StarSoft EQC

StarSoft EQC is 85% active.

StarSoft EQC is non-flammable. The solvent package is a combination of DEG (CAS #11-46-6) and DPG (CAS #25265-71-8).

StarSoft EQC has a melting point of 21°C which allows for “Cold Prep” manufacturing.

StarSoft EQC is plant-derived. We are very proud that EQC is vegetable-based and, as it is made from cotton-feed (non-edible), it does not take away raw materials for food supplies.

Water Dispersibility Test Procedure

  1. Heat test softener to 40°C
  2. Heat DI water to 25°C
  3. Start agitation
  4. Add test softener
  5. Continue mixing holding temperature at 25°C for 10, 20, 30, and 60 minutes
  6. Filter solution through 200 mesh filter
  7. Check whether lumps appear
  8. If you see lumps on the sieve, the water dispersibility is no good
