Cyanoacrylate adhesives have a short shelf life. Date-stamped containers help to ensure that the adhesive is still viable. One manufacturer supplies the following information and advice: when kept unopened in a cool, dry location such as a refrigerator at a temperature of about 55 °F (13 °C), the shelf life of cyanoacrylate will be extended from about one year from manufacture to at least 15 months. If the adhesive is to be used within six months, it is not necessary to refrigerate it. Cyanoacrylates are moisture-sensitive, and moving from a cool to a hot location will create condensation; after removing from the refrigerator, it is best to let the adhesive reach room temperature before opening. After opening, it should be used within 30 days. Open containers should not be refrigerated.[26] Another manufacturer says that the maximum shelf life of 12 months is obtained for some of their cyanoacrylates if the original containers are stored at 35 to 40 °F (2 to 4 °C).[27] User forums and some manufacturers say that an almost unlimited shelf life is attainable by storing unopened at −4 °F (−20 °C), the typical temperature of a domestic freezer, and allowing to reach room temperature before use.[28] Rechilling an opened container may cause moisture from the air to condense in the container, however, reports from hobbyist suggest that storing in a freezer can preserve opened cyanoacrylate indefinitely.
As cyanoacrylates age they polymerize, become thicker, and cure more slowly. They can be thinned with a cyanoacrylate of the same chemical composition with lower viscosity.[29] Storing cyanoacrylates below 0 °F (−18 °C) will nearly stop the polymerization process and prevent aging.
ומדף נתונים טכנייםש ל לוקטייט:
חיי מדף של 21 חודשים בטמפרטורות בין 36-46 פרנהייט שזה קר מאוד (בין 0 ל 8 צלזיוס)
ואותם 21 חודשים ב 68 פרנהייט שזה גם לא ממש חם...(20 צלזיוס)
אקיצר - עמו עם יין - טמפ החדר שלנו בארץ חמה מדיי גם לדבק
נשמע שמקרר במגבלות שמצויינות למעלה הוא הפתרון
ובכלל לא לרכוש סטוקים...
