This article presents a comparison of the properties of cores made of sand with acid-curing furfuryl resin, made with 3D technology; the cores were prepared in a conventional way...
Yes, it is possible to mix epoxy resin with sand. This mixture can create a textured surface, increase the material's strength, and improve its adhesion properties. However, the sand used should be clean, dry, and free of any impurities that …
Hot sand is mixed up in a core sand mixer together with solid flake-shaped phenolic resin; the resin melts and covers the quartz grains. This process step is referred to as premixing …
Resin coated sands improve well stimulation results by preventing flowback or fracture evacuation, near the well bore. It is tough coating protect it from crushing and helps to resist …
Resin sand is the molding sand (or core sand) prepared with resin as a binder. The use of furan resin as a binder for moulding sand is a major change in the sand casting process. Since the advent of this method, it has attracted the attention of …
Hot sand is mixed up in a core sand mixer together with solid flake-shaped phenolic resin; the resin melts and covers the quartz grains. This process step is referred to as premixing (premixing time is between 40 and 60 seconds).
The shape of the physical part is built by adding solid particles, made of quartz sand with a thin phenolic resin coating, layer-by-layer and heating it using a CO 2 laser beam. The resin coating fuses and bonds form between the grains of sintered sand (green part).
Shell Fast 2 is a proven proprietary manufactured resin coated sand that cures fast and even, can reduce core box temperatures up to 75 degrees, decreases odor and smoke compared to other phenol/ammonia based products, provides …
Shell Fast 2 is a proven proprietary manufactured resin coated sand that cures fast and even, can reduce core box temperatures up to 75 degrees, decreases odor and smoke compared to other phenol/ammonia based products, provides rapid shakeout, and uses up to 25% less sand for the same volume of cores than typical resin coated sands.
The shape of the physical part is built by adding solid particles, made of quartz sand with a thin phenolic resin coating, layer-by-layer and heating it using a CO 2 laser beam. The resin …
Modified quartz sand was coated with a layer of low-density resin to reduce the overall density of the proppant, thereby improving the suspension of the proppant in the fracturing fluid....
HA's Resital Precoated Sand is based on quartz sand, evenly coated with a layer of Corrodur solid resin and the required curing agent. The excellent flow properties and mould filling …

Shell resin-coated sand (RCS) technologies have been widely used for decades by the foundry industry to produce precision sand castings. These technologies are preferred due to various advantages, such as higher strength per unit of sand, high dimensional stability and superior as-cast surface smoothness.

Resin coated sands improve well stimulation results by preventing flowback or fracture evacuation, near the well bore. It is tough coating protect it from crushing and helps to resist embedment in softer formations. Flow back is the main problem of hydraulic fracturing job, so operators choose an effective proppant to pump into the fractures.
