thermal shock and flight vibration.\u003c\/li\u003e\n    \u003c\/ul\u003e\n\n    \u003chr\u003e\n\n    \u003ch3\u003eTypical Applications\u003c\/h3\u003e\n    \u003cul\u003e\n        \u003cli\u003e\n\u003cstrong\u003eOptoelectronic \u0026amp; Display Assembly:\u003c\/strong\u003e Lamination and bonding of glass faces, optical filters, lenses, and display windows on flight deck screens.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eSensor Encapsulation \u0026amp; Sealing:\u003c\/strong\u003e Potting and sealing IR sensors, photodetectors, laser optics, and fiber optic interconnects in missile guidance and aerospace systems.\u003c\/li\u003e\n        \u003cli\u003e\n\u003cstrong\u003eMicroelectronic Component Staking:\u003c\/strong\u003e Securing delicate wire bonds, quartz crystals, and surface-mount devices on PCB assemblies.\u003c\/li\u003e\n    \u003c\/ul\u003e\n\n","brand":"HB Fuller","offers":[{"title":"Quart Kit","offer_id":56511783305588,"sku":"LCA-4-1QT-KIT","price":875.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/145.aero\/products\/hb-fuller-bacon-adhesives-lca-4-epoxy-adhesive-kit","provider":"Aircraft Shop Supply","version":"1.0","type":"link"}
