Product Description
Dowsil EA-4100 Needle-Dispensed Adhesive for Electronics Encapsulation
Basic Properties
Dowsil EA-4100 is a one-part, moisture-cure white paste adhesive with density 1.42 g/cm³ (cured), Shore A hardness 45, and elongation at break 250%. Designed for needle dispensing in electronics encapsulation, operable from -45°C to 200°C.
Product Description
EA-4100 cures via ambient moisture-triggered condensation, eliminating heating systems (tack-free in 9 min@25°C). 260 g/min extrusion rate suits automated dispensing, while 1 cm slump enables uniform filling. Volume resistivity and dielectric strength data not provided in TDS.

Application Scenarios
  • Power Module Potting: Encapsulates IGBT modules. 250% elongation absorbs thermal cycling stress, compliant with MIL-STD-810G thermal shock.
  • Automotive Sensor Bonding: Adheres O₂ sensor connectors. -45°C flexibility prevents cracking, implemented in assembly lines.
  • LED Driver Sealing: Edge-seals outdoor PCBs. Moisture-cure properties suit high-humidity environments, achieving IP67 rating.
  • Chip Reinforcement: Secures processor peripherals. 45 Shore A hardness balances impact resistance & stress relief, used in Huawei base stations.
