What You Should Know About Plasma Treated Surfaces eight interesting facts about plasma treatment that address why they are used, how they are used, and more.
#1 Plasma: The 4th state of matter.
Everyone is familiar with the three states of matter (solid, liquid, gas), but the fourth state is one that is less well known- plasma energy. Yet, everyone is familiar with lightning seen on a summer evening. This powerful energy is plasma! Essentially, plasma is an ionized gas consisting of approximately equal numbers of positively and negatively charged particles. There are two general forms of plasma: high-temperature plasmas that are found in stars and in fusion reactors; and low-temperature versions used in surface treatment, neon and fluorescent lighting, plasma TVs and semiconductor manufacturing.
#2 Plasma surface treatment is powerful enough to break hydrogen bonds.
Plasma surface treatment is created by combining reactive gas molecules and an electric field. This method uses one or more high voltage electrodes which charge the surrounding blown gas molecules, resulting in a highly ionized field that is forced onto the targeted surface. This highly ionized air stream creates a thermal property that reacts with the substrate and breaks the existing hydrogen bonds by introducing oxygen which recreates the chemical properties of the surface. The plasma process causes a molecular reaction on the substrate. It also creates finely etched and micro-cleaned surfaces resulting in better wettability, stronger bonding traits. See a video of PlasmaDyne Pro treating bottles in a trial here.
#3 Plasma surface treatment improves adhesion.
Plasma surface treatment modifies the surface of a material on a molecular level, enabling it to bond more readily with adhesives, ink, paint, and other media. It is effective on a variety of materials; even difficult-to-bond materials can achieve better adhesion without experiencing surface damage.
#4 Plasma treatment improves adhesion on a wide variety of materials.
Bonding problems are pervasive throughout manufacturing, especially the plastics industry. Manufacturing and decoration often include joining plastic-to-plastic, plastic-to-metal, plastic-to-composite and more. But, plastics and many other materials possess low surface energy or “wettability” and therefore, require plasma pretreatment.
Plasma treatment is a non-invasive, non-heat-based process that can be used on virtually any material. It encourages molecular bonding on surfaces, micro-cleans contaminants, and causes fine etching. Plasma treatment facilitates the bonding of adhesive, ink, paint, and other media to a range of substrates. These materials benefit from plasma treatment:
- Rubber and Elastomers
- Engineering Polymers
- Metals and alloys
#5 Many industries rely on plasma surface treatment for their products.
Plasma surface treatment is used to enhance the wettability, adhesion, and cleanliness of materials within numerous industries, including:
- Aerospace: The aerospace industry uses plasma surface treatment on critical surfaces to enhance adhesive bonding.
- Automotive and Transport: The automotive and transportation industries utilize plasma treatment to improve adhesive bonding between components and enhance paint and coating adhesion to a variety of substrates.
- Consumer Goods: Plasma treatments enhance the functional and aesthetic quality of various consumer goods.
- Electronics: Plasma treatments protect sensitive components within potting. Plasma treatment is nearly potential-free allowing plastics with embedded circuitry to be safely surface treated.
- Medical and Biotech: Plasma treatment is used for raising surface energy and micro-cleaning surfaces to ensure optimal bonding between components and devices.
- Packaging: Packaging materials, such as plastic films, cardboard, and plastics, are often plasma treated to promote adhesive and ink application during printing and labeling operations.
- Printing: Printing operations integrate plasma treatments to enhance surface wettability to ensure precise, vivid, and long-lasting ink adhesion.
#6 Plasma surface treatment is versatile.
Due to its exceptional versatility, plasma treatment has become critical for a wide range of applications, such as:
- Painting, coating, and printing for plastic products
- Enhancing coating adhesion for polymer extrusions
- Printing, painting, and coating rubber profiles
- Cleaning the surface of aluminum and other metals
- Improving adhesion of glue on cardboard products
- Treating silicone foam to enhance adhesive application
- Improving adhesion of paint and ink to composite materials
#7 The advantages of plasma treatment include speed, cost-efficiency, eco-friendliness, and more.
Plasma treatment offers a number of advantages over other treatment options. For example:
- It is potential-free: Atmospheric plasma is potential-free, so the treatment process can be used in conductive, semi-conductive, and non-conductive applications.
- It is effective for surface cleaning: Plasma can be used for micro-cleaning operations, which removes surface impurities and contaminants.
- It is environmentally friendly: Plasma cleans and enhances material surfaces without the use of harmful chemicals or ozone emission.
- It is cost-efficient: Plasma treatment reduces process time by improving bonding, increasing surface cleanliness and wettability. You spend less time processing the substrate and use less ink, paint, glue, or coating due to optimal adhesion. Less waste and scrap are created, plus our plasma systems have low energy costs.
