What is polyurethane paint? – Its properties, advantages and types

Polyurethane paint is one of the highest quality coating paints with very high resistance in contact with acid rain. Also, one of the properties of this paint is its high durability against the sun and its quick drying. This color shows unique mechanical and chemical properties due to the absence of orange skin. Polyurethane is one of the polymer and industrial paints and it is used to cover different surfaces. is bought and Polyurethane sold for use in various cases such as covering iron fences, mechanical equipment, cabinets, hospitals, etc. In this article of Jahan Shimi Physik, we study polyurethane paint and its properties.

What is the color of polyurethane?

Polyurethane paint is one of the industrial paints for covering the bottom layer on different levels. These surfaces are protected by said paint against corrosion, wear, weathering and other destructive factors. For this reason, this color is used on surfaces that are in the open space. The structure of polyurethane paint is a polymer that has hydroxyl and isocyanate groups.

One of the properties of this compound is heat hardening and thermosetting because it hardens and does not take shape in front of heat. One of its other properties is being thermoplastic, which means it melts and forms against heat. If the polyurethane formulation changes, it becomes glossy, matte and transparent. Being soft and durable and having elasticity is one of the physical characteristics of the mentioned color. For this reason, this combination is used in floors to be resistant to impact.

Advantages

Polyurethane is sold in various domestic and foreign companies and you can buy an authentic product. This product is used in many cases. There are several benefits to using polyurethane paint, some of which we mention here.

One of the advantages of using this paint is its quick drying, which saves time. This color is easily applied on the surface.

Another advantage of polyurethane paint is its high resistance to water and chemical compounds. The oil base of this paint has made it highly resistant to steam and moisture. Water-based urethane paints are not suitable for wet and outdoor environments.

In addition to the beautiful and attractive appearance of this type of paint, which is matte and shiny, it creates a hard and strong layer after drying. As a result of the formation of this layer, the underlying surfaces are protected from wear, scratches and other damages.

The important advantage of the color in question is resistance to ultraviolet rays and harsh environmental conditions. This color also has high thermal stability.

Polyurethane paints

Matte polyurethane is an example of this color that does not have a gloss but maintains the natural appearance of wood. Polished polyurethane is another example with low or medium gloss and it covers dirt and scratches. The last type is glossy and semi-gloss polyurethane, which has a lot of reflection and shine.

There are two types of urethane paint, water-based and oil-based.

Water-based polyurethane paint has a slight odor but a transparent appearance. It dries quickly and is recommended for cases that are more exposed to heat and different weather conditions. When using this color, it should be noted that more layers of this color are applied to the surfaces.

This oil-based paint turns amber over time and has a very pungent smell. But it takes longer to dry compared to water-based urethane paint. Due to the high resistance of this color to heat, in kitchen tables. it can be used
