Material Notes:
QSil 58 is a red, high temperature, self-leveling, two-component silicone material primarily used for potting applications. The two applicable catalysts are 0.5% DBT by weight and 10% Deep Section Catalyst by weight. The 0.5% catalyst level can be increased or decreased to obtain desired cure speed. Cure speed can be accelerated by adding DBT catalyst in increments of 0.1% DBT. QSil 58 can be catalyzed with 10% Deep Section Catalyst for application requiring a deeper cure. The material can also be vulcanized at temperatures up to 70°C to increase cure speed.Key Features: Excellent thermal stability Self-leveling Variable cure speedPart of the Amber Chemical Group.
