Low-temperature hot melt adhesive for diapers should be stored in a dry environment between 10℃ and 30℃, avoiding high temperatures, humidity, and direct sunlight. Ensure the packaging is sealed tightly to maintain its low-temperature application performance and chemical stability.
Due to its special formulation, this type of adhesive is sensitive to storage conditions. Improper storage may cause the adhesive to harden, absorb moisture, or age prematurely, affecting its melting state and bonding effect during production.
Temperature Control: The storage environment temperature should be strictly controlled between 10℃ and 30℃. Temperatures that are too low (e.g., below 5℃) will make the adhesive brittle, affecting melting uniformity; temperatures that are too high may cause pre-crosslinking or softening and clumping, especially weakening its core advantage of "low-temperature melting."
Humidity Management: The relative humidity is recommended to be controlled between 40% and 60% to prevent the hot melt adhesive from absorbing moisture. Moisture entering the adhesive can easily cause bubbles and splattering during heating, resulting in uneven coating or even nozzle clogging.
Avoid Light and Contamination: Avoid direct sunlight or proximity to heat sources (such as radiators or ovens) to prevent localized overheating and performance degradation. Also keep away from strong acids, strong alkalis, and other corrosive chemicals to prevent cross-contamination.
Packaging Integrity: Always seal the packaging after use. Unused adhesive blocks should be returned to the original packaging bag and tightly sealed to prevent air and moisture intrusion. Vacuum sealing or storage with a desiccant is recommended.
