Condition of measuring point
The measuring point must be in flawless condition before a sufficiently large cover is spread on it, meaning it is free of dirt, moisture, perspiration from hands, and solder residue. All cable entries must also be very carefully sealed off. In addition, only covering materials recommended by SG manufacturers may be used to protect the SG and adhesive layer.
Commonly used covering materials include:
- a permanently plastic putty with or without diffusion barrier (AK 22 and ABM 75), which is resistant against oil and gasoline,
- air-drying nitrile rubber (NG 150), and
- transparent, solvent-free silicone rubber (SG250) to protect against moisture and water.
Polyurethane lacquer (PU120) is ideally suited for several purposes, including as a primer layer for a multi-coat covering.
