USA • The Minnesota-based Cortec Corporation has developed a static dissipative corrosion inhibiting paper that serves as a complete packaging paper for valuable electrical and electronic items.
Cortec’s new EcoSonic ESD Paper eliminates static electricity build up through the use of an environmentally friendly coating made from soybean oil and coated on the surface of the paper.
Cortec states that the paper performs better on the static half-life test (a test with an environment consisting of little or no humidity) than papers with conventional anti-stat coatings consisting of alkyl ammonium chlorides, typical ethoxylated amines, typical imidazolines, phosphated esters, and nonionic based antistat coatings. The antistat protection from EcoSonic ESD Paper is thermally stable at high temperatures (in excess of 392°F (200°C) and pH stable between 2 and 11 at temperatures in excess of 100°F (38°C) for several days. EcoSonic’s ESD Paper conforms to performance specifications for MIL-PRF-81705D (Static Decay Rate and Surface Resistivity).
Made from high quality neutral natural kraft paper without using chlorine or other bleaching,Cortec claims that the new ESD Paper will also provide contact, vapor, and barrier phase corrosion inhibition for ferrous and non-ferrous metals. It conforms to the requirements of performance specification MIL-PRF-3420H (vapor inhibiting ability) and is effective against aggressive environments including humidity, SO2, H2S, and galvanic corrosion from dissimilar metals. At the same time, it is free of nitrites, phosphates, silicates, and other hazardous compounds and is non-toxic, biodegradable, and fully recyclable/repulpable.
The EcoSonic ESD Paper can be used to protect any material capable of being damaged by electrostatic discharge such as:
- Printed circuit boards (PCBs)
- PCB components
- Integrated circuits
- Telecommunications equipment
- Electrical panels
- Electrical enclosures
The new paper eliminates the need for chemicals, specific concentrate calculations, holding tanks and special application systems. One must only use adhesive tape as needed to hold paper folds in place. The paper does not influence physical properties of even the most sensitive electrical components, including conductivity and resistance. Parts protected in the EcoSonic ESD Paper can be painted, welded, and soldered. The paper can also be used for electrostatic dissipation and corrosion protection during electronics assembly.
