Required Performance Water ResistanceAlkali ResistanceAdhesion
Features and Applications Filler DispersionCoating Additive
  • Silane coupling agent with ethylenediamine structure and longer spacer chain than conventional product (KBM-603)
  • Owing to the long spacer chain, improvement of hydrophobicity and flexibility can be expected.
  • Improvement of adhesiveness, alkali resistance and water resistance can be expected.

Water resistance test conditions: 40°C x 1 week


In the case of KBM-603, water is drawn into the interface, and adhesion is reduced after the water resistance test.
In contrast, KBM-6803 has a hydrophobic long-chain group, which prevents water from being drawn into the interface.
Thus, it is thought that water resistance will improve.
