Required Performance AdhesionWater ResistanceAlkali Resistance
Features and Applications Filler Surface TreatmentPrimerCoating Additive
  • Silane coupling agent with epoxy group and longer spacer chain than conventional product (KBM-403)
  • Owing to the long spacer chain, improvement of hydrophobicity and flexibility can be expected.
  • Improvement of adhesiveness, high filler filling, flexibility of cured material, alkali resistance, water resistance can be expected.

Product Information

Features and Resulting Properties

Improved hydrophobicity (lipophilicity) ⇒
Improved resin compatibility

Adhesion Test of Glass/Epoxy Resin Interface

Test Method
    1. ① A 1% aqueous solution is applied to a glass substrate.
    2. ② A cured material (EPIKOTE 828 [epoxy resin made by Mitsubishi Chemical Corporation]/triethylenetetramine) is prepared and adhesive strength is tested.

*Adhesive strength is calculated against a standard of 100 (untreated glass).

KBM-403:
3-Glycidoxypropyl trimethoxysilane
