At the Equiplast exhibition in Barcelona, Spain (September 14th – 18th, 2021), Plasmatreat Iberia will focus on solutions for surface treatment with plasma technology in the plastics industry. At booth 3-F22 visitors can see different systems for surface activation and coating. Solving bonding or printing issues on plastics are in the foreground on the company’s booth. The Plasmatreat Iberia team will give insights in plasma technology theoretically and demonstrate practically how a plasma system works.
“The success of adhesive bonding and sealing processes for plastic applications depends largely on the surface properties of the substrate. For highly adhesive bonds of e.g., different polymers, appropriate pretreatment is usually essential”, explains Desiderio Diaz Garcia, Managing Director at Plasmatreat Iberia. “We want to use our participation in Barcelona to present our Openair-Plasma technology and its various advantages to our Spanish customers and interested people.”
Plasma technology based on a simple physical principle: the addition of energy causes states of matter to change. If energy is added to a gas, it is ionized and enters the high-energy plasma state as the fourth state of matter. When plasma with its high energy level comes into contact with materials, the surface properties change e.g., from hydrophobic to hydrophilic. In this way, plasma can be used to specifically change the surface of substrates in order to improve adhesion and even to join together materials that were originally incompatible.
More advantages plasma technology requires are virtually no chemicals, reduces effort, cycle times and costs, and makes long-lasting adhesive bonds possible. For reasons of productivity, cost, and the environment, companies are increasingly abandoning the use of chemical substances or “primers” as bonding agents. Pretreatment with Openair-Plasma from Plasmatreat increases the adhesion and wettability of surfaces, thus enabling the use of more cost-effective material alternatives and new types of material composites while maintaining the quality of the end products.
With a special demo unit, Plasmatreat will show in Barcelona how surface treatment with plasma works by pretreating different polymers. The plasma process is dry, non-contact, selective in location, and fast. The company’s plasma system uses a comprehensive process-control system and is fully robot-compatible and inline-capable. For more specific requirements, functionalized coatings can be applied to the surfaces of materials using the special PlasmaPlus process. With the PlasmaPlus PT-Bond coating process, even plastics that were previously difficult to bond can be bonded directly and permanently with elastic adhesives. Primers that are harmful to the environment and health can be replaced with plasma technology.
To create a bond to adhesives and sealing compounds with plasma, only the part of the material on which the adhesive will be applied is modified. As opposed to primers, this can be controlled with pinpoint accuracy and intensity. This means that, simply by selecting the parameters, a wide variety of materials can be pretreated with a plasma system.
Whether it is structural adhesive bonding of polymers in automobiles, appliances industry, medical and much more - thanks to Openair-Plasma and modern solvent-free adhesives, manufacturing processes can now be carried out entirely without chemical waste. This is equally true for printing and painting. The high surface energy generated by Openair-Plasma ensures optimal bonding.
