W-10 MOLD COAT COMPOUND
W-10 is prepared for severe casting conditions and is packaged wet in gallon containers, ready for use.
Industrial grid casting, particularly with calcium alloy, is usually very detrimental to normal mold coat compounds. W-10, because of its tough heat-resistant compounds, gives added casting time. It is a very tough binding mold spray, and can be used "as received" for most industrial and calcium grid casting. It contains a preservative for long shelf life.
W-10 has also been found very effective as an additive to normal mold coat spray for most SLI grid casting. W-10 should be mixed with other mold coats at a ratio of 1 to 1. When mixing with other mold coats, the material should be mixed at the same consistency normally sprayed on the mold. A mixture of half W-10 and half Wirtz
X-400, X-500, or any other cork spray, will usually give longer cork life. The exact ratio of mixing can be varied to suit individual casting requirements.
Example - for more insulation add more regular mold coat, for less insulation and a tighter binding spray, add more W-10. Most casting requirements can be met with a mixing ratio of 1 to 1.
Adding W-10 mold spray does not increase the cost of present cork mix. By mixing 1 gallon of each, a total of 2 gallons is obtained. This 2-gallon mixture will then be more effective and last longer than 2 gallons of normal mold coat.
WIRTZ MOLD COAT
X-400 cork is packaged in dry form and, when mixed, makes one U.S. gallon of mold spray. X-400 cork contains ground cork and Bentonite Clay with high insulating properties for general purpose grid casting. Must be ordered in multiples of 25 packages.
X-500 cork is packaged in dry form and, when mixed, makes 1-1/2 to 2 U.S. gallons of mold spray. X-500 cork contains ground cork and Bentonite Clay with moderate insulating and binding properties for high speed grid casting. Must be ordered in multiples of 25 packages.
W-10 is packaged wet in 1 gallon containers. It has moderate insulating and high adhesion properties.
W-10 can be mixed in varying proportions with X-400 or X-500 to give improved "corking" durability.
Best results can be obtained by mixing no more than a 2-day supply of mold coat at-a-time.
