How to store opened footwear adhesives and primers properly?

Hey there! As a supplier of footwear adhesives and primers, I've seen firsthand how important it is to store these products properly. Whether you're a small shoe repair shop or a large-scale footwear manufacturer, getting the storage right can save you a ton of money and headaches. In this blog, I'll share some tips on how to store opened footwear adhesives and primers to keep them in top-notch condition.

Why Proper Storage Matters

Before we dive into the storage tips, let's talk about why it's so crucial to store these products correctly. Footwear adhesives and primers are formulated with specific chemicals that can react to different environmental factors. If they're not stored properly, these chemicals can break down, leading to a loss of effectiveness. This means that your adhesives might not bond as well, and your primers might not provide the necessary surface preparation. In the long run, this can result in defective products, wasted materials, and unhappy customers.

General Storage Guidelines

First off, let's go over some general rules that apply to most footwear adhesives and primers.

Temperature Control

Temperature is one of the most critical factors when it comes to storing these products. Most adhesives and primers should be stored at a consistent temperature between 50°F and 80°F (10°C and 27°C). Extreme temperatures can cause the chemicals in the products to expand or contract, which can affect their performance. For example, if it's too cold, the adhesive might thicken and become difficult to apply, while high temperatures can cause it to dry out or become unstable.

Humidity

Humidity can also have a big impact on the quality of your adhesives and primers. High humidity can introduce moisture into the products, which can lead to clumping, mold growth, or chemical reactions. On the other hand, low humidity can cause the products to dry out too quickly. Aim to store your products in an environment with a relative humidity of around 40% to 60%.

Light Exposure

Exposure to light, especially sunlight, can break down the chemicals in adhesives and primers. UV rays can cause the products to degrade, change color, or lose their adhesive properties. To prevent this, store your products in a dark place or use opaque containers.

Ventilation

Proper ventilation is essential to prevent the buildup of fumes. Many adhesives and primers contain volatile organic compounds (VOCs) that can be harmful if inhaled in large quantities. Make sure your storage area is well-ventilated to keep the air fresh and safe.

Specific Storage Tips for Different Types of Products

Now, let's take a look at some specific storage tips for different types of footwear adhesives and primers.

Solvent-Based Adhesives and Primers

Solvent-based products are known for their strong bonding properties and fast drying times. However, they're also more sensitive to temperature and humidity changes.

• Seal the Container Tightly: After opening, make sure to seal the container tightly to prevent the solvent from evaporating. Even a small amount of evaporation can change the consistency of the adhesive or primer, making it less effective.
• Store Upright: Storing the containers upright can help prevent leaks and spills. It also ensures that the solvent is evenly distributed throughout the product.
• Keep Away from Flames and Sparks: Solvent-based products are flammable, so it's crucial to store them away from any sources of ignition.

Water-Based Adhesives and Primers

Water-based products are more environmentally friendly and have lower VOC emissions. However, they're more prone to freezing and microbial growth.

• Protect from Freezing: Water-based adhesives and primers can freeze at low temperatures, which can damage the product. If you live in a cold climate, make sure to store these products in a heated area.
• Check for Mold Growth: Since water is the main component, these products can be a breeding ground for mold and bacteria. If you notice any signs of mold, such as a musty smell or discoloration, discard the product immediately.

Hot Melt Adhesives

Hot melt adhesives are solid at room temperature and become liquid when heated. They're known for their fast bonding and high strength.

• Keep in a Dry Place: Moisture can cause hot melt adhesives to degrade or form clumps. Make sure to store them in a dry environment to maintain their quality.
• Avoid Overheating: While hot melt adhesives need to be heated to be applied, overheating can cause them to break down. Follow the manufacturer's instructions for heating and storage.

Storing Opened Containers

Once you've opened a container of adhesive or primer, it's important to take extra care to keep it in good condition.

Use a Sealable Container

If the original container doesn't have a good seal, transfer the product to a sealable container. This will help prevent air, moisture, and contaminants from getting in.

Label the Container

Label the container with the date of opening and the product name. This will help you keep track of how long the product has been open and ensure that you use it before it expires.

Store in Small Quantities

If you don't need to use a large amount of adhesive or primer at once, consider storing it in smaller containers. This will reduce the amount of air exposure and help keep the product fresh for longer.
