| Coumarone-indene resin |
 |
CUMAR P-25 Resin is a semi-solid, amber colored coumarone-indene resin. Due to its low unsaturation and other properties, formulators will find that it is resistant against oxidation, moisture, alkali and dilute acids.
Furthermore, its low softening point allows this resin to be useful as a non-drying plasticizing resin.
It is primarily used in the manufacture of rubber compounds and waterproofing.
