BONDERITE L-GP D31A
Known as Pulvegraph D31A
BONDERITE L-GP D31A is an aerosol presentation based
on pure and low friction lamellar graphite, providing heat
resistant and lubricating coatings at temperatures up to
1,000 °C and beyond.
BONDERITE L-GP D31A is a heat resistant varnish which
polymerises at ambient temperature, and has a good
covering power (about 7 m²/spray can).
Benefits :
- BONDERITE L-GP D31A is an aerosol presentation,
indispensable for this type of composition, which
provides lubricating and heat resistant films on any
surface and at any temperature. At ambient
temperature, the coating polymerises within 15 minutes
and, at operating temperatures there is further
hardening of the film which improves its refractory
properties. For example, a 0.3 mg/cm² coating with a 3
μ thickness loses no weight after an exposure during 1/
2 hour at 600 °C or lasts for 3 minutes at 900 °C.
- After a light curing at 100 °C the film becomes
completely insoluble in normal solvents and obtains
maximal resistance to abrasion.
- Generally, all the properties of the film: resistance
against heat, abrasion, washing by any liquid and wear
are improved with increase of surface temperature.
Application :
- BONDERITE L-GP D31A is applied in any case where
release properties have to be improved and the friction
effects reduced in operating temperatures up to 1,000
°C.
- Glasworks:
Coating of the deflectors in bottle production as well as
moulds treatment before use.
- Foundry:
