History of Parylene Technology


The unique Parylene polymer series was isolated by a research chemist in the late 1940s at the University of Manchester in England. Union Carbide Corporation scientist William Gorham later developed a deposition process to apply the film, and Union Carbide commercialized the material and process. Para Tech Coating, purchased licensing for this coating process in 1968, and subsequently developed and patented several important enhancements that optimize performance, consistency and reliability of Parylene vacuum deposition coating.


What is Parylene Coating?

Parylene has become the protective coating of choice for challenging electronics, aerospace and medical applications. Conformal coatings are generally liquid in nature, while Parylene is formed on surfaces from a high purity powder known as a dimer with no liquid stage. The resulting film is thin and conformal, has no pinholes, and resists the effects of organic solvents, inorganic reagents and acids. Parylene serves multiple purposes including electrical insulation, moisture and chemical isolation, mechanical protection, enhanced lubricity, and surface consolidation to avert flaking or dusting.
