Opening Agent K-2800

K-2800 is a milky white slow-rebound opening agent for the opening of slow-rebound sponges.


  Application

  1. It can significantly reduce the tension of the surface, promote the rupture of cell and increase the sponge opening rate.

  2. Not affect the foaming, smooth feel, even and delicate cells, no taste, and without the problem of oil-like seepage.
