main purpose of the product
  It is suitable for coatings, inks, sealants, greases, cosmetics, cleaning agents, bronzing materials, pigments, organic synthetic materials and replacing gaseous silica

 
usage method
The product does not need to prepare pre gel, and can be added at the grinding stage
It can also achieve good dispersion effect at the bottom shear condition
Of course, high shear dispersion and proper extension of the dispersion time will result in higher efficiency
There is no need to add polar activator to bp-138

The addition amount of bp-138 in the system is generally 0
