processing

1
clean substrate
Bonding surfaces must be clean, dry, and free of grease. For thermally conductive applications, degrease surfaces particularly thoroughly.
2
Apply
Apply with a brush, spatula or paste gun — using thermally conductive pastes, apply thinly and evenly (excess layer thickness reduces heat conduction).
3
Dilute optionally
For thin layers: Dilute the paste in aliphatic or chlorinated solvents. For standard applications, use undiluted.
4
Distribute / Press
When applying heat, join components with a defined contact force — allow excess paste to escape.
5
Curing / Use
Pastes generally remain non-crosslinking and can be used immediately. Do not exceed typical temperatures of 250 °C under thermal stress.
