Anti-stick coating for construction equipment
Bucket and hopper anti-stick coating
Also known as: Anti-stick coating for buckets · Excavator hopper lubricant · Anti-stick for shovels and tools · Paint to prevent material build-up
Graphite film that reduces material sticking in buckets and hoppers.
[ Technical summary ]
Wet or abrasive material sticks to buckets, hoppers, and tools and forces stops for cleaning. A graphite coating forms a film that reduces that sticking and rubbing wear. It does not remove plant cleaning; it reduces how often material stays stuck. Application method and re-coating are set by the machine cycle.
Each process needs a specific product and application method. ESGRAF selects the solution according to temperature, material, load, cycle, and application method.
[ Problem it solves ]
Reduce material build-up on buckets, hoppers, and tools without a grease that attracts more dirt.
Processes
- Material loading and unloading
- Bucket or hopper coating
Operating conditions
- Contact with soil, aggregate, or ore
- Outdoor operation
When it is suitable
- Material sticks to the bucket or hopper
- Frequent cleaning stops the loading cycle
- Rubbing wear from the material needs reducing
When it may not be suitable
- The machine manufacturer forbids coatings on that surface
- The material must not be contaminated with black residue
- The surface tolerates no black residue and there will be no cleaning stage
Process challenges
- Sticking of wet material
- Abrasive wear of the coating
- Reapplication in the field
Advantages
- Less build-up in bucket and hopper
- Less mess than heavy greases
- Reduces rubbing and surface wear
Limitations
- Does not eliminate plant cleaning
- The coating wears with the abrasive
- May stain the material if contact is intense
