Technical Details & Test Data

General Instructions

EV Protect 5008-A / 5008-B is a two-component material. Hand mixing may be difficult. It is recommended that an automated dispensing unit be used with dynamic mixer to mix material. Prior to use, stir the individual parts to ensure they are uniform and homogeneous. Mixing the 5008-A prior to use for 5-10 minutes is essential to achieve a consistent foam density and cell structure. Check the container bottom for sediment after mixing to ensure filler is mixed in. If an extended shutdown or break in production has occurred (> 1 hour) re-mix part A side prior to use. Note: Pail or Drum size containers may require longer mixing times. Surface must be clean, dry, and free from grease, oil, wax and other surface contaminates.
