Coating materials

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.

W-1

W-1

The solid W-1 is put into a heating appratus (temperature-regulated oil bath is recommended) and completely melted at 100 to 120°C. The hot melted W-1 is applied over the area to be coated with a brush. The W-1 cools and turns into solid as soon as the application. It is usually applied repeatedly till the cooled W-1 forms an adequate thickness.

N-1

N-1

A layer of N-1 is applied directly from the tube or with a brush over the area to be coated. Curing time is about half a day in room temperature, but it depends on conditions such as the specimen material, temperature, and so on. If the coating layer is too thin, apply another layer to make an adequate thickness.
