Advantages and Applications of High Softening Point Petroleum Resins in Offset Printing Ink | Ecopower

HC-9130 and HC-9140

C9 Petroleum Resin is a key component in offset printing ink, significantly enhancing ink performance and print quality. The C9 petroleum resin grades HC-9130 and HC-9140 offered by Ecopower Company, belonging to the high softening point petroleum resin series with softening points of 120-130°C and 130-140°C respectively, provide unique performance advantages for offset printing ink. Below are the overall advantages and application characteristics of high softening point petroleum resins in offset printing ink:

Overall Advantages of High Softening Point Petroleum Resins：

Excellent Heat Resistance

The high softening point characteristics of HC-9130 and HC-9140 ensure stability in high-temperature environments, preventing ink from softening or deforming during the printing process. This makes them particularly suitable for high-speed printing and high-temperature drying processes.

Enhanced Ink Durability

High softening point petroleum resins improve the wear and scratch resistance of ink, making printed products more durable and extending their lifespan.

Improved Ink Gloss

HC-9130 and HC-9140 petroleum resins significantly enhance the glossiness of ink, resulting in a smoother and more vibrant print surface, ideal for high-quality printing requirements.

Increased Ink Adhesion

High softening point petroleum resins enhance the adhesion of ink to various substrates (such as paper, cardboard, and plastic), ensuring that printed patterns are durable and resistant to peeling.

Optimized Ink Viscosity

HC-9130 and HC-9140 petroleum resins effectively adjust ink viscosity, making it more suitable for offset printing processes and ensuring consistent ink transfer and print quality.

Enhanced Weather Resistance

High softening point petroleum resins improve the water, light, and heat resistance of ink, ensuring print stability in outdoor or challenging environments, preventing fading or deterioration.

Application Characteristics

HC-9130 (Softening Point: 120-130°C)

Suitable for printing inks requiring high gloss and adhesion, commonly used in high-quality printed products such as books, magazines, and packaging. Its moderate softening point ensures stability in high-temperature environments, making it ideal for high-speed printing and high-temperature drying processes.

HC-9140 (Softening Point: 130-140°C)

Offers higher heat resistance and wear resistance, making it suitable for printed products requiring exceptional durability, such as outdoor advertisements, packaging materials, and labels. Its high softening point ensures excellent performance even in extreme environments.

Recommended Usage

To achieve optimal results, the recommended usage of Ecopower HC-9130 and HC-9140 petroleum resins is as follows:

HC-9130: Recommended addition is 8%-12% of the total ink weight, with specific amounts adjustable based on printing requirements and material properties.

HC-9140: Recommended addition is 10%-15% of the total ink weight, suitable for printed products requiring high weather resistance and wear resistance.

Conclusion

High softening point petroleum resins (HC-9130 and HC-9140) excel in offset printing ink, significantly improving heat resistance, durability, gloss, adhesion, and weather resistance. Ecopower Company's HC-9130 and HC-9140 petroleum resins, with their high softening point characteristics, are the ideal choice for high-quality printing inks, widely used in books, packaging, outdoor advertising, and more.
