Shurcoat ZA-95<\/h2>\n

\u2022\u00a0SFP SHURCOAT ZA-95 is a high refractory zircon based alcohol coating, it lends itself both to cores and molds and assures good consistent blending.
\n\u2022\u00a0SHURCOAT 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.
\n\u2022\u00a0SHURCOAT 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.
\n\u2022\u00a0SHURCOAT ZA-95 can be air dried. To speed drying the coating can be ignited or oven dried.<\/p>\n

Use three parts of SHURCOAT ZA-95 and one part of IPA (isopropyl alcohol) to reduce the coating to approximately 60\u00ba Baum\u00e9.<\/p>\n

Application<\/strong>
\nSHURCOAT ZA-95 can be applied to green sand molds, all known chemically bonded sands, hot resin systems and sodium silicate systems.<\/p>\n

Note:<\/strong> On chemically bonded systems a \u201cwhen to wash\u201d 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.<\/p>\n

Recommendation<\/strong>
\nAgitation prior to use may be necessary.<\/p>\n

SphereCoat<\/h2>\n

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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

Nolite SGS Premix\u00a0<\/strong><\/h2>\n

Product Description<\/strong>
\nSFP Nolite SGS<\/b> 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.<\/p>\n

Application<\/strong>
\nSFP Nolite SGS <\/b>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\u2019s assistance through trial.<\/p>\n
