ALPOLIC metal composite materials (MCM) are some of the most sought-after architectural products because of their quality, versatility and the wide range of finishes. While there are options, choosing the wrong paint system can leave you with a finish that looks muted after just a few years. We often receive inquiries about the types of paint used in manufacturing our MCM, specifically what the differences are between polyester and more expensive fluoropolymer finishes. While they do look similar, at least initially, the variances are more often seen in their performance over time and are clear when reviewing the warranty limitations. Understanding the chemical component of each helps our customers make informed decisions about what is best for their specific projects.
