Gap Filler 1400SL

Features & Benefits

  • Thermal Conductivity: 1.4 W/m-K
  • Self-Leveling
  • Very Soft
  • Vibration Dampening

Description

Gap Filler 1400SL is a two-part, thermally conductive, silicone based, liquid gap filling material. This material has an extremely low viscosity to enable self-leveling and filling of voids resulting in excellent thermal transfer. Unlike cured thermal pad materials, a liquid approach offers infinite thickness variations with little or no stress to the sensitive components during assembly. As cured, Gap Filler 1400SL provides a soft, thermally conductive, form-in-place elastomer that is ideal for fragile assemblies and filling unique and intricate gaps. Gap Filler 1400SL exhibits low level natural tack characteristics and is intended for use in applications where a strong structural bond is not required. Dispensing Due to its low viscosity nature, Gap Filler 1400SL will settle upon storage. Each container must be thoroughly mixed before combining Part A and Part B via static mixer and dispensing into application.

Typical Applications include

  • Automotive electronics
  • Telecommunications
  • Encapsulating semiconductors and magnetic components with heatsink
  • Silicone sensitive applications
  • Lighting
  • Power Supplies
