The Hernon RotoCoater™ is a non-contact dispensing unit designed to apply sealant or 
adhesive to a bore. The RotoCoater™ consists of an air motor, dispersion cup, and Hernon 
Sureshot™ dispensing valve. The customizable RotoCoater™ dispenser can be used as 
part of a stock dispensing system for a single bore application, or as part of a turn-key, 
complete dispensing solution to apply material to multiple bores simultaneously.
The Hernon RotoCoater™ uses a small, precision air motor to spin a dispersion cup, 
which is inserted into the bore.  The Hernon Sureshot™ valve then delivers a metered 
amount of material to the cup that evenly coats the inner surface of the bore. 
Features
High speed, precise application of sealant or adhesive to bores
No overspray with precise location application
Short cycle times
User Friendly-Easy Cleanup-Low Maintenance
Controlled bead width
Use with a variety of materials
Application in hard-to-reach recesses
The 
dispenser cup prevents overspray and applies a uniform, controlled bead of adhesive. The 
RotoCoater™ system allows for quick cycle times.
The RotoCoater™ can be used with a wide-range of adhesives, sealants, oil, or just about 
any liquid material. It can apply a controlled bead to any size or shape recess, which 
cannot normally be accessed by standard dispense tooling. The RotoCoater™ is user-
friendly and allows easy cleanup and maintenance.

Each RotoCoater™ is assembled with the proper dispensing tube and diameter cup for 
each unique application. A Hernon Sureshot™ valve can also be utilized for precision 
applications. The size of the dispense bead is infinitely alterable and easy to control. 
Complete systems can be designed that apply sealant or adhesive to multiple bores in one 
cycle simultaneously. Please contact a Hernon Representative to discuss your specific 
application.
