To understand whether polyurethane enamel is water-based, we must first clarify the two main types of polyurethane coatings: solvent-based and water-based. The difference between these two coatings lies mainly in the solvents they use, that is, the main volatile medium in the coating.

The formula design of the epoxy primer determines its original viscosity. If the product has a high viscosity when it leaves the factory, direct use may cause difficulty in brushing or spraying. At this time, adding an appropriate amount of diluent can reduce the viscosity and improve construction performance.

Marine paint is extremely wear-resistant and weather-resistant, and can withstand multiple tests in the marine environment, such as wind and wave impact, ultraviolet radiation, and temperature changes. Ordinary paints have relatively weak wear resistance and weather resistance and are mainly used for surface protection and decoration indoors and in non-extreme environments.

As early as the 1950s, some states and cities in the United States began to realize the hazards of lead paint and took preliminary restrictive measures. For example, Chicago and New York City began to restrict the use of lead paint in residences in the late 1950s. However, these measures had limited impact nationwide.

The anti-rust effect of zinc-rich primer mainly depends on the electrochemical protection principle. Zinc, as an active metal, has a lower electrode potential than iron. When zinc-rich primer is applied to the surface of steel, zinc powder forms an anode in the coating, and steel becomes the cathode.

Epoxy primer is an important part of the anti-corrosion coating system for aluminum products, especially suitable for use in severely corrosive environments. It has excellent adhesion and chemical resistance, and can form a hard protective film on the surface of aluminum to block the intrusion of moisture, oxygen and other corrosive substances.

Liquid rubber paint can form a continuous, seamless coating during construction. This seamless design can eliminate the potential leakage risks caused by the presence of seams in traditional roof coatings.

Generally speaking, white road marking paint lasts about 2 to 4 weeks on grass. This time range varies depending on a variety of factors, including grass type, climate conditions, grass maintenance, and frequency of use.

There are significant differences in performance requirements between traffic paint and conventional paint. Traffic paint needs to cope with complex road environments and must have high wear resistance, weather resistance, fast drying and good adhesion. Ordinary paints are mainly used for interior and exterior walls of buildings, furniture and decorations, and their performance requirements are relatively low.

Commonly used protective paint coatings: 1. Epoxy resin paint, 2. Polyurethane paint, 3. Alkyd resin paint, 4. Acrylic paint, 5. Chlorinated rubber paint, 6. Zinc powder paint, 7. Silicate paint.
