ESD protective paper doubles up as corrosion inhibitor

January 03, 2017 // By Julien Happich
Cortec Corporation has developed a static dissipative corrosion inhibiting paper that serves as a complete packaging paper for valuable electrical and electronic items. Sensitive electronic metal items can be wrapped in EcoSonic ESD Paper to be protected from damaging static electricity buildup and corrosion.

The EcoSonic ESD Paper eliminates static electricity buildup through the use of an environmentally friendly coating made from soybean oil and coated on the surface of the paper. 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 this paper is thermally stable at high temperatures in excess of 200ºC and pH stable between 2 and 11 at temperatures in excess of 38ºC for several days. The novel packaging material 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.
