Once an adhesive is applied it will start drying, cooling down, curing.
Setting speed is defined as the time it takes for an adhesive to form a bond, without the need for compression of the bonded materials.
Setting speed is an important requirement for hot melt applications where compression is usually short.
The setting speed of the formulation must be fast enough to keep the materials together and create a bond after the compression stage.
Rule of thumb is; The setting speed of the adhesive should be faster than the machine compression time.
