Advantages
  • good reactivity
  • It is not necessary to add any catalyst
  • Due to an optimum pH-value of about 8 it facilitates for instance the hydrophobization process of defoamers
Other Applications

for the production of in-situ hydrohobized defoamers

Storage

we recommend storing the products in sealed containers in a dry, cool place, and removed from volatile organic substances.
our recommended use-by date is 24 months after date of manufacture. Product more than 24 months old should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.
