Description
For routine experimental stress analysis applications under temperate environmental conditions, M-Bond 200 adhesive is ordinarily the best choice. This adhesive is very easy to handle, and cures almost instantly to produce an essentially creep-free, fatigue-resistant bond, with elongation capabilities of five percent or more.

M-Bond 200 Kit

M-Bond 200 is a special cyanoacrylate which has been pretested and certified for use in bonding strain gages. It is an excellent general-purpose adhesive for laboratory and short-term field applications. The procedures are described in detail in Micro-Measurements Instruction Bulletin B-127 , a copy of which accompanies each kit of adhesive.

The user should note that the performance of the adhesive can be degraded by the effects of time, humidity conditions, elevated temperature, and moisture absorption. Because of the latter effect, strain gage installations should always be covered with a suitable protective coating. When necessitated by more rigorous test requirements and/or environmental conditions, consideration should be given to one of the epoxy adhesives.

Cure Requirements
One-minute thumb pressure, followed by a minimum two-minute delay before tape removal. Bond strength increases rapidly during first five minutes. Cure time must be extended under conditions of low temperatures [<70°F (<21°C)] or low humidity (<40% RH).

Operating Temperature Range
Short Term: -300°to +200°F (-185°to +95°C)
Long Term: -25°to +150°F (-32°to +65°C)

Elongation Capabilities
>5% at +75°F (+24°C), [3% at +75°F (+24°C) when used with CEA-Series or EA-Series / Option E strain gages].

Shelf Life *
3 months at +75°F (+24°C) after opening, with cap replaced immediately after each use. Note: To ensure a proper seal, wipe bottle spout clean and dry before replacing cap.

May be stored unopened up to 3 months at +75°F (+24°C) or 6 mo at +40°F (+5°C). Note: Condensation rapidly degrades adhesive performance and shelf life; after refrigeration, allow adhesive to reach room-temperature before opening. Refrigeration after opening is not recommended.
