As a trusted supplier of solvent based laminating adhesives, I understand the importance of proper storage. These adhesives are widely used in various industries due to their excellent bonding properties and versatility. However, improper storage can lead to a range of issues, from reduced adhesive performance to safety hazards. In this blog post, I'll share some essential guidelines on how to store solvent based laminating adhesives effectively.
Understanding the Nature of Solvent Based Laminating Adhesives
Solvent based laminating adhesives consist of a resin dissolved in a solvent. The solvent evaporates during the drying process, leaving behind a strong bond between the substrates. These adhesives are known for their fast drying times, high bond strength, and good chemical resistance. However, the solvents used in these adhesives are often flammable and volatile, which means they require special handling and storage.
Storage Conditions
Temperature
One of the most critical factors in storing solvent based laminating adhesives is temperature. Most adhesives have a recommended storage temperature range, typically between 5°C and 30°C (41°F and 86°F). Storing adhesives outside of this range can have several negative effects.
If the temperature is too low, the adhesive may thicken or even solidify. This can make it difficult to mix and apply, and it may also affect the adhesive's bonding properties. On the other hand, if the temperature is too high, the solvent may evaporate too quickly, leading to a change in the adhesive's viscosity and potentially reducing its shelf life.
To maintain the proper temperature, store the adhesives in a climate - controlled area. Avoid storing them near heat sources such as radiators, furnaces, or direct sunlight. If you're storing adhesives in a warehouse, consider using temperature - monitoring devices to ensure that the storage conditions remain within the recommended range.
Humidity
Humidity can also have an impact on solvent based laminating adhesives. High humidity can cause moisture to penetrate the adhesive, which may lead to the formation of bubbles or a decrease in bond strength. It can also promote the growth of mold and bacteria, which can contaminate the adhesive.
Ideally, the storage area should have a relative humidity of less than 60%. You can use dehumidifiers to control the humidity levels in the storage space. Additionally, make sure the storage containers are tightly sealed to prevent moisture from entering.
Ventilation
Proper ventilation is essential when storing solvent based laminating adhesives. Since the solvents are volatile, they can release fumes into the air. These fumes can be harmful if inhaled, and they can also create a fire hazard.
Store the adhesives in a well - ventilated area, such as a storage room with exhaust fans. The ventilation system should be designed to remove the fumes from the storage area and prevent them from accumulating. It's also important to avoid storing large quantities of adhesives in a small, enclosed space.
Storage Containers
The choice of storage containers is also crucial. Use containers that are made of materials that are compatible with the adhesive and the solvent. For most solvent based laminating adhesives, metal or plastic containers are suitable.
Make sure the containers are tightly sealed to prevent the solvent from evaporating and to keep out moisture and contaminants. Check the containers regularly for any signs of damage, such as cracks or leaks. If a container is damaged, transfer the adhesive to a new, undamaged container immediately.
Safety Precautions
Fire Safety
As mentioned earlier, the solvents in solvent based laminating adhesives are flammable. Therefore, fire safety is of utmost importance. Store the adhesives away from open flames, sparks, and other sources of ignition.
Keep fire extinguishers nearby and make sure they are suitable for extinguishing flammable liquid fires. Train your employees on fire safety procedures and make sure they know how to use the fire extinguishers properly.
Personal Protective Equipment (PPE)
When handling and storing solvent based laminating adhesives, employees should wear appropriate personal protective equipment. This includes gloves, goggles, and respirators. Gloves will protect the hands from direct contact with the adhesive, while goggles will prevent the adhesive from splashing into the eyes. Respirators are necessary to protect the lungs from inhaling the fumes.
Shelf Life
All solvent based laminating adhesives have a limited shelf life. The shelf life is typically indicated on the product label. It's important to follow the recommended shelf life guidelines and use the adhesives before they expire.
Using expired adhesives can lead to poor bonding performance, such as delamination or reduced bond strength. Keep track of the expiration dates of your adhesives and rotate your stock regularly to ensure that you use the oldest adhesives first.
