ChemSet 217 Potting Silicone, 600 mL Cartridge

Description

The ChemSet 217 silicone is a one-part room-temperature-cure (RTV) potting silicone supplied in a 600 mL sausage cartridge for production dispensing. It is built for industrial encapsulation work where parts need a flexible, moisture-resistant barrier without heat cure or two-part mixing on the bench.

Where ChemSet 217 silicone works on the line

• Potting electronic enclosures, sensor housings, and small assemblies that see vibration or moisture exposure.
• Encapsulating connector backs, transformer windings, and PCB-mounted components where dielectric protection matters.
• Sealing seams on metal and plastic housings before paint or coating cycles.
• Bonding gasket or grommet hardware to substrates in HVAC, lighting, and equipment housings.
• Filling cavities in tooling and fixtures where a forgiving cured rubber is preferred over a rigid resin.

The 600 mL sausage form factor fits standard pneumatic and manual bulk dispensing guns, which makes it a fit for shops already running cartridge-format adhesives and silicones. Skinning behavior follows typical one-part RTV chemistry. The bead skins within minutes at room temperature and ambient humidity, with full cure depth building over 24 hours depending on bead thickness and conditions.

How ChemSet 217 silicone holds up in service

• Wide service temperature range typical of RTV silicone keeps the cured rubber stable across mixed environmental exposure.
• Cured silicone resists moisture ingress, ozone, UV, and dilute chemical contact.
• Stays flexible after cure to absorb vibration without cracking the bond line.
• Adheres to most clean metals, glass, ceramics, and many engineering plastics with proper surface prep.

Confirm substrate preparation before dispensing. Wipe surfaces clean and dry, gun the bead, tool if needed, and let the part rest for the required skin time before handling.
