Conformal coatings are suitable for rubber, metals, and plastics

. Pinhole-free coatings provide protection from biofluids, chemicals, and airborne contaminants, and they inhibit moisture absorption. The coatings eliminate the risk of stress fractures because the coatings are distributed evenly at room temperature. Produced by Parylene Coating Services Inc. (Katy, TX; 800/397-7650), coatings can be deposited on rubber, metal, plastic, and elastomer surfaces. The company provides on-site coating machinery and technical support, and can produce both low- and high-volume runs of cores, PCBs, silicone rubber, mandrels, and stents. Parylene also offers its PCS dimer to provide a pure coating layer with less contaminates and extractables. Customers can shorten waiting times in obtaining FDA approval with a drug master-file number and a device master-file number provided by the company.
