High-quality coatings have a number of benefits, including glossy finishes, tactile feel, and slip/skid resistance. They can also provide a protective barrier against moisture, oxygen, and grease. But for these coatings to perform properly, they need to be able to adhere tightly to the substrate.
Corona treatment is the ideal solution for increasing the adhesion of coatings to substrates. Many substrates have low surface energy, meaning that coatings cannot easily adhere to the surface, leading to flaking and poor durability. Corona treatment works by exposing the substrate to a high voltage electrical discharge, modifying the substrate and substantially increasing its surface energy.
The increased surface energy from the corona treatment process allows for much better adhesion of a wide variety of coatings, including:
