Why this article?
Anyone who works in production, maintenance, or process engineering is familiar with the problem: the lubricant must be right—otherwise, there is a risk of downtime, expensive rework, and dissatisfied customers. Here you can find out how to make the best choice, which parameters are crucial, and which Bonderite products from our portfolio are ideal for your application.
How to find the right lubricant
The wrong lubricant can slow down processes, shorten tool life, and increase scrap. Before you decide, clarify the following:
- Temperature range: Start, operation, peak load.
- Friction and load situation: Do you need solid lubricants such as graphite or PTFE?
- Consistency & viscosity: NLGI for greases, ISO VG for oils.
- Conductive or insulating? Particularly important in electrical applications.
- Residue behavior & wetting: Especially crucial in casting.
- Material compatibility: metals, plastics, elastomers.
- Standards & approvals: e.g., NSF H1, internal factory regulations.
Application matrix – quick recommendations
Application | recommendation | Why? |
|---|---|---|
Hot/semi-hot forging | Graphite dispersion or dry lubricating film | Protection against wear, uniform layer formation, tool protection |
Die casting/mold | Release and lubricating agents with or without graphite | Clean mold filling, fewer adhesions |
low-pressure casting | High-coverage graphite dispersion | Stable separating layer, wear protection |
Assembly/disassembly | Anti-seize / high-pressure paste | Prevents seizing, defines tightening torques |
Electrical/Moisture | Dielectric silicone grease | Protection against moisture and leakage currents |

Application & dosing technology – for maximum efficiency
- Manual: Brush, spray, pressure cup – apply evenly, observe preheating temperature.
- Automated: Optimize spray lances, timing, and nozzle pattern; stir dispersions.
- Ensure quality: document pressure, time, flow, and temperature.
Storage & quality preservation
- Store in a cool, dry place, tightly closed.
- Follow the FIFO principle.
- Homogenize dispersions before use.
- Check pastes for consistency and oil separation.
Avoid common mistakes
- Do not use insulating greases on live contacts.
- Incorrect consistency leads to squeezing or assembly problems.
- Do not underestimate residue behavior—it can lead to rejects.
- Processing dispersions without stirring results in inhomogeneous layers.
