This product is primarily used as an additive in industries such as paints, rubber, adhesives, inks, plastic floor tiles, and modified asphalt.
Ink industry
　　◎ Inks primarily use C9 petroleum resins with high softening points. The addition of petroleum resin to inks enhances color development, accelerates drying, and boosts gloss, while also improving printability. Furthermore, it can enhance the rheological properties of printing inks and improve the stability of the vehicle, making it suitable for a wide range of printing inks.
Paint industry
　　◎ Paints primarily use C9 petroleum resins with high softening points; when incorporated into paints, these resins enhance gloss, improve film adhesion, increase hardness, and boost resistance to acids and alkalis. They are employed in the production of road‑marking paints and anti‑rust coatings, and are also widely used in marine paints and alkyd paints.
Adhesive Industry
　　◎ Petroleum resins with softening points in the range of 100–130°C primarily replace traditional modified rosin and terpene resins. They exhibit excellent adhesion; incorporating petroleum resin into adhesives and pressure-sensitive tapes enhances adhesive strength, acid resistance, alkali resistance, and water resistance, while also effectively reducing production costs.
Tires and Rubber Products
　　◎ Tires and rubber products primarily utilize low‑softening‑point C9 petroleum resins. These resins exhibit excellent miscibility with natural rubber particles and have minimal impact on the rubber vulcanization process. Incorporating petroleum resin into tires and rubber formulations serves to enhance adhesion, improve reinforcement, and provide softening effects.
