The furan no-bake process consists of a two part air-setting system involving a Resin (pt1) and Acid hardner (pt2). This systemis developed to suit a wide variety of applications across the ferrous and non-ferrous foundries. The Furan NB system can be mixed in both batch as well as continuous mixers. In a batch mixer however it is recommended to mix the acid co-reactant first with sand followed by resin.

Polyurethane No-Bake Binder System
The polyurethane no-bake (PUNB) binder is a three-component system comprising of a liquid phenol-formaldehyde resin (part1), liquid polyisocyanate (part2) and a liquid catalyst (part3). The catalyst (part3) controls the curing rate of the reaction if required and in turn controls the stripping time of the core / mould. The PUNB system can be mixed in batch as well as continuous mixers but the latter is preferred due to the rapid speed of the reaction. Addition of the part 3 (catalyst) can be adjusted to get the desired stripping time. Varying the ratio of part1 and part2 does not change the speed of the reaction.

Binder System Shell moulding
The shell mouldingbinder is a 2-component system comprising of a liquid novolac type PF resin and a powder based hardner (part2). Also referred to as the Croning process it has been applied to foundries across the globe for over 60 years. The shell resin binder system must be mixed in a batch mixer using the warm coating process. Addition levels and Coating cycles may vary from one customer to another depending on requirements.
