Light management is also important. High-energy light such as ultraviolet rays can destroy the chemical bonds of curing agent molecules and trigger photolysis reactions.

As a supporting additive, paint thinner, through its scientifically designed formulation, plays a key role in spray painting. It not only quickly and evenly thins the topcoat to the optimal application viscosity.

When mixing paint hardener with the main agent, if a special stirrer is not used or the stirring time is insufficient, the paint hardener may be unevenly dispersed in some areas, forming "unreacted areas".

On porous or highly absorbent substrates, the excellent sealing properties of paint primer are crucial to the success of the final coating.

Paint hardener does allow paint to reach its working strength faster after application. This effect is due to the chemical reaction characteristics between the hardener and the paint components.

When paint thinner is fully mixed with paint, it will gradually penetrate into the molecular structure of the paint and reduce the viscosity of the paint.
