While parylene provides a reliable, versatile conformal coating, it can require removal. When circumstances necessitate removal of liquid coatings – acrylic, epoxy, silicone or urethane – a wide range of chemical solvents can be used to detach the film from the underlying substrate. No single chemical material/process is equally successful for all uses, but solvent processes are employed most frequently because they do the least damage to printed circuit boards (PCBs) and their components. Such is not the case with parylene.Read More

Solvents can be used safely. However, the exposure of the operator to the solvent fumes must be REGULARLY measured and RECORDED. This ensures a safe operating environment and if an OSHA problem does arise in the future, evidence exists to rule out the conformal coating process as the culprit.
