Advances in Paint and Coating Manufacturing Equipment

Details of lacquer production
Core paint and coatings manufacturing processes have remained largely unchanged since the dawn of the industry. Ingredients are mixed into a liquid (organic solvent or water), a process that is often followed by milling to achieve the correct particle size for products comprising dispersions. Despite this, the paint and coatings industry is very dynamic. Business trends, market demands, governmental regulations,...

Analytical Series—Microscopy Techniques for Coatings Research: Surface and Depth Characterization of Latex Paint Films

Medical Research Scientist Typing Information Obtained from New Experimental Drug Trial. She Works in a Bright and Modern Laboratory.
Waterborne coatings are multi-component, heterogeneous systems containing a variety of additives, in addition to water, polymer binders, and pigment particles. The distribution of various ingredients in the coating films directly affects a coating’s appearance and performance; for example, optical properties, substrate adhesion, chemical resistance, and mechanical durability. Over the years, a plethora of analytical tools have been utilized in coatings...

Hansen Solubility Parameters (HSP): 2 – Applications

beautiful drip paint close up on white isolated background. drip red paint
In Part 1 (Coatings Tech, May 2018, p.60), I introduced Hansen Solubility Parameters and their theoretical basis. If you have read that article, your first questions probably were how do I find or measure such parameters and how do I use them. Values for solvents and many different polymers may be found in the literature (references 1-4 plus many others)....

Getting Out of The Lab—Advantage of Evaluating Coatings In a Real-World Manufacturing Environment

Industrial 4.0 Cyber Physical Systems concept , Gears , automation robot with abstract background
This article outlines an unmet industry need for formulators to conduct robust testing of their coatings products in real-world or simulated environments that closely resemble an OEM facility’s environmental and processing conditions as coatings are applied and cured. The illustrative examples provided in this article are not hypothetical but are based on actual OEM and end-user processes, widely available coatings...

Hansen Solubility Parameters (HSP): 3—More Applications

bucket of blue paint
Part 1 (CoatingsTech, May 2018, p.60) introduced Hansen Solubility Parameters (HSP) and their theoretical basis. Part 2 (CoatingsTech, July 2018, p.76) was concerned with sources for HSP data along with information on applications. Besides being helpful in designing paint formulations, solubility parameters can be very useful in solving problems. This article presents several examples.

Contact-based Nondestructive Testing (NDT) at Height with Aerial Robotics (Drone)

Ship's Bridge close up against blue sky
To take nondestructive testing (NDT) measurements at height, equipment such as aerial lifts, scaffolding, ladders, or other solutions are required to reach areas on ships, bridges, aboveground storage tanks, flare stacks, and other infrastructure and industrial sites. This is both dangerous, due to the possibility of falls, and time consuming. In certain instances, it may also require taking an asset,...

Balancing Performance of Slip/Mar Additives Using a High Throughput Approach

Luxury modern white kitchen
Additives formulating can be resource intensive and time consuming to paint manufacturers due to the plethora of ingredient combinations and interactions that affect performance properties.  These challenges may inhibit the efficacy of selected additives, which are particularly important in low-VOC formulations to address foam control, water sensitivity, and general surface properties.  Silicone additives in particular are disproportionately influential in impacting...

Understanding Consumer Preferences for Architectural Paints Using the ART™ Device

Understanding Consumer Preferences for Architectural Paints Using the ART™ Device
While paint color can transform the way a room looks, how a paint “feels” is critical to those applying the paint—whether they are professional painters or do-it-yourselfers (DIY). Market research has confirmed this time and again. Manufacturers recognize that the ease or effort of paint application is responsible for the first, and possibly longest lasting, consumer impression and will strongly...
