Furnace demolding paint
Dry-film lubricating coating
Also known as: Graphite lubricating paints · Dry film lubricant coatings · Graphite lubricating varnish · Solid lubricant applied as paint
Graphite paints and coatings for release and anti-stick duty in furnaces and thermal fixtures.
[ Technical summary ]
A lubricating paint carries graphite dispersed in a binder that, on curing, fixes the particles to the surface. The result is an adhered, durable film rather than a loose deposit: applied once, it lubricates for an extended period without replenishment. It is the answer for friction points where relubrication is difficult or where grease would attract dust, and it is applied by brush, spray, or dip according to the part.
[ Problem it solves ]
Part sticking, grease residues, and fixture damage in furnace cycles.
Operating conditions
- Application by brush, spray, or immersion
- Film curing
- Dry lubrication
When it is suitable
- The friction point is hard to reach for relubrication
- Grease would attract dust or dirt in that environment
- Lubrication that lasts without periodic maintenance is required
- The part can be prepared and cured before entering service
When it may not be suitable
- The surface cannot be cleaned or prepared before application
- The point requires continuous lubrication to flush contaminants
- The product cannot be validated in the plant before adopting it in production
Process challenges
- Friction in dry contact
- Need for an adherent film
- Temperature or aggressive environment
Advantages
- Adherent film
- Residual lubrication
- Multiple presentations
Limitations
- Not a hydrodynamic oil lubricant
- May stain light-colored surfaces
- Performance depends on surface preparation and reapplication
