Factors Affecting the Drying of Antiviral Water-based Paint

The drying environment is an important factor affecting the drying process of antiviral water-based paint.

The higher the temperature and the lower the humidity, the faster the drying speed. Just as clothes can dry quickly and completely in summer, they usually take a long time to dry in winter. Similarly, water-based paint volatilizes moisture rapidly at high temperatures and dries slowly at low temperatures.

The flow speed of air over the paint film surface also matters: in a windy environment, the paint film can dry faster.

Most commonly used drying auxiliary equipment are equipped with exhaust functions, but excessive air velocity will adversely affect the paint film, especially for thick coatings, which may crack or peel off. Therefore, when using air flow to accelerate paint film drying, exhaust ventilation is recommended instead of direct blowing.

The influence of antiviral water-based paint film thickness on drying speed is obvious.

Increased thickness not only leads to more moisture to volatilize but also blocks the passage of water vapor from the lower layer, resulting in a non-linear increase in surface drying time. A thicker film also raises the risk of many film defects, such as film imperfections. Thus, for paint films requiring higher thickness, applying multiple thin coats is a reasonable approach.
