Adhesive work time and full cure time are calculated at which temperature?

Adhesive work time and full cure time are calculated at which temperature?

• A. 68 degrees Fahrenheit
• B. 70 degrees Fahrenheit
• C. 72 degrees Fahrenheit
• D. 75 degrees Fahrenheit

Answer: (B)

The main idea is that adhesive work time and full cure time are defined at a standard room temperature so technicians have a consistent reference. 70 degrees Fahrenheit is used as that reference point because it represents typical shop conditions and provides a common baseline found on product data sheets. At this temperature, you know how long you have to work with the adhesive (open or work time) and how long before full strength is achieved (cure time). Temperature changes affect these times: warmer conditions speed up curing and reduce open time, while cooler conditions slow both. So using 70°F gives a reliable, widely applicable standard for planning and estimating adhesive application in real-world settings.
