PPG is providing a retroreflective powder coating to Lyft to make the company’s e-bikes—used in its DIVVY bike-share program in the US—more visible while the cyclists travel at night. PPG’s Envirocron LUM technology is designed to reflect maximum light back to the source. Inspired by the reflective properties of deer’s eyes, the single-layer coating refracts light and retroreflects it directly back to a vehicle’s driver to enhance visibility, using a formulation with embedded glass beads.
The coating delivers a non-solvent solution with high transfer efficiency. It provides exceptional scratch and mar resistance for the e-bikes to withstand a high volume of riders and meet Lyft’s goal for a durable and sustainable solution.
Lyft’s pilot program for its new high-visibility e-bikes debuted in the Bay Area in California in June 2021 and expanded to Chicago, Ill, in December. It launched in New York City earlier this year.
The new fleet of e-bikes are coated with an Abel Gray finish, which is a tribute to the late Abel Lopez, a Lyft engineer that was struck and killed by a vehicle while riding his bicycle in October 2020.

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.

Paul 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
