C9 Aromatic Resin (for paints, inks, rubber and HMA)
Low-molecular-weight thermoplastic aromatic petroleum resin produced from C9 distillate, a by-product of ethylene plants; a light-yellow transparent solid.
Key properties
- Softening point 95–150 °C (grade dependent)
- Colour (Gardner) 4–18
- Acid value max. 0.5–1
- Good solubility, water resistance and insulation
- Chemical stability in acid and alkali conditions
