HarperScientific launches UV Re-Leez

HarperScientific, the printing and coating supplies division of global anilox supplier Harper Corporation of America, has developed UV Re-Leez, a product formulated especially for removing UV ink from narrow web presses, anilox rolls and all equipment, with on-press use in mind.

‘We were thrilled to get reports from customers that they found great success using UV Re-Leez as a solvent ink cleaner for anilox and gravure cylinders in ultrasonic tanks,’ said Jim Doedderlein, technical sales specialist for HarperScientific. ‘We’ve had reports that customers are cleaning press sleeves in ultrasonic tanks and cleaning the between-station dryer assemblies the same way. In a case where the air diverters on the drum side of the dryer were clogged with ink, the customer used UV Re-Leez in the ultrasonic tank to clean them, and the operator called to tell us the dryers looked like new!’

‘Another converter ran its ultrasonic tank with UV Re-Leez to clean chrome/copper gravure cylinders, and said it was the best stuff they have seen,’ said Jim Harper, vice president at HarperScientific.

As a result of the reports, HarperScientific conducted its own corrosion and efficacy tests on UV Re-Leez that indicated the product is indeed, safe and effective for ultrasonic tank use. A one-week soak test found that UV Re-Leez is non-corrosive for aluminum.

‘We talked to ultrasonic tank manufacturers who indicated that until now there has not been an ultrasonic cleaner that is aluminum-safe,’ said Tony Donato, Harper Corporation process & product development engineer. ‘In addition, a gravure user told us that cleaning a roll covered with cold seal adhesive with their former cleaning solution in the ultrasonic tank gave off a very foul odor that filled the whole plant. But UV Re-Leez cleans the cold seal roll without any noxious smell.’

For best results, mix UV Re-Leez with water at a ratio of one part cleaner to four parts water, and run the ultrasonic tank without heat. Without the heater, the ultrasonic vibration heats the cleaner to about 120 degrees Fahrenheit – a temperature that brings excellent results.

The new cleaner’s advanced surfactant technology is exceedingly environmentally friendly, using no petroleum distillates or environmentally hazardous chemicals. It is a biodegradable, low-vapor pressure and low-V.O.C. cleaner.

Available exclusively through HarperScientific, this super-concentrated formula, which can be diluted with water, is sold in 4-packs of 32 oz. bottles, pails and drums.
