What is the change rule of composite strength of solvent-free adhesive? How long does it take to reach the maximum composite strength?
The results show that the solvent-free composite strength changes with time from the beginning of adhesive mixing to the maximum strength and then slowly decays
1) Opening period
2) Rapid curing stage
3) Slow curing stage
4) Stable stage
5) There are several stages, such as slow attenuation stage.
In general, the composite strength curve of different brands of glue is also different. Generally, it can reach 70-80% of the maximum intensity within 72 hours, and reach the maximum intensity in 7-15 days.
