Plast-aid sticks things together in two different ways, a Chemical Bond and Mechanical Bond.
Why is that important? Material that chemically bonds can join very smooth surfaces. While a mechanical bond must be rough to work.
Plast-aid does not dry. When the powder and the liquid are mixed together it starts a chemical reaction that takes about 15 minutes to complete.
Yes. Plast-aid heating up is the last part of the chemical reaction. Once it starts cooling back down, Plast-aid's cure is complete.
