ZIROX 25 Ceramic Coating

DESCRIPTION

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

FUNCTION

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.

DILUTION

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.

RECOMMENDED APPLICATION

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.

PACKAGING

10 - litre metal pails

HEALTH AND SAFETY

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

PREPARATION OF METAL SURFACES FOR COATING

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

• Free from any form of oil or grease.
• Free from any previous coating.
• No rust or scale should be present.
• Therefore surfaces to be coated should be de-greased, using a suitable solvent and preferably shot
  or sand-blasted to give a rough oxide-free surface. This will ensure that the refractory coating will
  adhere tenaciously to the surface and provide a long life.
