Polydimethylsiloxane (SE 9189 L White) is a one-part, flowable silicone adhesive formulated for electronic assembly, sealing, and vibration-dampening applications.
It cures at room temperature to form a soft, low-stress elastomer with excellent adhesion, flame resistance, and controlled volatility — ideal for sensitive electronic and industrial components.
This fast tack-free, solvent-free adhesive offers easy dispensing, faster in-line processing, and no need for oven curing, with optional mild heat acceleration for improved production efficiency.
The cured material provides reliable bonding and stress relief on printed circuit boards, electrical modules, and sensitive assemblies, while meeting UL 94 V-0 flame resistance standards.
Applications
• Parts fixing on circuit boards
• Vibration dampening in electronic modules
• Sealing of components and housings
• Protective coating for sensitive electronic parts
• Assembly bonding requiring soft, stress-relieving materials
