Sticking to the Right Consistency: How Temperature Influences Industrial Glue Viscosity and Storage

In the world of industrial adhesives, failure to stick is not an option. The glue’s viscosity plays a pivotal role in creating an optimal bond. The one element that affects a glue’s viscosity is the temperature. Temperature has the power to make or break the performance of these sticky substances.

Understanding Viscosity in Industrial Glues

Adhesives play a critical role in almost every type of manufacturing, from epoxy in composite aircraft parts to sealing electronic components. 

The consequences of getting adhesive viscosity wrong can lead to structural failures or product malfunctions. Viscosity is the actual measurement of a fluid’s resistance to flow. It describes how thick or thin a liquid is and directly impacts how it spreads and adheres to surfaces.

The Crucial Role of Temperature in Glue Viscosity

As with most liquids, the viscosity of glue decreases as the mercury rises. Industries that rely on adhesives must carefully measure viscosity to ensure consistency. If the adhesive becomes too thin, it can lead to inadequate bonding and gradual deformation under load. If it is too thick, it can prevent proper adhesion and coverage, leading to a potential failure. 

When calculating viscosity and a fluid’s flow properties, the measurement unit is in centipoise (cP). For example, water has a cP of 1 at 20°C. For comparison, the viscosity of Elmer’s glue is 2,311 cPs. 

An adhesive chart is a tool engineers use to correlate temperature with the viscosity of glue, ensuring that each batch meets strict quality standards. 

Temperature’s Impact on Glue Viscosity

Temperature control for improved flow is critical for mass production of adhesive products or when dispensing them as part of a process. 

What Happens to Glue as Temperature Changes

At higher temperatures, the excess heat can cause the adhesive to become too thin. If the ambient temperature is too cold, the glue’s viscosity increases and can even solidify. 

If the adhesive is outside of the acceptable temperature range, the wrong viscosity can slow or halt production from the adhesive flowing too fast or too slowly. Temperature is an issue with larger quantities, such as 55-gallon drums of glue.

Scientifically speaking, higher heat provides energy to the molecules within the adhesive, causing them to move more rapidly and resulting in a thinner consistency. Cold reduces molecular energy, causing molecules to move less and stick together, increasing resistance to flow.

Maintaining adhesives at the correct temperature becomes a challenge in storage areas without environmental controls.

Challenges of Storing Industrial Glue 

Besides temperature, the flow properties of adhesives are also subject to the size and shape of the storage container, with larger volumes being more susceptible to temperature variations.

Best Practices for Industrial Glue Storage

To maintain the effectiveness, longevity, and viscosity of glue, users must follow several best practices for its storage, such as:

• Maintain Consistent Temperatures: Store the glue in a controlled environment where the temperature is consistent. Powerblanket IBC tote warmers can maintain the temperature of 275-gallon totes of glue.

• Monitor Temperature Regularly: Install temperature monitoring systems to check the storage conditions.
• Understand the Glue’s Specifications: Refer to the manufacturer’s specifications or an adhesive chart to know the optimal storage conditions for the specific type of adhesive.
• Avoid Direct Sunlight and Moisture: Store the glue in a place away from direct sunlight and moisture, as these factors can initiate premature curing or degrade the adhesive.
• Use Proper Containers: Store the glue in the correct type of container. Seal the container to prevent contamination and exposure to air.
• Rotate Stock: Practice the first-in, first-out (FIFO) inventory method to use the oldest products first and keep the stock fresh.
• Measure Viscosity Periodically: Conduct regular checks to measure viscosity and ensure that the glue is within the desired range.
• Follow Safety Guidelines: Many industrial adhesives have a hazardous material classification. Always adhere to safety guidelines for storing hazardous materials.
• Train Staff: Ensure that all staff handling the glue are trained in proper storage and handling procedures to prevent accidents and product waste.
• Prepare for Seasonal Changes: Have a plan for adjusting storage conditions in response to seasonal temperature fluctuations.
• Invest in Quality Equipment: Use high-quality storage and heating equipment, like Powerblanket IBC tote warmers, to maintain the proper temperature, especially for uncured adhesives with sensitive flow properties.

Implementing these best practices reduces waste and increases efficiency.

Preparing for Temperature-Related Challenges

Adhesive manufacturers should have a strategy in place to deal with seasonal shifts and unexpected temperature changes. Anticipate freezing weather or heatwaves that could impact adhesive properties in storage or production areas.

Innovative Solutions for Temperature Regulation

Powerblanket provides innovative heating solutions designed to maintain optimal temperature conditions for IBC (Intermediate Bulk Container) totes of various sizes. The IBC tote warmers are engineered to deliver uniform heat, preventing hot and cold spots and ensuring consistent glue viscosity.

The Interplay Between Temperature and Glue Viscosity

The relationship between temperature and glue viscosity is both intricate and integral. Too high or too low viscosity can sabotage the adhesive’s performance, leading to product failure and financial losses.
