First we need to look at the amount of B glue (curing agent). Generally speaking, the more B glue, the faster it dries. In addition, it is related to temperature, the higher the temperature, the faster it dries, such as AB mass ratio 3:1, 25℃ can be able to do a day, if you want to accelerate curing, you can cover the hot water in the mold.

When the curing agent of epoxy resin is not changed, the curing speed can be slowed down by adding lipids (dibutyl phthalate), ketones (acetone) and other substances; In addition, the curing speed of epoxy resin adhesive can be slowed down by selecting polyamide curing agent and polyether amine curing agent.

The correct adhesion method can also accelerate solidification:
1. At room temperature (25℃), the adhesive will be treated and cleaned, and then the A glue and B glue will be overlaps with the visual 1:1 ratio, or A glue will be applied to one adhesive part, and B glue will be applied to the other adhesive part, and then glued together, and 2-5 times before and after running in the fixed 5-10 points.

2, at room temperature (25 ° C) will be treated by adhesive clean, and then A glue and B glue with a 1:1 ratio of plastic coating sheet after mixing, within 3 minutes on the surface to be bonded, fixed 5-10 minutes can be positioned.

3. The adhesive can reach 50% of the highest strength after 30 minutes and reach the highest strength after 24 hours. It can be used in the environment of -60℃-100℃.
