Which adhesive is suitable for high-temperature labels?

Sticker labels play a crucial role in various industries, providing information, branding, and identification on products. However, certain applications require labels that can withstand high temperatures without compromising their adhesion. In such cases, it becomes essential to choose the right adhesive that can maintain its performance even under extreme heat conditions. This article will explore the different types of adhesives suitable for high-temperature labels, ensuring that your labels remain intact and legible in challenging environments.

Silicone-based adhesives

Silicone-based adhesives are widely recognized for their exceptional heat resistance properties. They are capable of withstanding temperatures ranging from -60°C to 315°C (-76°F to 600°F), making them ideal for high-temperature label applications. These adhesives possess excellent thermal stability, ensuring that the labels remain firmly attached even in extreme heat conditions.

One of the key advantages of silicone-based adhesives is their ability to maintain their adhesive properties over extended periods. They exhibit minimal degradation, ensuring long-lasting label performance. Additionally, silicone adhesives have excellent resistance to moisture, chemicals, and UV exposure, making them suitable for a wide range of industries, including automotive, aerospace, and electronics.

Acrylic-based adhesives

Acrylic-based adhesives are another popular choice for high-temperature label applications. They offer good heat resistance, typically withstanding temperatures up to 150°C (302°F). While not as heat-resistant as silicone-based adhesives, acrylic adhesives still provide reliable performance in many industrial environments.

Acrylic adhesives have excellent adhesion to a variety of surfaces, including metals, plastics, and glass. They also exhibit good resistance to chemicals, moisture, and UV exposure. These properties make acrylic-based adhesives suitable for applications where labels need to withstand moderately high temperatures.

Phenolic-based adhesives

Phenolic-based adhesives are known for their exceptional heat resistance, making them suitable for extreme high-temperature label applications. They can withstand temperatures up to 300°C (572°F) without losing their adhesive properties. Phenolic adhesives are commonly used in industries such as automotive, aerospace, and oil and gas, where labels must endure harsh operating conditions.

Phenolic adhesives offer excellent chemical resistance and can withstand exposure to solvents, fuels, and lubricants. They also exhibit good resistance to UV light and moisture, ensuring that labels remain intact and legible in challenging environments.

Conclusion

When it comes to high-temperature label applications, choosing the right adhesive is crucial. Silicone-based adhesives are the most heat-resistant, capable of withstanding temperatures up to 315°C (600°F). Acrylic-based adhesives offer reliable performance at temperatures up to 150°C (302°F). For extreme high-temperature applications, phenolic-based adhesives provide exceptional heat resistance up to 300°C (572°F).

Consider the specific requirements of your application and the temperature range your labels will be exposed to when selecting the appropriate adhesive. By choosing the right adhesive, you can ensure that your high-temperature labels remain securely attached and legible, even in the most demanding environments.
