Choosing a Resin-Based Coating

When it comes to coatings, the resin, or “binder,” acts as an adhesive that keeps all the elements of a paint formulation together. The resin selected is the backbone of the coating and therefore the primary source for determining the coating’s durability and physical properties. When choosing a resin-based coating, it’s important to know some of their key features.

Fluoropolymer resins are known for non-stick properties and their ability to avoid UV damage. The most well-known best performing resin in this category is Polyvinylidene Fluoride (PVDF). PVDF is at least 70 percent of the binder used in superior performance coatings, while an acrylic resin makes up the other 30 percent. PVDFs are found in coil coatings, where exceptional durability is desired. When compared to other coatings, PVDF resin-based coatings were the only coatings that did not lose their original gloss within 2-5 years.

One of the most common causes of failure for resin-based coatings is the risk of color fading. Continue reading


Factors Influencing the Long-Term Performance of Prepainted Metal Buildings

Most metal buildings are made with prepainted metal building panels. The coil coating process used to make prepainted metal provides many benefits, including superior bonding of paint to metal, durability, environmental friendliness, etc. As a result of the use of prepainted metal, metal buildings are aesthetically pleasing, durable, long-lasting, and economically-efficient structures.

The long-term performance of metal building panels and metal buildings is influenced by three principal factors:

  • Choice of materials
  • Environment in which the products are placed
  • Variability of processescropped-header-980x2759.jpg
