One is physical drying:
Paint reinforcing agents can promote the rapid drying of paint and shorten the drying time.
One is chemical curing:
The curing agent reacts with the main paint in combination, which can increase the hardness, brightness and adhesion of the paint film, and improve the chemical stability and anti-corrosion ability of the paint. It can make the paint film full and delicate, smooth and elastic, wear-resistant and not easy to scratch.

It is written on the packaging of the paint!
