Henkel’s has launched Bonderite E-CO Guard and E-CO Guard+ to manage cleaners, rinses, and treatment stages in pretreatment lines.
The company says the goal is process stability, as operators can maintain key process parameters more precisely, reduce manual intervention, and diagnose issues quickly. In this way, the Bonderite E-CO Guard system supports repeatable surface quality and efficient line operation.
The Bonderite E-CO Guard+ module of the E-CO Guard portfolio provides expanded data extraction and flexible control options for metal treatment systems. It enables consistent process performance, reduces manual effort, and integrates into existing operations — supporting both productivity and sustainability goals. Henkel says this addition represents a significant upgrade over earlier systems. It is engineered for easier use, offers additional functionality and expandability, and supports a wide range of requirements across North American metal finishing applications.
In operation, the focus is on continuously stabilizing relevant process parameters. In pretreatment, consistent bath conditions are critical for repeatability and process reliability. Bonderite E-CO Guard+ emphasizes consistent control to reduce variability and avoid large, reactive corrections. Typical measurement variables in North American applications include pH, conductivity, temperature, and ORP; you can also integrate additional signals. The unit features eight individually configurable sensing and control loops, enabling a single line to manage different pretreatment stages and requirements. A key benefit is reduced manual interaction. Automation reduces the need for operator adjustments and helps minimize the risk of inconsistent results or unnecessary chemical additions. Comprehensive diagnostic capabilities can also reduce downtime by enabling faster root-cause identification and quicker corrective action.
For day-to-day metal-finishing operations, integration into existing infrastructure is also essential. Bonderite E-CO Guard+ supports Ethernet connectivity and Modbus TCP for connection to existing PLC or SCADA systems. A USB port complements data access by allowing process data and configurations to be exported for documentation and analysis. A full-color touchscreen provides operator functions and monitoring with on-screen graphing. The chemical-resistant polycarbonate enclosure meets NEMA 4X requirements and is designed for industrial environments.
Henkel will have product information at booth S15034 at FABTECH 2026, October 21-23, at the Las Vegas Convention Center.
