Storage and Shelf Life Information
  • ChopVantage® HP 3786 should be stored in a dry area with ambient temperature and relative humidity, optimally from 20°C to 25°C and between 50% and 70%, respectively.
  • Protect product from all sources of water at all times.
  • A First-In-First-Out (FIFO) stock control system is recommended to minimize the influence of storage conditions.
  • Prior to use, products should be conditioned in the work area for a minimum of 24 hours.
  • If contents of a package unit are partially used, the unit should be closed until the next use.
  • With proper storage, there are no known limitations on the shelf life of the product.
  • To insure optimal performance, retesting is recommended for products stored more than three years from the initial production date.
