ZS-NJ-D901B RTV Silicone Adhesive Sealant
Description
The ZS-NJ-D901B RTV silicone adhesive sealant is composed of a one-part, room-temperature curing, ketoxime product. This product is semi-flowable, self-leveling, and won’t permeate into small gaps, allowing for a high sealing strength. It cures to an elastomer and offers an excellent resistance to thermal cycling, stress-changing, low and high temperatures. This product can maintain elasticity, stability and UV resistance for a long period at temperatures of -60～200℃. During curing, ketoxime is released, which is slightly corrosive to PC and copper materials. It conforms to EU RoHS and REACH standards.
Typical applications
- Water and moisture proof sealing, bonding of electronic components
- Protective potting of modules
- Fixing connectors on circuit boards
