Chapter 13 – Polyurethane Blends for Powder Clear Coatings
FOCUS Tikkurila to build factory in Russia Tikkurila has finalized a Letter of Intent to acquire a 7 ha industrial site at the Greenstate Industrial Park near St Petersburg, Russia. The company will build a new 30 M L/y greenfield facility at the site in 2018, in order to meet the increasing domestic demand. The new plant could be expanded in the future. The new site will house a Research, Development and Innovation (RDI) unit, as well as extensive warehouse premises for raw materials and finished goods with railway connection, which will boost the efficiency of the company’s distribution units. Tikkurila will spend about EUR 30–35 M for the project. The plant design will begin soon and construction work is expected to start in late 2018. Operations at the new site, which will manufacture industrial and decorative products, will begin in 2020.

TECHNOLOGY Chapter 13 – Polyurethane Blends for Powder Clear Coatings This chapter discusses current development trends in the area of polyurethane powder clear coatings, including new contributions related to the use of various diisocyanates, blocked polyisocyanates, resins, and additives. The chapter also shows the relationship between properties of cured coatings and chemical structure of raw materials, and describes important technological parameters of raw materials in the manufacturing process of powder coatings such as functional groups content, glass transition temperature, melting point, and melt viscosity. Systems of the greatest commercial importance are characterized in terms of their chemical composition and applications. Special attention has been paid to ecological and economical aspects of powder systems.

Liquid-Impregnated Surface Coatings Lubricant-impregnated surfaces, generally referred to as liquid-impregnated surfaces (LIS), are slippery surfaces that effectively eliminate the no-slip boundary condition, allowing viscous liquids, gels and emulsions to slide freely. Their superior nonwetting behavior and self-cleaning properties make LIS coatings attractive as a slippery surface

for a wide variety of applications, including consumer packaged goods, agrochemical, oil and gas, manufacturing, medical, pharmaceutical, energy and utilities. In addition, LIS coatings can provide significant sustainable benefits. They can reduce waste, increase product yields, improve production efficiency, provide consistent dosage and enable product innovation. A recent LiquiGlide survey confirmed that LIS coatings have the potential to address consumers’ concerns for waste. For example, 100 million gallons of lost product and billions of dollars of associated waste costs per year occur within processing tanks for the paint manufacturing industry alone. LIS coatings are currently being applied to these paint manufacturing tanks to recover these costs through the reduction of yield loss, waste water and cleaning time. Additionally, while there have been recent advances to incorporate “smart” functionality into traditional paint and coatings, many of these properties are already inherent to LIS coatings. However, these traditional coatings rely on infusing chemical functionality or texture into the existing dry films to produce the desired “smart” functional effects. Selfhealing coatings depend on the release of chemical payloads from microcapsules upon coating damage, while self-cleaning coatings usually depend on nanotechnology approaches to texture hydrophobic films or superhydrophobic chemistry to generate their nonwetting properties. By contrast, LIS coatings directly incorporate slippery functionality into the liquid layer of the coating. LIS coatings are self-healing due to the mobile liquid layer that spreads throughout the textured or porous solid. LIS coatings are also selfcleaning because of their extremely low contact angle hysteresis and ability to repel a wide variety of liquids. In addition, LIS coatings can incorporate functionality to tune product sliding speeds via appropriate selection of liquid viscosity, coating thickness and underlying solid texture. LIS coatings are distinctly different than alternative slippery coatings, such as superhydrophobic surfaces or excess liquid approaches, because LIS coatings can maintain their slipperiness over time. Abrasion reduces the slipperiness of these superhydrophobic coatings through mechanical degradation of the delicate nanoscale and microscale features that support these air pockets. Thus, superhydrophobic coatings have limited durability because they depend on stable airliquid interfaces to maintain their slipperiness. LIS coatings have untapped potential because they can be applied to a wide variety of industries to advance sustainability by reducing waste, increasing product yields, improving production efficiency, providing consistent dosage and enabling product innovation. LIS coatings can be used for moving viscous liquids through a pipe, on an external surface, from a tank or dispensing from a package. Moreover, LIS coatings are
COATINGS durable and can be formulated to maintain their slipperiness over the product’s lifetime. And while the LIS coating design parameters are complicated, they are reducible to commercial applications, such as those discussed for the coatings industry, which should continue to shift from dry film formation coatings to long-lasting wet surfaces.

Custom-Designed Powder Coat Line to Increase Efficiency at OMT-Veyhl USA The installation of a new, one-of-a-kind automated powder coat line will improve productivity and efficiency at the OMT-Veyhl USA manufacturing unit. OMT-Veyhl USA, Holland, Michigan, produces workspace components. The new line will triple the output of painted parts per day. The powder coat (PC) line was custom designed for OMT-Veyhl USA by its engineers. Every part of this PC line has been carefully engineered to reach its fullest potential of efficiency and environmental friendliness. Energy is consistently saved or renewed while allowing for minimal waste throughout the powder coating process. One of the many advantages of the new PC line is its ability to reuse heat from the ovens to heat the facility. Not only does it reuse heat, but it reuses the water from the product wash. It does this by filtering the water through special oil filters that separate the water and oil. The water can be reused in the wash and the oil will be recycled for other uses. Lastly, the new PC offers light curtains the parts pass through before entering the powder booths. These curtains inform the powder guns where the parts are on the rack, which allows the powder guns to only spray powder in that area, reducing the amount of powder and energy used.
