Flint Group's portfolio of Anti Set-Off Powders includes two series; Coated and Uncoated. Each series incorporates a variety of grades comprising the respected Varn and Russell-Webb brands.
Our Coated powders are micro-encapsulated with a slip agent which enhances the powder, increasing its hydrophobic properties. They repel water and are attracted to the ink’s surface, giving better ‘set-off’ protection and increased mileage.
Coated powders are quite different in their working properties from the Uncoated powders, but both types perform well in all spray units, and because they resist humidity, they will not clog spray nozzles.
We recommend the application of our Uncoated powders for overprinting, coating and laminating.
