Main applications

1.Rubber industry
It is widely used for various rubber product, such as tyre, conveyor belt, triangle belt, rubber tube, NBR and etc. Adding this to the rubber has many functions like softening, reinforcing, viscosity improving and dispersion. On one word, it will improve the processing capacity of rubber.
2.Waterproofing material
For waterproof material, its functions are viscosity improving, acid and alkali resistance and antiaging.
3. Paint
It is usually used in coumarone resin with softening point 100#--110#. Coumarone resin can improve the gloss of paint. It can also improve the film adhesion, hardness, anti-acid and anti-alkali property.
4. Modified asphalt
Improve the property of modified asphalt.
5. Fireproofing material.
It can be used for binding agent. There are more polar functional groups which has good adhesiveness with fireproofing material. It also has very high bonding strength under high temperature.
