Important Notes

1.Sealing and Waterproofing

The drum lid must be tightly sealed! The lid should be tightened immediately after each use to prevent moisture from the air from entering.

It is recommended to fill the A component drum with dry nitrogen gas for protection (especially for large packages or frequent use).

The storage area floor should be dry to prevent corrosion of the drum bottom. Storage in the open air or under an open-sided shed is not recommended.

2.Fire Safety

Polyurethane raw materials are mostly organic chemicals and are flammable or combustible substances. The storage area must comply with fire safety regulations, and open flames are strictly prohibited.  Appropriate fire-fighting equipment (such as dry powder and carbon dioxide fire extinguishers) should be available.

They should be stored separately from strong oxidizing agents, acids, alkalis, and other chemicals.

3.”First-In, First-Out” Principle

Strict inventory management should be implemented to ensure that the batches produced first are used first, preventing product spoilage due to long-term storage.

4.Pre-treatment Before Use

Direct heating with open flames is prohibited! If heating is required to reduce viscosity, use a hot water bath, a hot air circulating oven, or a heated storage tank.

Thorough stirring is required before use! Especially for component B, prolonged standing may cause filler and pigment sedimentation or component separation. Stirring should be even and slow to avoid incorporating excessive air.

If component A crystallizes, it should be melted in a warm environment (such as an oven) at 50℃ ~ 60℃, and thoroughly and evenly stirred to ensure that all crystals are dissolved and mixed evenly before use. Local heating will lead to inconsistent performance.

5.Safety Precautions

The storage area should be well-ventilated to avoid inhaling vapors.

Wear appropriate personal protective equipment during operation, such as safety glasses, gloves (chemical-resistant), and work clothes.

If skin or eye contact occurs, immediately rinse with plenty of water and seek medical attention.

6.Transportation and Handling

Avoid direct sunlight, rain, and drastic temperature changes during transportation.

Handle with care to prevent damage to the packaging.

7.Compatibility

Mixing or storing A and B components from different manufacturers or different models is strictly prohibited. Even for the same type, different batches may have different ratios; a small-scale test should be conducted before using a new batch.

Simple Checklist

Is the storage temperature within the range of 15-25℃ (ideal) or 5-30℃ (acceptable)? Is the environment dry (humidity <70%)?

Is the container lid tightly sealed?

Is the storage location away from heat sources, open flames, and direct sunlight?

Is the “first-in, first-out” principle being followed?

Has the product been thoroughly stirred and preheated (if necessary) before use?

Are there any abnormalities in the packaging container, such as bulging or leakage?

Finally, a reminder: The most accurate storage requirements should always be based on the product’s instruction manual (MSDS/TDS). If there are deviations in storage conditions or if you have any doubts about product quality, please contact us for testing and confirmation. Correct storage is the first step in ensuring the stable quality of polyurethane products.
