1、Terpene derivative
Herein, we propose a terpene-modified polysiloxane-based polyurethane that solves the above-stated problems. In the presence of the Karstedt catalyst, isobornyl acrylate (IBOA) was introduced into the branch of hydrogen-containing silicone oil (HSO) through the hydrosilylation reaction.
2、Differences in Terpene Resins
Compared to synthetic polymers like polyvinyl alcohol (PVA) and polyacrylic acid (PAA), terpene resins exhibit significant differences. Firstly, their origin lies in natural plant sources, whereas PVA and PAA are artificially synthesized.

Preparation and properties of waterborne UV
Herein, the epoxy soybean oil-based acrylate (AESO) was modified with cyclic anhydride, neutralized by triethylamine, then dispersed in deionized water to form the high bio-based content waterborne UV-curable resin (WAESO) with good storage stability.
Progress of bio
In this review, relevant studies regarding waterborne bio-based coatings in recent years were presented and organized according to the types of binders incorporated in the coating formulations, i.e. polyurethane, polyester, alkyd, and epoxy.
Terpene derivative
With increasing desires to protect the environment, volatile organic solvent emissions have been restricted, and there is a trend in developing waterborne polyurethanes. However, poor water resistance and low mechanical strength of waterborne polyurethane are major obstacles.
Terpene Phenolic Resin Emulsion
Foreverest™ Terpene Phenolic Resin Emulsion TPR602E is an aqueous, solvent free resin based on terpene phenolic resin, mixture with waterborne dispersion of a terpene-phenol resin.
The difference between waterborne and oil
Oil-based polyurethane is not environmentally friendly compared with water-based polyurethane in the production, use and waste treatment process. There is a strong pungent smell and organic gas volatilization.
In today's chemical industry, terpene resins have become a focus of attention due to their broad application range and superior performance. Among them, waterborne terpene resins and oil-based terpene resins, as two distinct forms, exhibit significant differences in preparation processes, physical properties, and application scopes. These differences not only affect their performance but also pose higher demands for environmental friendliness.
1. Preparation Process The primary distinction between waterborne and oil-based terpene resins lies in their solvents. Waterborne terpene resins typically use water as a solvent or diluent, while oil-based terpene resins rely on mineral oil, vegetable oil, or other organic solvents. This difference leads to variations in energy consumption and environmental impact during production. Waterborne terpene resins are more eco-friendly, energy-efficient, and consume less water. In contrast, the production of oil-based terpene resins often involves substantial petroleum resources and generates more harmful emissions, posing greater environmental pressure.
2. Physical Properties Waterborne terpene resins generally exhibit better solubility and fluidity, making them widely used in coatings, adhesives, and other fields. Additionally, their higher stability ensures that products formulated with waterborne resins are less prone to layering or precipitation during storage and application. In comparison, oil-based terpene resins offer superior mechanical strength and weather resistance. they may require additional auxiliary materials to adjust viscosity during application, increasing operational complexity.
3. Application Fields The choice between waterborne and oil-based terpene resins depends on multiple factors. In coatings and adhesives, waterborne resins are increasingly favored due to their environmental advantages and ease of application. Meanwhile, oil-based resins remain dominant in industries like construction and automotive manufacturing, thanks to their excellent durability and strength. with growing environmental awareness and technological advancements, the application scope of waterborne terpene resins is expanding, showing potential in sectors such as electronics and textiles.
4. Future Development Trends Both waterborne and oil-based terpene resins face pressure to transform and upgrade. To meet market demands and enhance competitiveness, manufacturers of waterborne resins must invest in research to improve environmental performance and cost-effectiveness. Similarly, oil-based resin producers need to explore greener production processes to reduce environmental harm. Cross-industry collaboration will play a critical role in sharing resources and technologies to drive the sustainable development of terpene resins.
Waterborne and oil-based terpene resins represent two distinct product categories with significant differences in preparation, properties, and applications. These differences reflect both the characteristics of the resins and the chemical industry's pursuit of environmental sustainability. Balancing environmental protection with performance optimization will remain a shared challenge and opportunity for both types of terpene resins in the future.
