CFCM Biochar 400A recent study found that biochar nanoparticles (BCN), or graphene oxide, derived from spruce wood and wheat straw, can improve corrosion resistance in zinc-rich epoxy coatings. The study, published in Progress in Organic Coatings, suggests a more sustainable option for the coatings industry.

Researchers included Yong Tian from the School of Science of Qingdao University of Technology and Zhenxiao Bi and Gan Cui from the College of Pipeline and Civil Engineering of China University of Petroleum.

Four kinds of coatings were prepared for analysis:

  • Pure zinc-rich coating (0-ZRC);
  • Graphene oxide-based zinc-rich coating (GO-ZRC);
  • Sulfonated multiwall carbon nanotube-based zinc-rich coating (SM-ZRC); and
  • SM-GO-based zinc-rich coating (SG-ZRC).

The coatings were then studied via open circuit potential (OCP), an electrochemical impedance spectroscopy (EIS), a salt spray test, a 3D confocal microscope and an electro scanning electron microscope (SEM). Researchers found that coatings with the presence of GO increased the shielding effect of zinc particles, improving corrosion resistance.

The study also found that biochar increases the interlayer spacing of coatings. GO's galvanic corrosion is relatively weak, and that carbon nanotube should not be used to modify GO in zinc-rich coatings.

Other Biochar Studies

In 2019, researchers at the University of Sheffield, in South Yorkshire, England, had found a use for pine needles beyond holiday decor.

Cynthia Kartey, a Ph.D. student in the university's Department of Chemical and Biological Engineering, argued that different products—including paint—could be made from chemicals extracted when pine needles are processed.

According to Kartey, about 85 percent of pine needles' makeup is a complex polymer known as lignocellulose. The structure is broken down into a solid by-product, biochar and a liquid product, bio-oil, which typically contains glucose, phenol and acetic acid, which can be used for making paint and adhesives.

Researchers said that the ultimate goal would be to use the chemicals to replace less sustainable substances used in the industry.

CFCM TeknaGun 400

Carlisle Fluid Technologies’ DeVilbiss TEKNA spray gun was recently featured on an episode of Detroit Muscle on Power Nation TV to bring a 1973 AMC Javelin back to life. Featuring a high finish quality and operator ergonomics, The TEKNA gun’s high transfer efficiency provides materials savings for solvent or waterbase paints.

The spray gun technology, which has been used in automotive refinishing processes for many years, is designed to spray all types of materials and comes with high efficiency or HVLP air caps that produce large spray patterns with even material distribution.

New Bacharach Sling Psychrometer


CFCM slingpsychrometer 400Paul N. Gardner USA, global distributors, producers, and designers of quality physical and inspection instruments for the paint, coatings, and related industries, has introduced a new offering: The compact, portable Sling Psychrometer.

As an easy way to measure relative humidity levels quickly, this uniquely compact Bacharach Sling Psychrometer accurately determines per cent relative humidity without the necessity of consulting complex tables. There is no need to wet the wick each time a reading is taken, and it contains a slide rule calculator which correlates wet and dry bulb thermometer indications for direct reading of relative humidity. When not in use, the thermometer case telescopes into the handle for protection.

The Sling Psychrometer consists of two thermometers that are turned by vigorously swinging the handle and exposing the thermometers to rapid air movement. These two thermometers are called dry bulb and wet bulb. The bulb of one thermometer is placed in direct contact with the room air to measure dry-bulb air temperature. The bulb of the other thermometer is covered with a silk or muslin sleeve that is kept moist to record the wet bulb temperature. Evaporation cools the wet bulb more than the dry bulb, and the humidity is obtained as a function of change in temperature. The atmospheric humidity is determined by calculations, steam tables, or using a psychrometric chart. Gardco.com
