What is Petroleum Resin GA-115B?
Petroleum Resin GA-115B, also known as Hydrocarbon Resin GA-115B or Petrez, is a C9 aromatic hydrocarbon resin derived from the by-products of petroleum cracking. Petroleum Resin GA-115B, sometimes referred to as Petrez resin, is widely used as a tackifier in adhesives and coatings. Produced through pre-treatment, polymerization, and distillation, it is a thermoplastic resin with low molecular weight ranging between 300–3000. This resin is not used independently but acts as a performance-enhancing additive, commonly blended with other resins to serve as a tackifier, viscosity adjuster, and modifier.
Known for its excellent solubility, water and chemical resistance, and strong adhesion properties, it is widely utilized across coatings, rubber, adhesive, ink, and road marking industries. Chemex Chemicals ensures a consistent supply of C9 and C5 hydrocarbon resins, making it a reliable partner for industries across India.
