PARCOR 90 is an immersion cleaner that will disintegrate the sand/resin bond of sand casting. The primary function of PARCOR 90 is to rapidly penetrate and remove the built-up cured sand deposits in the vents and ports of core casting boxes that prevent the proper dispersion of the sand/resin into the recasted mold. PARCOR 90 also has a detergent built into it to help remove grease and oil deposits that might interfere with mold adhesion and curing.

* Cost effective and easily maintained.	* Very safe when used as directed.
* Detergency action to remove oils and greases.
