Momentive SnapSil TN3085 is a one-component, thermally conductive, low volatile siloxane, silicone adhesive that cures at room temperature upon exposure to atmospheric moisture. It cures to form an elastic, flame retardant silicone rubber and exhibits primerless adhesion to many substrates.
FEATURES:
- Fast tack-free time
- Flame retardant (UL94 V-0, File Number E56745)
- Low volatility
- Non-corrosive to most metals
- Primerless adhesion to many substrates
- Low odor cure: releases an alcohol vapor during cure
- Thermally conductive
APPLICATION:
- Bonding in power supplies
- Thermal adhesive between electronic components and heat sinks
- Securing PCBs to substrates
