Insulcast

Insulcast Features and Applications

Substrates

• Metals: aluminum, steel, copper, brass
• Plastics: ABS, polycarbonate, nylon, acrylic
• Glass, ceramics, and PCB substrates
• Potting cups, cases, and molded housings

Applications

• Ignition coils and transformers
• Printed circuit board potting and encapsulation
• EV battery modules and power electronics
• High voltage power supplies
• Heat sink bonding, surface mount, and die attach
• Telecom, utility, and power generation equipment
• Aerospace and defense electronics

Key Features

• Insulcast 116 FR: 1:1 by weight general purpose epoxy, UL 94V-0, 90 minute pot life, good fit for hand mixing or automatic dispensing.
• Insulcast 116 FR FC: same 1:1 chemistry with a 30 to 45 minute pot life and 16 hour room temperature cure for faster line turns.
• Insulcast 140 FR: 2.3 W/mK thermal conductivity and service from -55 C to 155 C for dense assemblies that run hot.
• Insulcast LN 1-05: non-cracking epoxy built for large pours, 8 to 10 hour pot life, UL 94V-0.
• Insulgel 70 CC FR NS: flexible epoxy with high elongation and low CTE, an alternative to urethane without isocyanate exposure.
• RTVS 27 series: low viscosity silicone potting from -55 C to 204 C, easily cut away for component repair. FC (fast cure), LV (gap filling), and HTC (1.0 W/mK) variants available.
• RTVS 3-95-1 and 3-95-2: high thermal conductivity silicones to 1.44 W/mK with service to 260 C, suited to EV and high voltage applications.
• RTVS 42 Curtis II: silicone-epoxy copolymer that resists thermal shock cracking and bonds well to most metals and plastics.
• Insulcure hardeners: Insulcure 9, 11B, 20, 24, and 26 set pot life from 45 to 300 minutes on compatible epoxy systems.
• RTVS 41 and RTVS 44 primers: improve silicone adhesion on metal, wood, glass, ceramic, and many plastics.
