When one thinks of ancient structures, the image of an old aqueduct (stone held together with cement) might come to mind.Continue reading
The old saying, “As exciting as watching paint dry” could not be further from the truth when it comes to coil coatings. First, the paint that is applied to a metal coil during the coil coating process dries (bakes, really) in just 15 to 30 seconds. A lot takes place in that short period of time: 1) the solvents evaporate (they are captured and destroyed in this environmentally friendly process), 2) the coating flows to produce a smooth surface, and 3) a chemical reaction takes place to create a cured, hard, scratch-resistant yet flexible coating. To the chemists who create this magic, it’s exciting stuff, but it’s difficult for the consumer to appreciate since the process takes place in a factory setting. What consumers can appreciate is what they see when the product reaches the marketplace. So … let’s see what’s innovative these days!
First, let’s talk about beetles. Yes, beetles. Especially the ones that have that cool iridescence. They create that effect by … well, it’s complicated!Continue reading
A nationwide study by Berkeley Lab details benefits of lighter-colored, solar-reflective walls
As you likely know, NCCA members and their customers along the prepainted metal value chain have been supporters of “cool roofs” for 20 years. Without question, this technology effectively reduces energy consumption during the hot months of the year. So, what’s next?
“Cool walls”! Wait, what? Cool walls? Cool-roof technology is intuitive; roofs face the sun, but walls are vertical structures. How much solar energy can they possibly be exposed to? Well, you’ve come to the right place to find the answer.[i]Continue reading
If you are a manufacturer or designer, there are five common myths about coil coating or prepainted metal you might have heard. We’re going to bust those myths one by one and show you why prepainted metals are your best choice. Here are the facts.
Myth 1: Prepainted metal is expensive.
The truth is, utilizing prepainted metal saves you money by eliminating the costs associated with an in-house paint shop. When you post-paint, you have the added expense of labor, materials, scrap, and inventory. Plus, there are numerous costs (and headaches) when you’re dealing with EPA and OSHA compliance. It can cost big bucks to make sure you’re properly handling waste, emissions, and cleanups. In addition, storing paint in your facility can cost you in higher insurance premiums. To determine whether prepaint is for you, download the cost analysis form under Education on the NCCA website.Continue reading
Prepainted metal is all around us. You are probably familiar with its many uses in the building and construction and appliance markets, but you may not be aware that prepainted metal is also important in the transportation sector.
Think “transportation,” and your mind typically leaps to cars and trucks—and from there to the beautiful body panels that are an aesthetically important part of these vehicles. Spoiler alert: Painted automotive body panels require specialized coatings and application techniques and, as a result, are not ideally suited to the use of prepainted metal. Nonetheless, there are plenty examples of coil-processed material used in the transportation sector.Continue reading
Urban legends are, well, false—but still fun, because there is always something believable about them. Is it true that you are never more than six feet away from a spider? Who really knows, and some might say who really cares? But let’s face it—don’t you find yourself wondering, “Hmmm, I wonder if it’s true, and should I be calling an exterminator?” Well, here’s something that is not a legend: You would be surprised to learn how many articles in your home, just feet away from you, are made from prepainted metal.Continue reading
We’ll confine our discussion here to obvious weather differences, but we won’t get into how coil coatings formulators accommodate those differences. That’s a discussion for another day. Just know that steel and aluminum companies, pretreatment suppliers, and coatings chemists are working hard to formulate a coil coating system that provides the necessary performance for a particular region.Continue reading
Sustainability, upcycling, downcycling, landfills … the list goes on! What is one to think when every material is touted as sustainable? Don’t believe me? Visit any material website; for example, cement/concrete, vinyl plastic, wood building products. What is one to make of all these claims—are they real? How does our industry fit in?Continue reading
We begin with two strange words, which in some ways are opposites—and in other ways are similar.
Welcome to the fascinating world of wetting.
First, let’s keep this simple. Let’s only think about water—as opposed to oily materials—that is deposited onto coatings, windows, mirrors, the leaves of plants, etc. The water (in the form of rain, steam, fog, etc.) may form droplets on the surface, or it may spread into a thin film. A hydrophobic substrate causes the water to form droplets; a hydrophilic coating, however, causes the water to spread into a thin film. But how do you keep these two terms straight, given that they sound so similar? Continue reading
I know you had a 30-year warranty, but—after 15 years—those shingles simply must be replaced. Anyone can call a roofer, but why not take a shot at making your own shingles? But first you need a formulation—the recipe—and I’ve got just the one for you. And while we’re at it, let’s compare shingle manufacturing to metal roofing manufacturing.
