3M Novec EGC-1720 Electronic Coating is a clear, low viscosity solution of a fluorosilane polymer carried in a hydrofluoroether solvent. This material covalently bonds to glass and metal oxide layers, forming an effective anti-smudge coating on anti-reflective surfaces. As such, the product can be used in a variety of electronics applications, such as anti-reflective (AR) flat panel displays; various electronic
components; pellicles; MEMS; semiconductor chips and components; fiber optics;cellular phone components; and other sensitive materials.

Novec EGC-1720 coating dries to a thin (50-100?) transparent film with excellent anti-wetting, anti-stiction and anti-migration properties. The solvent component is nonflammable, low in toxicity and provides an acceptable environmental profile for today’s demanding electronic applications. The product contains no volatile organic compounds (VOCs).
