What you need to know about reflective paint
What is reflective paint?
Reflective paint serves more than one purpose. It’s not just a bright color. What exactly makes the paint “reflective”? Let’s take a look at the components.
Ingredients and Composition
Paints consist of a base that can be either water- or solvent-based. Then, a series of reflective materials, such as microspheres and nanoparticles, are added. Ceramic or aluminum are standard materials. Glass bead is also popular. These reflective materials are chosen based on their application and level of reflection.
Light Reflective Technology: How it Works
This is where the magic happens. The reflective paint material scattering light causes retroreflection. The reflective paint particles reflect light when they hit a surface coated with the material. They do not absorb or disperse the light.
Imagine it like a small mirror. Lab tests confirm that this is an important attribute that can reduce heat by up to 20 percent compared to metal surfaces not treated.
There are many types of reflective paints for metal.
Water-Based
Water-based Based Reflective Paints have low volatile organic compounds. These paints are less toxic and more accessible to clean than solvent-based ones. They may be less durable than other options, but technological advancements have made them more robust and suitable for indoor or outdoor use. These are an excellent choice for projects requiring quick drying times.
Solvent-Based
Solvent Paints are known to be durable and resistant to environmental factors such as moisture and UV Rays. Due to their higher VOC levels and more complicated cleanup, these paints can be more challenging. Their resilience makes them perfect for industrial applications, where extreme conditions play a role.
Epoxy-Based
Epoxy Resistant Paints have a high level of adhesion and chemical resistance. These paints are durable and hard-wearing, which makes them perfect for heavy-duty industrial applications. They can be expensive and require professional application because of their complex curing processes.
Acrylic-Based
Acrylic-based reflective paints are an excellent choice for those who want a mix of durability and ease of application. They adhere to various surfaces, including metals, and offer a durable finish that resists flaking or chipping. You can use acrylic-based paints in automotive and aerospace applications where adhesion and flexibility are essential.
Oil-Based
Oil Based Reflective Paints have a high gloss finish and are smooth. These paints are highly durable but have a long drying time. People opt for these paints when they want a high-gloss, luxurious finish. However, they are rare in industrial settings due to their longer drying time and higher VOC content.
