Henkel LOCTITE EDAG 440 package EMI shielding coating

Henkel Adhesive Technologies · Material properties and interface engineering

Purpose: Package-shielding review needs coating, grounding and coverage comparisons beyond material conductivity.
Technical approach: LOCTITE EDAG 440 AS E&C is a nickel thermoplastic conductive coating applied/dried to form a shielding surface.
Scope of use: The named TDS chiefly covers equipment housings; confirm package substrate, solvent, thickness and grounding compatibility separately.
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
Typical shielding data have specimen/thickness conditions and do not guarantee package performance or EMC compliance. Check solvent-sensitive substrates and coverage/grounding gaps.
What to prepare
BLNKK suggests preparing bands, package/grounding geometry, substrates, thickness/coverage, coating/drying conditions and fixed-fixture shielding measurements.
Confirm with the supplier
First confirm availability and package suitability; discuss solvent/substrate, drying/adhesion, ground continuity and representative-specimen shielding validation.
Public evidence: The actual official TDS documents material, spraying and drying; housing use is not package qualification.
