- Silane coupling agent with methacrylate group and longer spacer chain than conventional product (KBM-503)
- 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.
