Dow SE 4422 thermally conductive adhesive is gray in color with a fluidity of 1. 7 inches. The specific gravity of cured material is 2.2 and the NVC (Nonvolatile content) is 99.4%. Tack-free time at 25°C is approximately 11 minutes and the tensile strength is 740 psi. Dowsil SE 4422 will cure into a durable, low-stress elastomer with a noncorrosive by-product. This material is specifically designed to remove heat from electronic devices allowing them to operate more efficiently and increase reliability over the life of the device. Properties of the material such as high thermal conductivity, low thermal resistance and achieving a thin bond line thickness allows this product to effectively transfer heat away from the device.
Dowsil SE 4422 Thermally Conductive Adhesive Features and Benefits:

- Fast Tack-Free Time
- Good Adhesion
- Thermally Conductive
- UL 94 V-1 Recognized
The thermal conductivity of Dow SE 4422 is 0.9 W/mK and the unprimed adhesion, lap shear to aluminum is 206 psi. The moisture cure silicone adhesive is generally cured at room temperature in a range of 0 to 80 percent relative humidity. Greater than 90 percent of the adhesives full physical properties should be attained within 4 to 7 hours. It is not recommended to use the material for highly confined or deep section cured. It will generally cure approximately 0.25 inch per 7 days. Dow SE 4422 will provide unprimed adhesion to a variety of reactive metals, glass, ceramics, as well as laminates and plastics.
Before handling, reading and understanding the Dowsil SE 4422 Thermally Conductive Adhesive MSDS is strongly recommended. The silicone product is operational over a temperature range of – 45 to 200°C for long periods of time. Anything above or below the stated time may make the behavior of the material more complex, requiring additional test Low-temperature thermal cycling to conditions as low as -55°C may be possible for most products but needs to be verified for your parts assemblies. The products have not been tested nor deemed suitable for medical or pharmaceutical uses.
