How Should I Store My Thermal Gap Filler Gel?

Proper storage helps maintain the dispensing, curing and thermal performance of a thermal gap filler gel before use. Because storage requirements can vary between one-part and two-part formulations, always follow the Technical Data Sheet (TDS) for the specific product.

To ensure the optimal performance and longevity of your thermal gap filler gel, follow these storage guidelines:

1. Check the Product-Specific Storage Temperature

Store in a cool, dry place with a stable temperature, ideally between 15°C ~ 25°C (59°F ~ 77°F). Avoid extreme temperatures (both hot and cold), as heat can cause separation or degradation, while cold may harden or crack the gel.

2. Keep the Original Package Properly Closed

Keep unused material in its original container or cartridge and close or seal it properly after use where applicable.

This helps reduce contamination and protects the material before dispensing. For two-part gap fillers, Part A and Part B should remain separated until the material is intentionally dispensed and mixed at the specified ratio.

3. Avoid Unnecessary Pressure on the Package

Cartridges and containers should be stored and handled in a way that prevents unintended pressure or material discharge before use.

4. Protect the Material from Direct Sunlight

Store in a dark place or in the original opaque container to protect from UV/light exposure, which may degrade the material.

5. Follow the Specified Shelf Life

Check the manufacturer's expiration date or shelf-life recommendations (typically 1 ~ 2 years if unopened, shelf life of the product is 6 months after date of shipment). Use older stock first and inspect for changes in texture or separation before use.

6. Check the Material Before Use

Before dispensing material that has been stored for an extended period, inspect the package and material condition according to the product instructions.

Do not automatically remix, dilute or otherwise rework material that appears abnormal. For a two-part liquid gap filler, follow the specified A/B mixing ratio and dispensing procedure rather than manually mixing the components before use.

7. Follow Manufacturer Guidelines

Always review the product’s datasheet for specific storage instructions, as formulations vary (e.g., silicone-based vs. non-silicone).

By adhering to these steps, you’ll maintain the thermal gap filler gel efficacy for efficient thermal management.
