On the composition of conformal coatings

On the composition of conformal coatings

Electronic protective coatings, commonly known as "three-proof coatings," are critical materials that ensure the stable operation of electronic components and devices in harsh environments such as humidity, salt spray, and mold. The quality of their protective performance largely depends on the rational selection and scientific formulation of raw materials. The following analysis will focus on the raw material system from the perspective of its main components.

Various types of conformal coatings

Various types of conformal coatings

Electronic protective coatings, often referred to as "three-proof coatings," are specialized coatings designed specifically to protect circuit boards and their components from environmental hazards. Traditionally, these coatings emphasized three key functions: moisture resistance, salt-spray resistance, and mold prevention. However, today’s products have expanded their performance to address a broader range of protection needs. Such coatings can be categorized based on their chemical composition, curing conditions, and solvent types.
