BORON NITRIDE
RELEASE AGENT AND PROTECTIVE COATING

Release Agent and Protective Coating

» Excellent adhesion
» Excellent release agent, especially in applications with non ferrous melts
» Reduction of erosion by the melt and therefore
» Reduced carryover of ferrous contaminants into the melt
» Improvement of ingot surface quality
» Outstanding non-wetability against molten metals
» High thermal conductivity
» Resists build up of dross
CAST-M RELEASE AGENT AND PROTECTIVE COATING FOR THE ALUMINUM INDUSTRY

Cast-M Release Agent And Protective Coating For The Aluminum Industry

» Water-based coating
» Environmentally friendly
» No toxic fumes decomposition products when heated
» Dries easily thanks to the low water content
» The pasty consistency prevents separation and sedimentation of the solid particles during storage.
» Free choice of application technology (e.g. brushing, spraying, dipping)
» No preheating of the casting ladle required
» Coating thicknesses up to 1.5 mm are possible
» Binder permits long lifetime and increases productivity
» No cracking of the coating due to frequent temperature cycles
CAST-G METALLURGICAL PROTECTIVE COATING AND RELEASE AGENT

Cast-G Metallurgical Protective Coating And Release Agent

» This binder permits unparalleled adhesion to the substrate. The type of graphite is immaterial. No particular pretreatment of the substrate is necessary.
» The binder permits coating thick nesses up to 1 mm without the risk of fl aking off. That makes it easy to make local repairs to damaged coatings.
» The coatings can be applied thickly to repair holes and cracks.
» Thixotropy permits the solid particles separating out and sedimenting during storage.
CAST-C RELEASE AGENT AND PROTECTIVE COATING FOR THE ALUMINUM INDUSTRY

Cast-C Release Agent And Protective Coating For The Aluminum Industry

» This binder permits an unparalleled adhesion to all kinds of substrates. It is immaterial whether the substrate is a non-porous cement or a highly porous fi ber material. No particular pretreatment of the substrate is necessary
» The binder permits coating thicknesses upto 1 mm without the risk of flaking off. That makes it easy to make local repairs to damaged coatings.
» The coatings can be applied thickly to repair holes and cracks in the refractory lining. This eliminates the laborious removal of existing boron nitride coatings that would otherwise be needed with refractory materials
» The number of castings per coating can be increased.
» Thixotropy permits the solid particles separating out and sedimenting during storage.
