Polyurethane

Polyurethane is made of two main chemical components: polymers and urethane. During the chemical process, polymers are linked together by urethane groups, creating a versatile solution that can take many forms. This polymer compound creates a stable, safe and durable product that millions of individuals use every single day. Polyurethanes are versatile, modern and safe. They are used in a wide variety of applications to create all manner of consumer and industrial products that play a crucial role in making our lives more convenient, comfortable and environmentally friendly. The nature of the chemistry allows polyurethanes to be adapted to solve challenging problems, to be molded into unusual shapes and to enhance industrial and consumer products by adding comfort, warmth and convenience to our lives.

Polyurethane is also very useful and important in waterproofing which is what we do best as Clever Polymers. We manufacture polyurethane based liquid waterproofing products that leads us polyurethane coating.

A polyurethane coating is a polyurethane layer applied to the surface of a substrate for the purpose of protecting it. These coatings help protect substrates from various types of defects such as corrosion, weathering, abrasion and other deteriorating processes.

While polyurethane coatings are relatively durable, they are softer and more elastic than their epoxy counterparts. This attribute makes polyurethane-coated floors ideal for moderate to heavy pedestrian traffic. The reduced stiffness gives polyurethane floors a slight springiness, allowing them to absorb sharp impact loading. This durability also makes them more resistant to abrasion and less prone to dents and scratches. Improved elasticity also means that polyurethane floors are able to maintain their shape and mechanical properties in temperatures lower than 30°F (-1°C). Another characteristic of polyurethane coatings is its customizability. These coatings can be formulated to be glossy, muted, opaque or transparent.

The characteristics and properties of polyurethane floor coatings make them ideal for numerous applications, including airports, hospitals, car parks, freezing chambers, malls and other busy commercial areas.

Polyurethane based materials are also used for waterproofing of water tanks. Polyurethane based waterproofing materials used in potable water tanks because of resistant to corrosion, provide durability and harmless to human health. Polyrethane materials are suitable used in wet damp floor areas from internally and externally. In this sense, we can observe that these materials are also used as grouting mastic and filler.

In addition, polyurethane waterproofing materials are used to fill the gaps and cracks formed in the walls or floors of buildings such as tunnels, bridges, concrete wall. Besides, polyurethane based materials used to stop water leaks by reacting with water in the cracks in these structures serve as an injection system. On the other hand, it is possible to observe that polyurethane materials are applied on concrete and cement based surfaces as a floor coating material indoors and outdoors. Polyurethane waterproofing materials – used in roofs, terraces, balconies- can also serve in different fields.

Many polyurethane coatings require no additional processing to cure. They are simply applied and cure upon exposure to moisture in the air. They can be sprayed or rolled onto a base material.

Polyurethane coatings are used for many different applications, including wood floors, metals and on top of other coatings.

Since we are speaking of polyurethane coating, we can point out multiple advantages to using polyurethanes in buildings:

• Buildings last longer and require less maintenance because of the durability of polyurethanes.
• Polyurethane systems are permeable to water vapor, durable and easy to apply.
• When the material is damaged, it can be repaired quickly.
• Polyurethane systems are much more space-efficient, allowing architects and designers to maximize use of internal spaces and are adaptable to different environmental conditions and surfaces.
• Polyurethane systems are particularly versatile and efficient for upgrading older buildings.
• Polyurethane based waterproofing materials fullfil needs in different functions such as membrane, coating, mastic and sealant.

At this point, we can easily reach the result that polyurethane based waterproofing materials are durable, long-lasting and they provide high performance.
