Why Proper Storage of Solvent-Based Adhesives Matters

In this guide, we’ll explore best practices for storing different solvent-based adhesives to ensure they remain effective and safe for use. When it comes to adhesives, proper storage is crucial to maintaining their effectiveness and extending their shelf life. Solvent-based adhesives, commonly used in various industries, are particularly sensitive to environmental conditions. Improper storage can lead to reduced performance, premature curing, or even hazardous situations.

 Polyurethane (PU) Adhesives

• Storage Temperature: Store in a cool, dry place, ideally between 5°C and 25°C (41°F and 77°F).

• Moisture Sensitivity: PU adhesives are highly sensitive to moisture. After opening, it’s recommended to displace the air in the container with an inert gas like nitrogen to prevent moisture contamination.

• Container Sealing: Misc Industrial Adhesives CTG also points out that for PU adhesives, it is crucial to ensure the container is tightly sealed to prevent solvent evaporation and contamination.

 Neoprene Adhesives

• Storage Temperature: Keep in a cool, dry place between 10°C and 30°C (50°F and 86°F).

• Solvent Evaporation: Neoprene adhesives are solvent-based and can lose effectiveness if solvents evaporate. Always store in tightly sealed containers.

• Humidity Control: While less sensitive to moisture than PU adhesives, it’s still advisable to store in a dry environment to maintain optimal performance.

 Spray Adhesives

• Storage Temperature: Store in a cool, dry place, ideally between 15°C and 25°C (59°F and 77°F).

• Flammability: Spray adhesives often contain flammable solvents. Keep away from heat sources and open flames.

• Container Integrity: Ensure the can is tightly sealed to prevent solvent loss and maintain pressure.

 Contact Adhesives

• Storage Temperature: Keep in a cool, dry place between 10°C and 25°C (50°F and 77°F).

• Solvent Evaporation: Contact adhesives are sensitive to air exposure. Always seal containers tightly after use to prevent solvent evaporation.

• Shelf Life Management: Implement a First In, First Out (FIFO) system to use older stock first and maintain product effectiveness.Redwood UK

 Water-Based PU Adhesives

• Storage Temperature: Store in a cool, dry place between 5°C and 25°C (41°F and 77°F).

• Moisture Sensitivity: Despite being water-based, these adhesives can still be sensitive to extreme humidity levels. Store in a stable environment to maintain performance.

• Container Sealing: Ensure containers are tightly sealed to prevent contamination and drying out.

Best Practices for Storing Solvent-Based Adhesives

Proper storage of solvent-based adhesives is essential to ensure their longevity and performance. By following these guidelines:

• Temperature Control: Store adhesives within the recommended temperature ranges to prevent degradation.

• Sealing Containers: Always ensure containers are tightly sealed to prevent solvent evaporation and contamination.

• Moisture and Humidity Management: Store in environments with controlled humidity to prevent premature curing or degradation.

• Safety Precautions: For flammable adhesives, store away from heat sources and open flames.

Implementing these practices will help maintain the effectiveness and safety of your adhesives, ensuring they perform optimally when needed.
