Newest generation of circuit board conformal coatings
Article Type: New materials and equipment From: Anti-Corrosion Methods and Materials, Volume 61, Issue 6
New Ecosonic® Conformal Coating powered by Nano-VpCI® represents a technological breakthrough in a new generation of circuit board conformal coatings, combining outstanding moisture intrusion prevention, as well as superior corrosion resistance, with Cortec®’s patented Vapor phase Corrosion Inhibitor technology. It contains an optical identifier visible with ultraviolet light, assuring rapid and effective visual confirmation of proper coating on surfaces.
This high-tech nonconductive coating is designed to extend long-life performance of new and repaired electronic assemblies, especially those which are under adverse corrosion conditions such as high heat, chemicals, salt spray, moisture and atmospheric humidity. More importantly, it saves money by extending product life and reducing labor time.
The acrylic-based, VpCI® coating forms a strong protective barrier against microscopic dendrite growth, termination and surface corrosion, moisture, fungus, dust and other environmental contaminants. It also enhances circuit reliability by prohibiting dangerous conditions such as leakage from high impedance circuits with high component density topography. The coating is VOC-free, fast drying and easily removed with solvents for repair.
Ecosonic® Conformal Coating powered by Nano-VpCI is a single component formulation that is much easier to use than two component coatings eliminating special metering and mixing equipment. It is available in aerosols and bulk liquid.
