Environmentally Friendly Sodium Silicate Binders

Posted by Hill and Griffith Company on Nov 7, 2017 9:33:12 PM

Corosil (Silicate Products) - Application to Aluminum Castings Sodium Silicate based products are one of the most environmentally friendly products that can be used in a core room.

The Indianapolis Manufacturing Facility has an excellent product line of Sodium Silicate Binders (Corosil and COBond). There have always been problems associated with the application of sodium silicate binders. The principal problem is in their inability to "shakeout" of a casting. The term "shakeout" applies to the ability or inability to remove the bonded sand from the solidified casting. As everyone would appreciate, if a foundry cannot remove the sand from the casting easily their costs of producing the casting would increase. In comparison, the less environmentally friendly processes do not have the severe difficulty of "shakeout".

Selecting A Core Adhesive For A Shell Core

Posted by Hill and Griffith Company on Nov 1, 2017 1:26:40 PM

It is extremely important to select the correct adhesive to receive the maximum efficiency out of the selected product.

There are a number of adhesive applications that must be considered. A shell core may employ an adhesive immediately after the core is removed from the box (the core will be extremely hot and this is not the preferred time to apply an adhesive), the core may be "warm to the touch" and when the core is sufficiently cool. It is important to realize that there is not a single adhesive for all of these applications.

When a shell core is extremely hot it is very difficult to apply an adhesive that will create a sufficient bond to maintain the strength at the joint of the core. The only adhesive that will meet this application is a water based core adhesive that is designed for "thermal curing" (oven curing). The product that we recommend for this application is Red Chief. However, it very important to realize that this is not the best application time for any core adhesive.
