Shin-Etsu KBM-403 epoxy silane coupling agent

Shin-Etsu Chemical · Material properties and interface engineering

Purpose: Moisture-related adhesion comparisons need the actual inorganic surface and resin formulation.
Technical approach: KBM-403 is an epoxy-functional silane; Shin-Etsu describes glass-fiber/resin coupling and surface modification.
Scope of use: Consider resin addition or surface modification, validating the specific package formulation, filler and metal interfaces.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Water-resistance/adhesion positioning does not establish MSL/reflow qualification or repair existing package delamination.
What to prepare
BLNKK suggests surface, resin/filler, addition/treatment and cure history alongside dry/wet adhesion and reflow results.
Confirm with the supplier
Confirm dosage, solvent/hydrolysis/treatment, storage/safety and compatibility using formulation-specific specimens.
Public evidence: The named selection guide identifies epoxy functionality, additive use and glass-fiber/resin interfaces.
