Spray Coating Solutions For EMI Shielding, RFI Shielding, & ESD Shielding


Mueller Corporation offers vapor deposited coatings and conductive spray coatings that can provide a variety of solutions including; EMI shielding (Electro Magnetic Interference Shielding), RFI shielding (Radio Frequency Interference Shielding), ESD shielding (Electro Static Discharge Shielding), heat shielding, vapor barriers, and conductive paths. We utilize two different types of PVD processes; thermal evaporation Vacuum Metalizing and PVD Sputtering. We have proprietary thermal evaporation vacuum metalizing systems that can achieve thicknesses of over 25 microns of aluminum. Multi-layer vacuum coatings can be used to apply Copper/Stainless Steel, Cooper/Chrome, Copper/NiChrome and other combinations to meet your unique shielding requirements

Flexible and Cost Effective Options

Vacuum Metalizing and Conductive painting have their advantages, which is why we offer both Vacuum metalizing and PVD does not accumulate inordinately large build-ups or deposits; the deposition layer is typically .5-5 microns thick. The thickness uniformity, while more consistent, is less important because it will not create fitment issues. Vacuum metalizing has a lower cost per part due to the expense of the material being applied vs. the cost of conductive paints.
Conductive Paint does not have the part size limitations that vacuum metalizing which is based on the size of the vacuum chamber. While metalizing is very durable on its own, clear coats can be applied for added abrasion and chemical resistance. If you need ultimate protection, and the surface of the parts must stay conductive, painting is the only solution available.
Mueller Corporation has a variety of pretreatment processes to both the metalized and painted coatings have excellent adhesion ensuring there is no peeling and flaking.

Functional Spray Coatings

In addition to conductive painting, we also cover other types of functional coats such as; Teflon and Ceramics which offer; corrosion protection, abrasion resistance, chemical resistance, electrical insulation, and low coefficient of friction.
