STEELCOTE ZR 185
A convenient, easy to use dressing of wide application for
moulds and cores of all types, but especially silicate and resin
STEELCOTE ZR 185 is a white, spirit (Iso-propanol) based zircon
coating, in almost ready for use slurry form, with excellent
brushing and swabbing characteristics. Designed specifically for
steel castings of any section thickness, but is equally effective
in severe situations involving the whole range of cast irons,
copper and nickel base compositions and even the light alloys.
INSTRUCTIONS FOR USE
For most purposes STEELCOTE ZR 185 is almost ready to use form
as supplied but some slight dilution may be necessary using
Iso-propanol solvent. It may be applied by brush, swab or spray, or
cores may be dipped.
STEELCOTE ZR 185 may be used on any substrate that will accept a
spirit-based dressing, for any of the conventional cast metals and
for both moulds and cores. While it exhibits excellent suspension
and anti-settlement properties it should, after transport or
long-period standing, be thoroughly mixed before use.
After application the dressing should be ignited. To avoid
solvent loss by evaporation, large moulds or cores should be
dressed in small areas ignited individually.
Allow the coating to burn out and to cool to ambient temperature
before closing and casting, or alternatively close and cast while
still hot, avoiding the intermediate situation.
•High solids/ low gas content dressing, utilising ultra modern
suspension and bonding techniques.
•Wide flexibility in terms of metal type, casting section and
sand bond used.
•Low gas evolution on casting, which reduces problems of gas
entrapment, blowing, explosion penetration and oxide folding.
•Excellent brushability, even on multiple application on warm
moulds, allowing easy and trouble free use.
