ZYP Coatings top grade Boron Nitride Spray for use with ceramic and steel fusing and slumping moulds.  This is the best Boron Nitride on the market for glass art. Recommended by Creative Paradise Inc. Excellent for use on moulds for casting and texture where higher temperatures are encountered. ZYP is a separator you can trust on moulds where higher (fusing) temperatures are used, for a smooth, clean release.

Please note that once you have used BN spray on a ceramic mould it is not possible to re-coat with a traditional paintable primer e.g. Primo.  This will outlast traditional powdered primers by a significan margin before re-coating is required, which is easy to do with

Top up coat(s) can be applied as neccessary according to firing temperature and frequency. With a casting mould a top up coating may be required each time due to higher temperatures.  It will allow a clean realease without spines and sharp edges.

Application instructions:

Set up a spray area with newspaper or the like to protect the surroundings, and undertake the job outside or somewhere very well ventillated.  Always wear a respirator mask, gloves (it comes out of the nozzle very cold) and safety glasses. MSDS is attached to your order confirmation email, or call us for your copy.

The first time you use ZYP boron spray it is necessary to apply two coats. Hold the can 10-12 inches from the mould and apply in 2-3 second sweeping bursts.  Hold both the can and the mold upright.  Apply a first, light coat across all the mould, any cavities and texture that will come in contact with glass. For larger moulds you may need to use a longer 3-5 second blast.  Do not saturate the surface.  If it beginst to look wet stop spraying immediately. Allow the mould to dry out and then re-spray the wet area lightly.

Set the mould aside for 5 minutes to dry, then re-apply a second coat as before, then leave to dry for 15 minutes before use. 

Apply one light coat each time you fire. Top up coat(s) can be applied as neccessary according to firing temperature and frequency. With a casting (frit fill) mould a top light up coat will be required each time due to higher temperatures.  It will allow a clean realease without spines and sharp edges.
