Introduction : Core Paste ,Hot Shell Adhesives

In the No Bake or Air Set Process, molds/cores are produced using a resin bonded air setting sand. These molds/cores are allowed to harden under normal atmospheric conditions. Quite often these molds/cores are broken or are actually sectional cores and as such require Core Paste to join the pieces together. Water based, silica free products are available for this need. If a faster drying time is required, solvent based products are also available.

Description: Core Paste , Hot Shell Adhesives

In the Shell or Hot Box Process, resin bonded sand or a sand/resin mix is placed on a heated metal pattern for a short period of time to form a partially hardened shell. The bulk of the sand mixture inside the shell is removed for further use and then the pattern and shell are then heated to further polymerize the sand/resin mix. The shell is then removed from the pattern. As with the No Bake Process, these shells are broken or are sectional cores and require an adhesive in order to piece them together. Hot Shell Adhesives containing a thermosetting resin are typically used for this. These Hot Shell Adhesives are generally applied to the hot shell cores and molds and typically utilize a liquid carrier that does not boil or dry out rapidly, allowing the operators sufficient time to position the pieces.

  • Foundry Adhesive 300

    FoundryGeneral® Foundry Adhesive 300 is a ready to use hot shell core and mold paste. FoundryGeneral® Foundry Adhesive 300 is a slower version than the 100 through 250 series with a longer open time for very hot shells or in applications where prolonged open times before shells are closed is required. FoundryGeneral® Foundry Adhesive 300 also tends to hold a better bead than the 100 through 250 series.

  • Foundry Adhesive 250

    FoundryGeneral® Foundry Adhesive 250 is a ready to use hot shell core and mold paste. When applied to the hot drag of a shell mold, FoundryGeneral® Foundry Adhesive 250 does not boil or dry out quickly, allowing the operator sufficient time to properly position the hot cope half of the mold. After 45 seconds of curing under pressure in the mold press, FoundryGeneral® Foundry Adhesive 250 develops an extra strong bond which eliminates metal run outs at the parting line and provides casting dimensional accuracy across the parting line.

  • Core Paste 9672

    Core Paste 9672 is a fast drying, solvent based adhesive used to join or repair molds and cores in the foundry industry. This adhesive has excellent suspension properties, therefore settling will not occur with extended storage. It has an excellent tensile strength and zero VOC content. In addition, the fast drying characteristics of this product make it ideal for production because it is able to meet the demands of high production rates and efficiency.

  • No Bake Core Paste 1000

    FoundryGeneral® No Bake Core Paste 1000 is a ready to use air drying paste that is silica free. It is ideal for automatic dispensing paste that is silica free. It is ideal for automatic dispensing systems since it does not contain material that will abrade or wear out the equipment. FoundryGeneral® No Bake Core Paste 1000 penetrates into the sand matrix to form a strong bond and is primarily used with no bake systems, but can also be used with core oil, hot box and cold box systems. Once completely dry, an inorganic bond is formed which produces very little if any gas evolution on pouring. The set time can be reduced by heating the joining surface to about 250 °F.
