ZIROX 25 Ceramic Coating


An off-white, very fine-grained and high-grade, neutral, water- based Zircon coating.


ZIROX 25 is suitable for a wide range of applications in the ferrous and non-ferrous melting industries.

ZIROX 25 has been specifically formulated to produce a very durable refractory barrier which protects refractory materials and metal tools against molten metal attack. This is particularly important where there is a risk of contamination, e.g. iron contamination of aluminium and copper based alloys.

ZIROX 25 also highly effective as a release agent enabling easy removal of solidified metal and dross from ingot moulds, carrying ladles, tundishes, launders and buggies.


ZIROX 25 is supplied at a viscosity of 120 degrees Baume'
The coating is normally diluted 1: 1 with water, but can be applied undiluted where metal surfaces are being treated for the first time.


ZIROX 25 can be applied by brushing, dipping, spraying or swabbing. A long lasting ceramic coating is formed when the thoroughly air dried coating comes into contact with molten metal. Alternatively the ceramic coating can be pre-formed by torch-drying.


10 - litre metal pails


  1. ZIROX 25 is non-toxic.
  2. In the event of eye contact, irrigate thoroughly with clean water for 10- 15 minutes.


Prior to initial application of coating, the metal surface should be :
