Two-Component Thermal Gel (Curing Thermal Putty)  

Two-Component Thermal Gel (Curing Thermal Putty)  

Two-component thermal gels — also known as curing thermal putty — are designed for applications where both high thermal performance and permanent mechanical stability are required. Unlike single-component gels that stay soft and reworkable, this material cures after mixing into a soft, elastic solid. This allows it to maintain its shape, resist mechanical vibration, and provide long-term durability — even in harsh environments.

Once cured, it delivers reliable heat transfer, shock absorption, and low-stress thermal bridging, all while holding its form between mating surfaces.

Key Features & Benefits:

• 🌡 Medium to High Thermal Conductivity
  Offered in grades ranging from 2.0 to 8.0 W/m·K, suitable for everything from general-purpose heat transfer to demanding power electronics.
• 🧪 Two-Component, Mix-and-Dispense System
  Components A and B are mixed at the point of application, and cure over time into a flexible elastomeric interface.
• 🔧 Post-Cure Stability
  After curing, the material maintains defined thickness and structure, eliminating issues like material pump-out or migration.
• 🧽 Shock Absorption + Gap Filling
  Soft cured form absorbs vibration and mechanical movement, while still conforming well to surface irregularities.
• ⚡ Excellent Electrical Insulation
  Provides high dielectric strength (up to ~8kV/mm), critical for safety in high-voltage systems.
• 🔥 Flame Retardant (UL94 V-0)
  Certified for fire resistance in mission-critical applications.
• ⚙️ Compatible with Automated Dispensing
  Designed for high-volume production — can be precisely applied in various patterns or shapes.
• 🌱 Environmentally Safe
  Fully RoHS, REACH, and Halogen-Free compliant.

Common Applications:

• Electric Vehicles & Battery Systems
• 5G Base Stations & Telecom Hardware
• Industrial Power Modules & Relays
• LED Drivers & Lighting Systems
• Control Boards & Smart Sensors

Choose a two-component curing thermal putty when you need permanent thermal contact with enhanced mechanical integrity. It’s perfect for applications that demand long-term vibration resistance, fixed placement, and durable performance — particularly in automotive, industrial, and energy systems where thermal and mechanical stresses are high.
