Eccocoat UV 7993, a one component, solventless UV light and moisture cure conformal coating, is now available from Emerson & Cuming. This urethane-based coating offers excellent chemical and moisture resistance, mechanical toughness, and a resilience that minimizes potential component stress. This coating emerges tack-free within 5-7 seconds after UV exposure, and "shadow" cure areas that may not be directly reached by the UV finish cross linking at room temperature. This dual cure system can be applied anywhere from 1 to 40 mils thick.
Eccocoat UV 7993 has been designed for use in high-speed dip, spray and flow conformal coating equipment. Eccocoat UV 7993 is compatible with industry standard solder masks, no-clean fluxes, metallization, components and substrate materials to provide outstanding adhesion and protection to all surfaces.
