Resin Systems


From molding to shakeout, REFCOTEC has your resin needs covered!



REFCOTEC carries a full line of foundry resin systems for all different alloys casted in the foundry industry. There are many different resin systems used in the production of making sand molds and cores and consideration of the resin system should be based on the alloys being casted and the equipment available. Resin systems are available in 2 and 3 part systems where a type of catalyst or co-reactant is used to cure the sand; this could be in a liquid or a gas form.

There are also resin systems available that are cured with heat.  REFCOTEC’s technical staff can help determine the right product for the alloy and equipment.  We can also work directly with the foundry to find a solution by custom formulating a resin system that solves a specific issue in the foundry.

Alkyd based resin blends exhibiting good plasticity and minimal sensitivity to foundry variables. ALKAST systems require a polyisocyanate coreactant. They are produced with reaction speeds from ten minutes to two hours. If needed, a third component can be added at the mixer to obtain faster strip times.


Acid catalysts used with furan and phenolic no-bake resin systems. Proper catalyst selection is an important factor in binder performance. CHEMKURE catalysts may be toluene sulfonic acid (TSA), benzene sulfonic acid (BSA) or blends of both (TSA/BSA). They are available in water, alcohol and water/alcohol solutions.


Oils used in combination with water and cereal to develop an initial green strength for handling strength and a strong chemical bond when baked. COROIL cores exhibit a combination of very high strength and very good shake out. They are often used to make intricate shapes. Solventless formulas reduce concerns with odors and emissions.


Furan resins offering excellent dimensional accuracy, high strength and effective reclamation by thermal or mechanical equipment. DURAKAST resin systems utilize acid catalysts selected for specific foundry requirements. Furan binders are the most popular choice of foundries around the world.


Phenolic ester, no-bake resin most often selected for it’s low odor, high hot strength and excellent pattern release. A wide range of ester coreactants are available to meet the work time and strip time needs of any foundry.


Phenolic urethane cold box resin systems designed for use in high production core and mold manufacturing operations where an amine gas is used for catalyzation. There are several different resin systems to accommodate the unique requirements of the foundry.


Phenolic resins cured by acid catalysts. PHENKAST products are favored for their excellent pattern release, hot strength, resistance to metal penetration and economy. A wide range of acid catalysts allows each foundry to select the work time and strip time to fit their needs.


Resin systems designed specifically for non-ferrous casting applications. They demonstrate excellent shake out for metals that solidify at low temperatures. This system offers maximum performance with minimum odor.


Sodium silicate binders, catalysts and co-binders, which are virtually odor free and smoke free. These binder systems can be cured by the use of carbon dioxide gas or with REFCOBOND liquid catalysts. REFCOBOND is the industry’s most environmentally safe binder.


Three part phenolic urethane no-bake systems designed for use where the foundry is looking for adjustable strip times, from fast to slow, with a liquid catalyst. They are available in various grades to meet the needs of the foundry.
