Work time and full cure time of most adhesives are calculated at what temperature?

Work time and full cure time of most adhesives are calculated at what temperature?

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

Answer: (B)

Temperature affects how fast an adhesive cures. At warmer temperatures the chemical reaction and evaporation that drive curing happen more quickly, reducing the time you have to position parts (the work time) and making the full cure happen sooner. At cooler temperatures those processes slow down, giving you more work time but a longer overall cure. To provide a consistent, comparable reference, manufacturers specify work time and full cure time at a standard room temperature—seventy degrees Fahrenheit (about 21°C). This gives you a reliable baseline for planning assembly in a typical indoor workshop. If your environment is hotter or cooler than that, expect the times to shift accordingly, so you’d adjust based on actual conditions or consult temperature-compensated data.
