Safety notes

Request the current product-specific Safety Data Sheet and handling guidance before storage, mixing or application.

Review limits

Strength remains on hold because historical bag and TDS declarations differ and matched test methods/reports are missing.
The declared 12-month shelf life needs qualified storage conditions. Current SDS and complete application procedure are required.
