- Understand the role of pine resin for paper sizing, improving paper strength and resistance to water and ink absorption for better printability.
- Learn how rosin in printing inks acts as a binder, improving adhesion, color intensity, and drying properties, essential for vibrant and durable prints.
- Discover the significance of rosin for the rubber industry, where it functions as a softener and tackifier, enhancing elasticity and durability in products like tires and footwear.
Key Advantages
Versatile Industrial Uses
Gum rosin serves as an essential binder for paints and coatings, improving gloss, adhesion, and durability. Its use as a component in adhesives, particularly hot melt and pressure-sensitive types, highlights its excellent tackifying capabilities.
Eco-Friendly and Renewable
As a natural resin derived from pine trees, gum rosin offers a sustainable and eco-friendly alternative to synthetic resins, aligning with growing industry demands for greener materials.
Enhanced Product Performance
The unique chemical structure of rosin, including abietic acid, enables it to enhance product performance in various applications. For example, its use as a paper sizing agent improves paper quality, while its role in printing inks ensures better adhesion and color.
Key Applications
Adhesives & Sealants
Rosin was widely used as an ingredient of some kind of adhesive; especially in heat melt adhesive, pressure sensitive adhesive and rubber adhesive. Rosin mainly is used to enhance the strength, plasticity and viscosity of adhesive.
Paints & Coatings
Rosin is a basic material for the paint industry because rosin is easy to dissolve in alcohol, gasoline, turpentine, and other organic solvents. Rosin always is converted to resinate, and then refined with drying oil such as tung oil and mixed with volatile solvent to produce various lacquers.
Printing Inks
Rosin mainly acts as a color carrier and enhances color adhesive ability in printing ink. Rosin takes about 7% of the quality of printing oil in China.
Paper Manufacturing
Most rosin was applied to the papermaking industry as a sizing agent. Rosin paper sizing agent can prevent printing oil soaking and dispersing from paper, improves the strength and smoothness of paper; enhances the anti-abrasion of paper.
