Electronic devices have undergone a revolution in size, performance and portability. From consumer devices like smartphones, tablets and wearables to specialized industrial technology such as automation controls, electronics are everywhere — including in many challenging environments. Without adequate electronic protection, components inside devices can suffer corrosion when exposed to contaminants. This degrades electronic performance and may lead to electrical shorts and device failure. At the same time, smaller, more complex, dense printed circuit boards (PCBs) with high-performance components, LEDs and a variety of miniaturized components are placing higher demands on electronic protection coatings.
3M™ Novec™ Electronic Grade Coatings offer protection against corrosion for the sensitive internal components of devices and are ultra-thin compared with traditional conformal coatings. Our products are the result of decades of experience improving electronic grade coatings to help guard against moisture, water/salt water immersion, sulfur, oils, humidity and pollution. These offer ease of application, reworkability and the ability to apply without masking or curing.
When you choose Novec coatings, you gain all the advantages of 3M’s innovative materials, deep knowledge base and dedicated support. Here’s a look at some of the key benefits of these high-performance coatings:
Novec electronic grade coatings have been proven effective against corrosion through extensive testing, as seen in these images showing untreated and treated circuitry that has been exposed to salt fog. They provide a uniform oleophobic and hydrophobic layer that helps cover surfaces of a component for exceptional repellency of moisture, oils, dirt, grime, fingerprints and other environmental contaminants. Count on Novec coatings to help provide excellent protection against corrosive agents that devices might encounter, including:
Ultra-thin Novec coatings can be alternatives to traditional conformal coatings and a smart choice for your business. In a dip application, thicknesses can range from 0.1 to 1.3 microns, or 1 to 6 microns. In a typical single-pass spray, thicknesses range from 1 to 6 microns; layers can be built up to create appropriate thicknesses. This compares to up to 25 microns or more for typical conformal coatings. Thinness has several advantages, including:
3M Novec Electronic Grade Coatings can save costs and increase efficiency without compromising performance.
Performance without compromise means choosing products that don’t put workers or the environment at risk. Novec electronic grade coatings are formulated with 3M™ Novec™ Engineered Fluids, which offer:

MAN: Today's consumers expect their mobile devices to work flawlessly in the most challenging environments. These increasingly sophisticated electronics are highly susceptible to environmental contaminants such as moisture, sulfur, pollution, and grime. Without proper protection, sensitive electronic components can quickly corrode, often leading to electrical shorts, poor performance, and device failure.

Note how moisture beads up and sheets off the side of the circuit board with the Novec coating. Novec Electronic Grade Coatings can help provide protection and repellency for the most delicate materials. To demonstrate this, let's take a look at how an ordinary tissue reacts when submerged in water. The hand pulls a tissue out of a box. ON SCREEN TEXT: Ordinary Tissue Paper The tissue is delicately dunked into a container of water. ON SCREEN TEXT: Ordinary Tissue Paper Submerged in Water The hand attempts to pick it back up, but parts of the tissue paper break off. The drenched tissue clumps together as it dangles above the water. MAN: It absorbs the water and breaks down. Now, let's take the same ordinary tissue and dip it in Novec Electronic Grade Coating. The hand plucks another tissue out of the box. ON SCREEN TEXT: Ordinary Tissue Paper Using an extended pair of tweezers, the tissue is submerged in a container filled with the coating. They swirl the tissue in the container as text appears around it.

MAN: After a quick dry, the coated tissue can be submerged in water and remains repellent, sturdy, and intact. The gloved hand pushes the tissue into the water, but it does not fully submerge itself or absorb any liquid. Beads of water drip off the soft surface and back into the container.
