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

Tips for Prepainted Metal Maintenance

For most buildings, the exterior is designed to be its most important eye-catching feature. While we’re wired to be extra mindful of the cleanliness and maintenance of the interior of our homes and offices, we sometimes neglect to remember to give the outside of our buildings the proper care. One of the biggest advantages of prepainted metal is its easy maintenance, but there are a few easy steps to make your metal panels shine bright.

Rinse the surface with water.

This sounds like a no-brainer, but this is one of the easiest ways to clean coated metal panels. Dirt and debris built up over time can affect the quality of the panel’s appearance and potentially reduce the lifetime of the coating. Simply rinsing the surface with a garden hose or pressure spray system will clean most buildups on a coating surface, allowing the panels to look brand new.

Clean with soap or water for difficult areas.

Whatever Happened to … Acid Rain?

Air emissions and global warmingThis is the first in a series of posts under the general heading, “Whatever Happened to … ?” The idea is to revisit issues and opportunities of the past and help bring you up to date on what has been accomplished and what is still yet to be done. So … whatever happened to acid rain?

As it pertains to the prepainted metal market, and especially to metal roofing, acid rain became an accepted and understood phenomenon in the late 1970s and early 1980s. Badly corroded roofs were becoming more prevalent, but—like any new problem—it took some time to identify the root cause and to learn how to overcome the issue of red rusting on roofs. And, as with any root cause analysis, an early root cause declaration is usually challenged. Then more research is done, more challenges are raised, and, eventually, consensus is reached.

When “Just Right” Means “Uh-Oh”

nccaA while back, I wrote about the “just right” conditions necessary for the formation of fog. That particular post discussed the scattering of light, which is done by materials such as titanium dioxide (the principal pigment in white paint) and clouds (where water droplets do the scattering). The birds are chirping at sunrise and the vernal equinox has already passed, which means the sun is finally in the Northern Hemisphere and the days are getting longer and warmer—and all of this points to the beginning of another building season. That got me to thinking about a few other “just right” conditions that seem pertinent for this time of year. And, once again, water comes into play. Continue reading

Three Benefits of Prepainted Insulated Metal Panels

insulatedmetalpanelsArchitects and building owners continue to expand the use prepainted metal  for its long-term durability, specifically its excellent  chalk, fade, and adhesion performance. The use of Insulated Metal Panels (IMPs) is also on the rise in a variety of roof and wall applications due to its sustainability and versatility. Combining the two, prepainted IMPs provide  superior energy efficiency and durability, both of which are necessary  in today’s competitive marketplace to comply with ever-evolving building codes and customer expectations.

Prepainted metal is a popular choice for consumers, architects and specifiers who are looking for environmentally friendly, durable, and aesthetically pleasing options. The National Coil Coating Association’s (NCCA) members are seeing a growing trend for textured, prepainted metal products in commercial and residential building design.

While the use of textured paint in coated metal building products is often found in roofing applications for its environmental benefits, the visual and textural innovations of recent years have opened up textured products to a number of applications. Continue reading
