Description

Boron-Nitride-Coating Grade HP is a special coating for the superplastic forming of components from titanium for the aerospace industry. It finds application for components even with severe forming ratio. Boron-Nitride-Coating Grade HP is a formulation based on boron nitride, blended with a refractory binder. This environmentally friendly coating contains no solvents and is free from chlorides and fluorides. Boron-Nitride-Coating Grade HP is assigned for the coating of the die surfaces as well as the SPF sheet metals. It is an alternative to solvent-based graphite and boron nitride SPF parting agents. Boron-Nitride-Coating Grade HP results in a very smooth surface like a gloss coating lacquer. It shows good adhesive strength to the sheet metal at ambient temperature as well as within the high temperature area.

Application

• The surfaces to be coated should be clean, dry and free of dust. Degrease SPF sheets prior to application of Boron-Nitride-Coating Grade HP.
• Usually homogenisation of this product is not necessary. However after long storage time the suspension should be well suspended by slight agitation.
• The received consistency can be used for brushing or rolling. Dillution with distilled water is necessary for spraying.
• Spraying is recommended in order to achieve a uniform coating.
• Dry out coating at temperatures with 80 to 100°C (180-210°F) for 1 to 4 hrs.

Storage-Container Size

Containers should be kept closed and product protected against frost. A storage temperature of >5°C (>41°F) is recommended. Boron-Nitride-Coating Grade HP is available in 1kg-containers.

Safety Advices

Boron-Nitride-Coating Grade HP is free of solvents and according to data available to us a non-hazardous preparation. An EC material safety data sheet is available.
