Description
Dielectric inks and coatings play an important role in protecting and enhancing conductive materials. Dielectric coatings create an insulating layer and provide crossover links that make printed silver inks more durable. Coatings are solvent-resistant to humidity, temperature and solvents.
111-27 is a flexible, electrically insulating coating suitable for application by spraying, dipping and syringe dispensing. This product features excellent adhesion to Kapton, Mylar, glass, and a variety of other surfaces. Unlike conventional insulating materials, this product is very resistant to flexing and creasing. Some applications for 111-27 include, but are not limited to, insulating polyimide flexible circuits, polymer thick film circuitry, and membrane switches. 111-27 also protects components from moisture, salts, and abrasion.
