- EV Protect 4006 SFR is generally dispensed using a high speed dynamic mixer head directly into the battery module.
- The low viscosity liquid is easily able to flow and self level at the bottom of the enclosure.
- Once leveled, the material will foam and rise to approximately 5 times volumetric expansion.
- After rising, the foam will crosslink and cure creating a semi-structural interconnected foam that encapsulates all components within the module.
- In the event of a thermal event, the foam will absorb, isolate, and insulate the cells to mitigate thermal propagation.
- EV Protect 4006-A SFR / 4006-B SFR 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 4006-A-SFR prior to use for 5 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 produc tion 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.

- Hand Mixing Instructions for Foams
- Per the stated mix ratio, measure out (either by weight or volume) the appropriate portions of Part A and Part B as into a flat sided container.
- The mixing container should be larger than the amount of total material being mixed to allow for vigorous mixing. For example, for 75 grams of total material we suggest a minimum size of 150 ml container for mixing. For larger amounts, adjust container size appropriately.
- Generally it’s recommended to add the higher density part into the flat sided mixing container first and then add the other part gently on top of the first part.
- This helps limit pre-reaction of the materials to just the interphase. Scrape the side and bottom of the individual parts container’s to ensure nearly all the measured materials are added to the mixing container.
- Start timer and immediately mix vigorously for 20-30 seconds with a spatula or flat sided stir stick. Thoroughly scraping the sides and bottom of cup while mixing. Mixed material should be homogeneous and uniform in appearance.
- At end of mixing time, immediately pour mixed material into mold.
- Immediately clean all tools used in preparations that you wish to reuse with solvent.
