Tube Epoxies | McMaster-Carr

For quick repairs, these epoxies begin to harden in 6 minutes or less. Epoxies are the strongest and most weather- and chemical-resistant structural adhesives.

The size listed is the combined total of the two parts.

DP100NS and 3501 are nonsagging, so they won't drip from vertical or overhead surfaces.

Ready-to-Use Silicone Potting Compounds

No mixing required --these potting compounds come ready to apply. Use them to encase electronic assemblies for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They're also known as RTV (room-temperature vulcanizing).

Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).
