The recommended re-evaluation/shelf life date is the length of time during which the product meets specifications when stored in accordance with recommended conditions. Beyond this date, it is recommended that the product not be used without further appropriate re-examination.
The recommended reevaluation dates for Landercoll® cellulose ethers and Accurate® VAE Re-dispersible polymer powder products are based on an ongoing stability study in which products are stored in commercial packaging in warehouses in Jinan, Shandong, China.
Temperature and humidity are monitored routinely, and the minimum and maximum temperature and humidity were 6 to 39°C and 5 to 100% respectively.
Storing products at temperature and humidity conditions outside of these ranges may shorten the time period for product reevaluation.
