Save
Stability: Shelf life in original container is 12 months from date of manufacture*
Storage conditions: room temperature (up to 25°C)
Remarks: The solid content and acid value from the date of production have been qualified
* All esters of 3-mercaptopropionic acid will be oxidized when in contact with air, which is why the effective content in the original PE packaging will decrease slightly and the acid value will increase;
The composition of this product is pentaerythritol mercaptopropionate, which is a mixture of mono-, di-, and tripentaerythritol esters. The degree of esterification is at least 3.8 as determined by the iodometric method. The registered CAS and EINECS numbers are the main components, and the measured content is more than 90% of pentaerythritol mercaptopropionate.
