AppliedProduct selection and comparison are drawn from the owner-authorized Coating Additives Handbook. Verify current TDS/SDS and performance in the intended formulation before use.
Technical challenge
Electrostatic spraying may require a controlled liquid-conductivity window, while film properties must be evaluated separately.
Product selection
Candidates are organized by a supplied technical handbook and the individual published TDS where available. These are starting points for trials, not confirmed equivalents or universal dosage recommendations. Grades without a SITI TDS page are not treated as formally published product profiles.
| Grade / evidence | Relevant system | Selection considerations |
|---|---|---|
| KOBOND 9124Handbook grade; TDS page unavailable · handbook slide 116Products category ↗ | Liquid coating conductivity adjustment for electrostatic spraying | Handbook quaternary-ammonium candidate; measure liquid resistance under actual equipment settings. |
| KOBOND 9129Handbook grade; TDS page unavailable · handbook slide 116Products category ↗ | Conductivity adjustment in selected coating systems | Handbook carboxylate candidate; compare compatibility, appearance and conductivity. |
Conductivity-adjustment technology comparison
The table reproduces product-selection directions from the owner-authorized handbook. Listed grades are screening candidates, not interchangeable products or a claim that every grade has a published SITI TDS. Confirm current documentation and the complete formulation.
| Type | Handbook-listed grades | Selection consideration |
|---|---|---|
| Quaternary ammonium | KOBOND-9124, 9110 | Handbook describes effective liquid-coating resistance reduction; measure in the actual electrostatic process. |
| Carboxylate | KOBOND-9129, 9114 | Conductivity adjustment with compatibility in selected systems; check coating appearance. |

Conductivity in application
The handbook discusses additives used to reduce electrical resistance and adjust conductivity of liquid coatings. In electrostatic spraying, an appropriate liquid conductivity range may improve charging and spray stability for a particular equipment setup. Too much or too little conductivity can affect application, so the target must come from the coating, equipment and process requirements rather than a universal number.
Chemical families and compatibility
Quaternary-ammonium and carboxylate-type additives are among the families described. Their effect on electrical properties and formulation stability can differ with solvent or water content, binder chemistry and other ionic ingredients. Evaluate the selected material in the full formulation. Do not assume that a measured change in liquid-coating conductivity proves a durable antistatic property of the cured film.
Trial design
Measure conductivity or resistance using a defined method and temperature. Compare spray behavior under the actual equipment settings, then separately inspect the cured film's appearance, adhesion and other required properties. If the end use specifies static dissipation after cure, establish that with its own method and conditioning. The source handbook does not establish a universal target or certification.
Formulation guidance
- Specify whether the requirement concerns liquid application or the cured film.
- Record the measurement method, temperature and formulation composition.
- Verify spray behavior and cured-film properties separately.
Troubleshooting
- Charging or spray stability varies
- Measure liquid resistance with a defined method and temperature under the actual equipment settings.
- Film appearance changes after additive dosing
- Recheck binder compatibility and cured-film properties; liquid conductivity does not establish end-use antistatic performance.
