COOLSET 1001 is a completely nitrogen free Phenolic resin, activated with acid catalyst and used in production of steel, alloy steels and sophisticated iron castings, specially those which are prone to subsurface NITROGEN PINHOLING. The product is highly recommended for use in thick section castings as it offers high hot strength, excellent scratch hardness at high temperature, resistance to metal penetration and mould dilation.

The resin when tested shall have the following properties
| Appearance | Dark brown, viscous liquid |
| Density at 25°C | 1.20 — 1.22 gm/cc |
| Viscosity at 25°C | 6-8 Secs (in B6 ford cup) |
| PH | 6.2 – 6.5 |
| Nitrogen | Nil |
| Free Formaldehyde | Less than 0.1 % |
| Free Phenol | 6 % maximum |
| Gas Content | Less than 40 ppm |
Catalyst:
The catalyst should be super saturated solution of Para Toluene Sulphonic Acid (PTSA).
| Appearance | Brownish transparent liquid |
| Purity | 70% |
| Sp. Gravity at 25°C | 1.2 |
| Gel. Time | 35 seconds |
COOLSET 1001 is recommended for its:
- Nil Nitrogen content.
- Excellent strength and scratch hardness with comparatively lower resin addition.
- Comparatively lower gas content.
- Well controlled setting time.
- Efficient reclamation of resin sand.
