Strain gauge adhesives
TML adhesives are specially designed for bonding strain gauges to test specimens. Refer to the specification of each gauge series for applicable type of adhesives. To maintain the shelf life, store adhesives in a cool, dry and dark place such as a refrigerator(+5 to +10°C). However, never store in a freezer.
MSDS (Material Safety Data Sheet)
TML supplies an MSDS for all its strain gauge ahesives and coatings. Contact your TML supplier for more information.

Detailed material
CN adhesives(General purpose)
Single-component cement for strain gauges. The time required to bond the gauge is extremely short and handling is very easy. The thin bonding layer allows adhesion to plastic objects as well as metal. Curing time under normal conditions is 20~60 seconds.
