CHT QSil 550LV A/C Low-Viscosity Potting Silicone

Description

QSil 550LV A/C is a two part, addition cure silicone potting compound engineered for electronic encapsulation applications requiring excellent flow and deep cavity penetration. With a very low viscosity of 1,300 cps per component and a long gel time of 110 minutes at 25 C, QSil 550LV is ideal for potting complex assemblies, tight tolerances, and components sensitive to shear or heat.

This 100 percent solids system cures to a hard, low modulus elastomer that provides thermal conductivity, electrical insulation, and long term stability across a wide temperature range. QSil 550LV is UL 94 V 0 rated and is available in cartridges, quart kits, gallon kits, pails, and drums to support both manual and automated dispensing.
