Have you ever wondered why road paints are always visible and do not wear even after so many vehicles move on them? The answer is simple: road paints are made with different kinds of material and chemical properties so that they are not affected by harsh environments or the vehicles moving on them.
Road paint (สี ทา ถนน, which is the term in Thai) plays a crucial role in maintaining traffic safety. It serves as a visual guide for drivers, pedestrians, cyclists, etc. It provides information about traffic lanes, turning points and potential hazards ahead on the road. Let us explore different types of road paints commonly used for marking routes, highways and other surfaces.
Thermoplastic Road Paint
Thermoplastic road paint is a popular choice for road makers. It helps in having durable and long-lasting road markings. The thermoplastic road paint consists of synthetic resin, glass beads and pigments with other additives. When we heat it, it transforms into a liquid state. In the liquid form, they apply it on the road. It forms a solid, highly reflective and resilient marking when it cools down.
Waterborne Road Paint
As the name suggests, we get waterborne road paint from the water-soluble formula. It is an environmentally friendly option with low volatile organic compounds. It is one of the road paints that is easy to apply and dry quickly. Waterborne road paint is the best choice for making temporary markings on the road.
Cold Plastic Road Paint
This road paint is a two-component system. It consists of a binder and hardener. This type of paint is typically pre-mixed in the factory and then applied to the road surface. Once cured, it forms a durable, wear-resistant, and highly reflective marking. Cold plastic road paint offers excellent adhesion even in places that are damp or in low-temperature conditions.
Epoxy Road Paint
It is known for exceptional durability and chemical resistance. It forms by combining epoxy resin pigments and other additives. Epoxy paint forms a tough and durable coating on the road surface, providing long-lasting marking even in harsh weather conditions.
Chlorinated Rubber Road Paint
It is a specialised type of paint designed for exceptional resistance to chemicals, oils, and fuels. It is commonly used in industrial areas, parking lots and airports where exposure to chemicals is prevalent. Chlorinated rubber paint offers good adhesion to various surfaces and is known for its quick-drying properties.
All types of road paints have different applications. Therefore before using any colour, consider your application purpose.
