How Sono-Tek improves the quality of thin film coatings with Plasma and Corona technology

Since 1975, Sono-Tek has been a global leader in ultrasonic coating solutions, offering advanced and patented thin-film coating systems. These systems provide comprehensive solutions to complex and coating challenges ranging from research and development to high-volume production in many industries worldwide. 

The challenge of super thin coatings
One of the biggest challenges Sono-Tek often faced was the adhesion of super thin coatings. “In some cases, it is difficult for our thin coatings to adhere to substrates” explains Chris Cichetti, Vice President at Sono-Tek.

The company found that surface treatment with plasma or corona prior to liquid application solved the adhesion problem.

“The surface treatment allows our ultrasonically atomized spray to wet out better and create uniform thin films. The implementation of the Tantec machine has resulted in higher quality coatings. Some applications would not be possible without a plasma or corona treatment step,” adds a satisfied Chris.

Choosing Tantec as a partner
Sono-Tek was introduced to Tantec almost ten years ago through trade shows in similar industries. After testing a plasma treater in their application lab, Sono-Tek chose to offer Tantec surface treatment system as an upgrade to their automated coating systems. “The performance and reliability of Tantec equipment is top notch. Their sales and service support are also of the highest caliber,” says Chris, who has been with Sono-Tek since 2005.

Decisive factors in the decision-making process
Initially, price was a deciding factor for Sono-Tek, but after a decade of strong and constructive collaboration, Sono-Tek is one of Tantec’s preferred equipment suppliers. “The prices are still extremely reasonable, the quality is excellent, and the support and service has always been outstanding,” says Chris.

Recommendation to other companies
Sono-Tek highly recommends Tantec’s plasma and corona treaters to other companies. “We often recommend Tantec equipment to our customers. They can buy the surface treatment equipment through Sono-Tek, and have it integrated into our solutions, or they can buy it directly from Tantec,” Chris concludes.
