Core and Mold Washes

Shurcoat ZA-95

• SFP SHURCOAT ZA-95 is a high refractory zircon based alcohol coating, it lends itself both to cores and molds and assures good consistent blending.
• SHURCOAT ZA-95 is recommended when a protective barrier is required to prevent or minimize metal penetration into the sand. It promotes excellent casting surface finish in high temperature conditions.
• SHURCOAT ZA-95 can be utilized with steel, gray iron, malleable iron, ductile iron, copper base alloys and in aluminum casting where a chill effect is desired.
• SHURCOAT ZA-95 can be air dried. To speed drying the coating can be ignited or oven dried.

Recommended Baumé

For spraying                  55º- 65º
For brushing                  80º – 85º
For swabbing                80º – 85º
For dipping                    55º – 60º

Use three parts of SHURCOAT ZA-95 and one part of IPA (isopropyl alcohol) to reduce the coating to approximately 60º Baumé.

Application
SHURCOAT ZA-95 can be applied to green sand molds, all known chemically bonded sands, hot resin systems and sodium silicate systems.

Note: On chemically bonded systems a “when to wash” should be observed. The general rule is to apply the coating after the surface has been completely cured. Since the actual waiting time before applying a coating varies, depending upon the conditions. Example, if the strip time is five minutes then it is suggested to wait another five minutes before the coating is applied.

Recommendation
Agitation prior to use may be necessary.

Packaging
45 gallon steel drums (approx. 850 # net) or 5 gallon pails (approx. 65 # net)

 

Shurcoat GA-100

Shurcoat GA-100 is a premium graphite coating formulated for use on cores, molds, or chills. As a graphitic coating it will exhibit excellent resistance to burn-in, excellent peel for iron and non-ferrous castings and good separation of chills from the casting surface.

Application
• Shurcoat GA-100 can be used alone or as a topcoat over zircon or other refractory coating bases to provide for extra burn-in resistance. This product can be sprayed, brushed, or swabbed.
• If Shurcoat GA-100 is applied to chills they should be clean and dry before applying this coating.
• Shurcoat GA-100 can also be used under other coatings in hot spots or trouble areas as a supplement. The following chemical and physical properties are provided as reference only. The chemical data is an approximate analysis based on formula weights, test results, and supplier data.

General Use Information
• Shurcoat GA-100 is supplied as a premix that can be diluted with anhydrous Isopropanol (isopropyl alcohol or SFP THINNERS) to the desired viscosity or Baumé. In some application Methanol or Ethanol may also be used as a diluent. However, the dilution ratio and coating properties in use will be a bit different. As used, Baumé is directly related to your production requirements. The optimum Baumé or viscosity can be determined through trial with consideration given to casting properties, surface conditions, drying considerations, and other variables
• Shurcoat GA-100 can be air dried or lit-off depending upon the application and on your time and space constraints. As with any other coating line it is recommended to follow the supplier information for determining Baumé.

Shurcoat GA-300

Product Description
• Shurcoat GA-300 is an alcohol slurry blend of zircon flour and flake graphite. Shurcoat GA-300 lends itself very practically in foundry applications by reducing time and assuring good blending characteristics.
• Shurcoat GA-300 means better castings, provides cores and molds with a highly refractive coating with excellent sand peel from castings, and creates an impermeable barrier between the sand surface and molten metal which results in an improved casting finish.
• Shurcoat GA-300 can be utilized with non-ferrous metals (aluminum, brass and bronze), gray, ductile and malleable iron.
• Shurcoat GA-300 can be air dried. To facilitate drying, the coating can be ignited or even dried

Recommended Baumé

For Spraying               35º – 50º
For Brushing               70º – 85º
For Swabbing             40º – 50º
For Dipping                 28º – 35º

 

General Use Information
• Three (3) parts of Shurcoat GA-300 to One (1) part of alcohol (isopropyl alcohol or SFP THINNERS) by volume will produce approximately 50º Baumé.
• 1½ parts of Shurcoat GA-300 to One (1) part of alcohol (isopropyl alcohol or SFP THINNERS) by volume will produce approximately 28º Baumé.
• Shurcoat GA-300 can be applied to green sand molds, all known chemically bonded and hot resin systems. Also recommended for use with (CO2) sodium silicate systems.
• On chemically bonded systems, a “when to wash” should be observed. The general rule is to apply the coating after the surface has been cured. Since the actual waiting time before spraying a coating varies, depending upon the conditions, it is suggested that if normal operation includes a five-minute strip, then wait another five minutes before coating.

Recommendation
Agitation prior to use may be necessary.

SphereCoat

SphereCoat is an advanced ceramic composite coating made of specifically for the foundry industry. It prevents molten metal from penetrating into the grains of sand in the core and mold materials. SphereCoat ensures that the sand casting surface remains smooth and heat resistant. SphereCoat prevents erosion of cores and molds during filling and prevents the molten metal from reacting with the molds materials. The overall result is a casting surface free of cracks, penetration, gas, burn-in etc.

SphereCoat can be used with many types of metals such as iron, steel, aluminum and copper based alloys. Because SphereCoat has been engineered from a ceramic composite, there is little to no reaction with specialty metals such as manganese steel.

SphereCoat creates a protective barrier layer with an adequate level of thickness to prevent any contact between the molten metal and mold material. The level of thickness needed will vary depending on the thickness at the wall area, ferro-static pressure, and pouring temperature.

Physical Properties

Nolite SGS Premix 

Product Description
SFP Nolite SGS is concentrated slurry consisting of a blend of Aluminum Silicates and Graphite. This product is designed for dipping and flow coating applications. Under certain conditions this product may also be applied by spraying. The relatively low density of the refractory materials along with a unique combination of flow modification materials produce a coating that builds up well on both horizontal and vertical surfaces. The refractory blend is highly insulating and resistant to burn-in and veining on cores and molds. The sintering point of this product makes it suitable for use in light to medium section iron, aluminum, and other non-ferrous casting processes.

Application
SFP Nolite SGS may be diluted with water as required to optimize the application process. This product should be re-mixed thoroughly before use to ensure uniformity in the drum or pail. As with any foundry core and mold coating, the application process and properties will depend on considerations such as pattern size, casting type, section thickness, and application equipment. The optimum method may be determined with Smelko Foundry Products personnel’s assistance through trial.
