PPG recently announced the launch of its SEMCO sealant removal, mixing and application kit, a portable, wheeled tool kit for the application and removal of aerospace sealants, adhesives and potting compounds on aircraft at any remote site.
The kit consists of a lightweight battery-powered dispensing gun and mixer, along with a spare, rechargeable battery and charging accessories housed in a watertight, crushproof and dustproof case. Users can quickly and easily remove old sealant and apply fresh product without requiring the aircraft to be moved to a hangar.
“This kit provides people working in difficult environments with a simple solution for sealant removal and application,” said AbdulHalim Sayyed, PPG global marketing manager, packaging, Aerospace.

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
