The Beginner's Guide To Advanced Sensors Strain Gage Installation

Micro-Measurements Certified M-Bond 200 is an excellent general-purpose laboratory adhesive because of its fast room-temperature cure and ease of application. When properly handled and used with the appropriate strain gage, M-Bond 200 can be used for high-elongation tests in excess of 50,000 microstrain (µε) , for fatigue studies, and for one-cycle proof tests up to +200 °F [+95 °C] or down to -300 °F [-185°C]. The normal operating temperature range is -25° to +150°F [-30° to +65°C]. M-Bond 200 is compatible with all Micro-Measurements Advanced Sensors Technology strain gages and most common structural materials. When bonding to plastics, we recommend testing a small sample area to ensure compatibility. For best reliability, it should be applied to surfaces between the temperatures of +70° and +85°F [+20° to +30°C], and in a relative humidity environment of 30% to 65%.

M-Bond 200 catalyst has been specially formulated to control the reactivity rate of this adhesive. The catalyst should be used sparingly for best results. Excessive catalyst can contribute many problems; e.g., poor bond strength, age-embrittlement of the adhesive, poor glueline thickness control, extended solvent evaporation time requirements, etc.

Since M-Bond 200 bonds are weakened by exposure to high humidity, adequate protective coatings are essential. This adhesive will gradually become harder and more brittle with time, particularly if exposed to elevated temperatures. For these reasons, M-Bond 200 is not generally recommended for installations exceeding one or two years. (Typically not more than one year).
For proper results, the procedures and techniques presented here should be used with qualified Micro-Measurements installation accessory products. Those used in this procedure are:
• CSM Degreaser or GC-6 Isopropyl Alcohol
• Silicon Carbide Paper
• M-Prep Conditioner A
• M-Prep Neutralizer 5A
• GSP-1 Gauze Sponges
• CSP-1 Cotton Applicators
• PCT Gage Installation Tape

SHELF AND STORAGE LIFE
M-Bond 200 adhesive has a minimum pot life of three months at +75°F [+24°C] (not to exceed the date of expiration) after opening and with the cap placed back onto the bottle immediately after each use.
Note: To ensure the cap provides a proper seal, the bottle spout should be wiped clean and dry before replacing the cap.
Unopened M-Bond 200 adhesive may be stored up to nine months at +75°F [+24°C] or twelve months at +40°F [+5°C].
Note: Condensation will rapidly degrade adhesive performance and shelf life; after refrigeration the adhesive must be allowed to reach room temperature before opening, and refrigeration after opening is not recommended.

HANDLING PRECAUTIONS
M-Bond 200 is a modified alkyl cyanoacrylate compound. Immediate bonding of eye, skin or mouth may result upon contact. Causes irritation. The user is cautioned to: (1) avoid contact with skin; (2) avoid prolonged or repeated breathing of vapors; and (3) use with adequate ventilation. For additional health and safety information, consult the Safety Data Sheet, which is available upon request.
