Electronic Grade Black Silicone Sealant, ZS-NJ-D901B

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 Technical specs
