No. The QiangBao® is actually a delivery system for fibers, rubber particles and other sealing agents. As the liquid gets forced out through the puncture, it carries along with it the larger puncture repairing ingredients which pack into and seal the hole, preventing air loss. The green/blue dot that may be visible on the outside of your tire may not harden, but may congeal, which results in a flexible seal.
