When it is desired to make your paint from a powder-mix, NovaMix provides a general-utility paintable ceramic coating by only having to “JUST ADD WATER” on site; this way, we don’t ship water – which is a concern to some.
PERFORMANCE INFORMATION:
There is indication that NovaMix, made as a liquid-paint, can perform well as a general-utility paintable ceramic coating. The liquid coating made with NovaMix has a relatively low Boron Nitride content – yet still enough to give the non-reactive/ releasecoating characteristics that are desired for many applications. However, please note that … since the NovaMix is a very economical coating, it should not be expected to have comparable performance with the higher-loaded Boron Nitride coatings.
ADVANTAGES:
• VERY ECONOMICAL … Shipped as powder, thus avoiding shipping ‘water
• Easily made into paint by the user
• Provides a protective, relatively nonwetting, ceramic-based releasecoating on all substrates
• Nonstick/nonreactive coating for contacting molten glass
• Easily applied after making into liquid-paint: use like housepaint
• Only requires adding water, sitting, and then stirring to make a good-performing ceramic paint
• Blue, for easy visibility
• This special ‘dry mix’ powder allows easy transformation into a ceramic paint that is usable to very-high-temperatures [i.e., up to 1000 C or 1800 F in air atmospheres] by simply adding water.
POWDER-TO-PAINT: To make 4 gallons of liquid paint
• Empty a 1-kg [2.2 pounds] plastic bag of NovaMix powder into a 5-gal. pail
• Fill up to the FOUR-gallon level with water -- adding the water added over the powder to reduce dusting. Leaving a gallon ‘free’ in the container allows mixing/stirring.
• Gently stir the mixture up with a paddle or stirrer
• Soak in the water for 24 hours
• Mix the paint until it is uniform-appearing. A drill-mixer is best for this, since the “shear” gives a better paint. However, mere stirring or shaking will create a usable paint. The coating is ready-to-use at this point as a ceramic/refractory paintable coating. For a ‘touch-up’ coating, a thinner paint can be made by adding 1 gallon of water to 2 gallons of the liquid paint made above and stirring until uniform. This coating can be used for glass melting areas, whether involving ceramic or stainless substrates that need the coating … as a more-useful replacement for Alumina/Kaolin ‘washes’, for instance.
NovaMix powder made as a liquid-paint provides a ceramic layer which is generally unreactive to many molten materials. The coating bonds readily to ceramic or metal substrates to provide a well-bonded general-utility ceramic coating that is also rather nonwetting with nonferrous metals. The liquid coating made from NovaMix can be used for sealing ceramic/refractory surfaces to prevent melt-contamination while extending the ceramic/refractory lifetimes.
More Detailed Use Notes/Instructions
(1) Making the “Just Add Water” paint:
After adding NovaMix powder and water to a container, the stirring-up step can involve stirring with a paddles and/or shaking [if smaller amounts are made at a time] the mixture until lumps disappear. Letting the mixture sit for 24 hours [or, at a minimum, overnight] allows the ingredients to “mingle” well and is necessary for making a good coating.
The best way to mix the coating is with a drill-mixer or a propeller-mixer (preferably creating some “shear”) – insuring that the constituents are fully blended into the water to create the ready-to-use ceramic/refractory liquid paint. Typically, only minimal mixing, stirring, or shaking is required. And, as stated above, if a mixer is not available, a usable paint can be made by simply stirring with a paddle or shaking the container or putting the container onto a jar-mill-roller for awhile.
(2) Preparing the surface(s) to be painted, then painting and drying.
• Clean surfaces to be coated of any oils, dirt, scale etc. Application may be by brushing, air-spraying, or dipping [although care must be taken to insure that the coating is totally dry and free from moisture if dipping is utilized {note: a dipped coating dries from the outside and may ‘appear’ dry while still containing moisture}]. Applying to a warm surface [i.e., around 40-50 C if by brushing or dipping; or around 250-300 C if by air-spraying] is helpful.
• Allow to dry thoroughly before use. It is OK to apply more layers after drying each one. Never contact wet water-based coatings with molten materials. The thoroughly dried coating is always OK to use to high-temperatures.
• Thinner coatings [0.05 to 0.15 mm] often perform better than thicker ones.
