The type of coating required and the application method differ depending on the environment in which the strain gauge is to be used. In general, if one type of coating is not sufficient, multiple coatings can be combined to protect the strain gauges. At TML, the coating applied directly to the surface of the strain gauge is referred to sequentiallyas the first coating, with subsequent coating layers referred to sequentially as the second coating, third coating, etc. Multi-layer coatings are recommended for strain gauge protection.
SDS (Safety Data Sheet)
TML supplies SDS for all its strain gauge adhesives and coatings. Contact your TML supplier for more information.
Coatings in special substances
For use in special substances such as acids, alkalis and alcohols, contact TML or local representatives.
