·POSITION：Application → Common Question → Why is porcelain white silicone adhesive made with alcohol based crosslinking agents prone to yellowing?

Why does the color of the product gradually deepen during the storage of oxime cross-linking agent?
Date：2023/8/2 14:59:37  View：  【 Font Size：Big Medium Small 】  【CLOSE】

Mainly because the amino group in the oxime cross-linking agent will gradually turn yellow under the influence of temperature. VOS contains vinyl groups, which will accelerate the yellowing phenomenon. Therefore, the oxime cross-linking agent is easy to turn yellow in summer, especially VOS will turn yellow obviously after being stored for about 2 months.
