Product Description
DOWSIL™ SE 9186 Black, Clear or White Adhesive is a one-part, moisture-curing silicone adhesive-sealant that cures at room temperature to a soft, low-stress elastomer. Formulated with controlled silicone volatility and a flowable, self-leveling consistency, this solventless adhesive is engineered specifically for sealing electronic equipment and fixing parts on circuit boards. Its fast tack-free time helps accelerate in-line processing without the need for curing ovens, enhancing overall manufacturing throughput.
Key features
- Fast room temperature cure: Tack-free in 8 minutes, enabling faster in-line processing without ovens while allowing for heat acceleration if desired.
- Flowable and self-leveling: Easily fills gaps and levels itself after dispensing, making it ideal for complex circuit board geometries.
- Controlled volatility: Reduced potential for silicone volatiles protects sensitive electronic modules and components.
Applications / Suitable for
- Sealing of electronic equipment and modules
- Parts fixing on circuit boards
- Sealing against potential stress cracks
