Ester cured Phenolic No-Bake resin
Resin
This is the most users- friendly No bake chemical binder system. All types of materials viz. Steel, Iron, Aluminium and Bronze can be cast using COOLSET 3010 / COOLSET 3020 system. Being Nitrogen free and having good thermal characteristic, it produce Nitrogen and hot tear defect free castings. Hence, COOLSET 3010 / COOLSET 3020 System is recommended for making critical and high value steel castings. Binder being fully water miscible, this system is easy to clean with water.
Advantage offered by the system:
- Free from Nitrogen, Sulphur & Phosphorous.
- Water soluble Resin (Core box, patterns & mixers can be washed & cleaned with water).
- Non corrosive hardners.
- Easy stripping from the pattern. No sticking.
- Can be used with all types’ sands of high acid demand values.
- Collapsibility is very good.
- Evolve minimum gas during pouring.
- Offer superior castings which are free from veins, scab and hot tears.

Recommended Recipe (Standard Procedure):
- Resin: 1.8 to 2.2% by Wt. of Sand
- Hardner: 20-22% by Wt. of Resin
Hardner Practice:
- COOLSET A/210 is a Fast Hardner grade offering a Bench Life of 3 to 9 Mins.
- COOLSET A/211 is a Slow Hardner grade offering a Bench Life > 10 Mins.
- Customized Hardner grades can be offered to suit the varying bench life needs of foundries.
- Recommended Hardner addition level is 20 to 25% of Resin. Addition level out of the recommended range does not influence either setting time or core settings.
