CW2400 — Two-part silver-filled conductive epoxy
CW2400 from CHEMTRONIC is a two-part, silver-filled conductive epoxy (CircuitWorks) for prototyping, repair, and general conductive bonding. The product comes in a blister pack with a 7g adhesive syringe (Part A) and a 7g hardener syringe (Part B). The mixed material provides approximately five minutes of working time and achieves maximum conductivity and strength after 24 hours.
Technical Description
CW2400 is formulated as an epoxy/hardener system with a high silver fill ratio to ensure low volume resistivity and good thermal conductivity. The mixing ratio is 1:1 by weight or volume. The product's properties regarding cure time, pot life, and temperature range are documented by the manufacturer.
Typical Applications
The following applications are specified by the manufacturer and can be used with CW2400:
- Conductive connections between heat-sensitive components
- Solderless surface mount connections
- Repair of circuit traces
- Static dissipation and grounding
- Solder repair
- Conductive structural bonds
Application and Curing Instructions
- Mixing ratio: 1:1 by weight or volume; mix thoroughly for 2 minutes.
- Working time: approximately 5 minutes of working time after mixing.
- Pot life: 8–10 minutes at 75°F (25°C) after mixing.
- Room temperature cure: Can cure at room temperature ≥75°F (25°C) in approximately 4 hours; maximum conductivity and strength are achieved after 24 hours.
- Optional rapid cure: For fastest curing and best electrical properties, post-curing at 150–250°F (65–121°C) for 5–10 minutes is recommended.
- Cleaning: The manufacturer recommends cleaning with Chemtronics Electro-Wash or Pow-R-Wash before application.
- Storage: Store below 77°F (25°C); shelf life 9 months.
