Nordson Corp.’s Felt Tip/Flow Brush Primer Dispensing System is designed to robotically apply solvents, cleaners and primers to a variety of substrates, delivering consistent film builds and reducing primer waste.

The system can be configured for single-stage applications, including the dispensing of cleaning agents onto plastic or metal substrates, or two-stage applications involving clear and black primers for glass bonding. Cleaning and priming components prior to adhesive application allows for optimal adhesion and promotes long-term durability, the company says.

The standard system consists of a bulk delivery system, one or two applicator tools, a pneumatic valve pack and system controller.  Based on the part type, operators attach either a felt tip or a brush to the outlet of a fluid valve, and then this felt tip or brush acts like an ink marker and applies the primer or cleaner to the substrate in a specified width and thickness.

A variety of felt tips and brush types are available to meet multiple applications and part geometry requirements. The tips are manually slipped onto the outlet of the valve, and an o-ring ensures a leak-free fit.  During downtime, the tip can be stored in a fume that prevents shop air and moisture from reacting with the primer or cleaner, which can lead to curing and hardening.

Offering a user-friendly PLC interface, the system controller monitors and controls the function of both the applicator tool and delivery system. A touch-screen display provides for system setup and adjustments, as well as system status and diagnostic information. Multiple part IDs can be used to establish dispensed volume set points for a variety of part styles.
