THERMAL CONDUCTIVITY THEORY
LCF200 Two-component Gap Filler
LCF series liquid gap filler is a two-component pre-formed thermal conductive material, which can react and cure under normal temperature or high temperature conditions to form soft and excellent thermal conductivity elastomer.
Features & Benefits:
l High thermal conductivity, low thermal resistance, excellent wettability
l Low pressure to electronic components
l Manageable raw material stock ,lower composite cost
l For vehicle electronic products
l Can fill any uneven gaps
l Automatic point dispensing available, any thickness or size available
l High reliability, thermal conductive gel is equal to thermal conductive silicon pad after curing, no volatility.
Unlike adhesive glue, thermal conductive gel has weak adhesion
Typical Applications:
l Communication equipment
l Power equipment
l Medical instrument
l New energy vehicle
l Filling any gap between friable component
and shell

Packing instructions: two types: manual operation type and dispensing type packaging. 1.Manual operation type is generally divided into
50ML AB hose packaging (A/B each 25ML), suitable for one-hand operation; The dispensing gap filler packed in 400ML AB hose, it can also be
packed with A 10KG/barrel and B 10KG/barrel according to the dispenser.
Application process: Dispensing :Syringe match up mixed needle, starting from A contacts B in the mixing head, the gel will change as below:
after 5 minutes will appear higher viscosity, dry out in 10 minutes, the product will gradually, hardening but also be flexible within 3 hours,
showing as hardness rises to no longer change.
