Description

QSil 220 is a two-part, clear, liquid silicone which will cure at elevated temperatures. It has a low viscosity which allows for ease of flow around complex parts, providing electrical insulation and shock resistance. The chemical composition provides hydrolytic and reversion resistance. This material also has excellent, primerless adhesion to most substrates.

KEY FEATURES:
• Convenient 10:1 mixing ratio for use in automatic dispensing equipment or hand mixing
• Contains no solvents Non-yellowing catalyst system
• Heat cure to obtain full properties and adhesion
• UL 94 HB listed, control number: QMFZ2.E205830
