Unlocking the Full Potential of Ethylene Bis-Stearamide in Adhesives

In the world of adhesives, Ethylene Bis-Stearamide (EBS) is a vital ingredient that is often overlooked by the users. Its unique properties and characteristics make it an excellent choice for a variety of adhesive applications. From increasing the adhesive strength to improving the processability and reducing the cost – EBS can do it all. In this article, we explore the many benefits of EBS and how it can unlock the full potential of adhesives.

What is Ethylene Bis-Stearamide?

Ethylene Bis-Stearamide is a synthetic wax-based material that is widely used in the adhesive industry. It is produced by the reaction of ethylene diamine with stearic acid. The result is a waxy solid that has a high melting point and is insoluble in water. Due to its molecular structure, EBS is highly resistant to chemicals, ultraviolet light, water, and heat. It is also non-toxic, making it an ideal choice for applications where food contact is possible.

Improving Adhesive Strength

One of the significant benefits of EBS in adhesives is its ability to increase the adhesive strength. When used in hot-melt adhesives, EBS acts as a tackifying agent. That means it increases the stickiness of the adhesive, resulting in better bonding. EBS has been shown to improve the shear strength and peel strength of adhesives, making it an ideal choice for applications where a strong bond is crucial. EBS has been tested in a range of applications, from packaging materials to automotive adhesives, and its effectiveness has been proven time and time again.

Improving Processability

Another benefit of EBS in adhesives is its ability to improve the processability of the product. In hot-melt adhesives, one of the most significant challenges is ensuring that the adhesive flows smoothly and evenly. However, when EBS is added to the adhesive formulation, it reduces the viscosity of the adhesive. As a result, the adhesive is easier to process, which can save time and money in the manufacturing process. This is particularly important in high-volume applications, where even a small improvement in processing can translate into significant cost savings.

Reducing Cost

EBS can also help to reduce the cost of adhesives without compromising their quality. Due to its unique properties, EBS is an excellent substitute for more expensive materials in adhesive formulations. For example, in hot-melt adhesives, EBS can be used to replace a portion of the more expensive tackifying resins. This can result in a significant reduction in the cost of the adhesive without sacrificing its performance. Additionally, due to its low toxicity, EBS can be used in applications where other toxic substances cannot, saving the manufacturer the extra cost of substituting these substances.

Improving Heat Resistance

Heat resistance is another crucial property of adhesives, particularly in high-temperature applications. EBS has excellent heat resistance, making it an ideal choice for high-temperature adhesives. When used in hot-melt adhesives, EBS can withstand temperatures of up to 150°C without melting or losing its effectiveness. This makes EBS an ideal choice for applications such as automotive adhesives, electronic adhesives, and packaging materials.


In conclusion, Ethylene Bis-Stearamide is a versatile ingredient that has many benefits in adhesives. Its unique properties make it an ideal choice for applications where adhesive strength, processability, heat resistance, and cost are critical. Whether it is in hot-melt adhesives, pressure-sensitive adhesives, or other adhesive formulations, EBS can unlock the full potential of adhesive products. By utilizing the full potential of EBS, adhesive manufacturers can create more effective, efficient, and affordable adhesive solutions for their customers.
