Matters needing attention in storage and use of polyurethane adhesive

1. Moisture-proof: Polyurethane Adhesive is a material with strong moisture absorption, so it should be stored in a dry and ventilated place to avoid a wet environment and moisture intrusion. It is suggested that the polyurethane adhesive stored in a humid environment should be dried before use to ensure its quality and effect.

2. Sun protection: polyurethane adhesives are prone to aging and embrittlement in the sun, so closed storage containers should be selected and placed in a dark place to avoid direct sunlight.

3. Fire protection: polyurethane adhesive is not resistant to high temperatures, so it should be forbidden to contact with fire sources during storage to avoid fire. It is recommended that a storage container with good fire resistance be chosen, and the storage environment be well-ventilated to avoid explosions caused by gas accumulation. ‌

4. Suitable temperature: the storage temperature should be controlled between 10℃ and 25℃, and high temperature will make the polyurethane adhesive physically change and lose its adhesiveness.

5. Sealing: polyurethane adhesive should be stored in strict sealing during storage to avoid air and impurities from entering.

Precautions for use:

1. The sealed polyurethane adhesive should avoid vibration and collision during handling, so as not to damage the package and cause leakage.

2. Check whether the package is in good condition before use, and replace it if it is damaged.

3. Polyurethane adhesive should be used as soon as possible after unsealing, and the unused part can be stored for a short time under suitable conditions.

4. It is not recommended to use polyurethane adhesive that has been opened for too long.

5. It is forbidden to use unqualified or expired polyurethane adhesive.
