• contains "white graphite"

Desription

ALU-STOP LC21 Boron-Nitride-Coating is special coating for the non-ferrous metal casting and is produced using boron nitride of highest quality. Thus ALU-STOP LC21 Boron-Nitride-Coating shows a very good non-wetting behaviour against Al, Mg, Zn and Pb as well as their alloys. It is an ideal high temperature release and lubrication agent for the coating of ladles, troughs, distribution troughs, moulds and protects these efficiently against attacks by aggressive melts.

Application

• Resuspend coating prior to use and dilute with distilled water if necessary.
• Application on clean surfaces is possible by painting or spraying. Best results may be achieved by spraying onto warm surfaces (50-150°C, 122-302°F).
• Dry thoroughly. Do not contact wet coatings with metal melts. Additional layers may be applied after drying.
• Best performance of ALU-STOP LC21 Boron-Nitride-Coating is achieved by thin coatings (up to 50-150µm). Thick coatings may crack during use.
• Do not damage coating during use because damaged areas are not sufficiently protected.
• Tools may be cleaned with water.

Storage-Container Size

ALU-STOP LC21 Boron-Nitride-Coating must be protected against frost. A storage temperature of >5°C (>41°F) is recommended. The containers should be kept closed. ALU-STOP LC21 Boron-Nitride-Coating is available in 6kg-containers.

Safety Advices

ALU-STOP LC21 Boron-Nitride-Coating contains water and is free of solvents. According to data available to us ALU-STOP LC21 Boron-Nitride-Coating is a non-hazardous preparation. An EC material safety data sheet is available.
