Features:

Very good conformability

Good thermal properties and will perform over a wide variety of temperature conditions (-60° to 225°F or -54° to 106°C). It has been used at higher temperatures for shorter duration

Electrically and thermally conductive

Can be die-cut into specific shapes

Elevated lead levels in water may result from long term submersion of this product

Best results are obtained when applied to a clean dry surface above 32°F (0°C). Also, by “feathering” the edges – rubbing the tape down with a smooth-edged plastic piece (or similar object) – the tape can be made to better conform to the substrate. This is especially important if the tape is to be used as a “thief” in electroplating where the edges must fully contact the metal base.

Applications:

Electroplating

Radiation barrier

Moisture barrier

Chemical milling

X-ray plate masking

Maskant during paint stripping

Add weight (balance) to equipment parts
