Coil Coating Comparison Guide

At Sherwin-Williams, we are obsessed with what’s next.

As the industry leader in coating innovation and performance, we’re constantly developing coatings in various technologies to ensure your vision passes the test of time. To help you find the perfect coating for your project, we’ll discuss the basics of what’s in a coating, coating selection considerations and the various products we offer.

What’s in a Coating?

While all liquid coatings consist of pigments, resins, solvents and additives, not all are formulated the same. Any combination of these ingredients can enhance a coating’s performance capabilities, physical properties and costs. Understanding what’s in a coating can help you find the best technology for your project.


Here's a quick overview of what each ingredient in a coating does:

  • Pigments provide color, hiding and chemical resistance
  • Resins bind pigments to the substrate and provide weather resistance properties
  • Solvents help transport the solids to the substrate
  • Additives provide unique properties that enhance the coating’s durability, flexibility, hardness, weatherability and texture to meet product specific needs



Coil Coating Resin Systems

Resins are the backbone of the formula as they hold the entire coating system together. They’re responsible for basic performance capabilities, like resistance to abrasion, scratching, corrosion, moisture and UV light. Resins also give coatings their adhesion, hardness and flexibility.

There are four types of resins that can be used in coatings:

  • Polyester resins give coatings a hard finish, good flexibility and good corrosion resistance, making them ideal for general purpose, interior and exterior metal building components.
  • Siliconized Modified Polyester (SMP) is a polyester resin with silicone added to strengthen weather resistance and gloss retention. Due to its great weathering properties, SMP resins are a great choice for exterior metal building components, roofing and wall panels.
  • 70% Polyvinylidene Difluoride (PVDF) has superior weather performance and UV resistance, making it the best option for exterior building components, walls and roofing, composite panels and curtain walls.
  • Fluoroethylene Vinyl Ether (FEVE) is similar to PVDF in that it has excellent weathering performance and UV resistance. FEVE resins offer exceptional chalk, fade and stain resistance, so these resins work best in coatings that are applied to exterior metal wall panels and composite panels.



Pigments help enhance the overall appearance of coatings with color and special effects. We know how important it is to find a color that matches your vision. That’s why our coatings can be formulated with three different types of pigments to achieve your perfect color.  

  • Inorganic (Ceramic) Pigments are made from complex metal oxides and give coatings an opaque appearance to help hide a substrate or base color
  • Organic Pigments have a higher chroma and wider range of colors compared to inorganic pigments but are less stable in sunlight and heat.

We can help you select the best pigment to meet the unique needs of your project and achieve your desired aesthetic.


When deciding which of our proprietary coatings is right for your next project, there are several factors you should consider. To pair color with the best coating technology, you’ll want to know:

  • End-use application
  • The project’s geographical location
  • Natural elements, weather and sun exposure
  • Desired color
  • Project sustainability requirements
  • Damage resistance

Having this information helps us assess which coating characteristics are the best choice for your project. From there, we can make a recommendation based on your unique needs. Together, we’ll customize a coating that matches your vision.
