Required Performance AdhesionAlkali ResistanceWater Resistance
Features and Applications Primer TreatmentCoating AdditiveFiller Surface Treatment
  • Silane coupling agent with vinyl group and longer spacer chain than conventional product (KBM-1003)
  • Owing to the long spacer chain, improvement of hydrophobicity and flexibility can be expected.
  • Improvement of high filler filling, flexibility of cured material, alkali resistance, water resistance can be expected.

* Formulation polymer: curing agent = 100:5 Curing agent = tetrabutoxytitanium
Tack-free is confirmed by finger touch
1) Erosion of coating film confirmed by 10% NaOH solution

KBM-1083 Application Data

Size of steric hindrance around the alkoxysilyl group
n=2 > n=8

* Relaxation of steric hindrance by long-linked chains improves reactivity of hydrolytic condensation of alkoxysilyl groups and improves curability

Improved alkali resistance by introduction of octyl group (a hydrophobic group)
