About Sealant Flexibility
More
Silicone Sealants
Made from silicone, these sealants are RTV (room-temperature vulcanizing). They’re non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.
Sealants that cannot be sold outside the United States are restricted due to chemical regulations and/or product labeling requirements.

Mildew-Resistant Silicone Sealants
Resistant to mold and mildew, these sealants are well suited to high-humidity environments. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.
Silicone sealants that cannot be sold to Canada are restricted due to product labeling requirements.

Low-Outgassing Silicone Sealants
Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Made of silicone, they’re RTV (room-temperature vulcanizing), so they’ll fully harden at room temperature.
Elongation indicates flexibility—the higher the value is, the more a sealant can stretch.
Sealants that begin to harden in 26 min. are less likely to trap contaminants than those that take longer to harden.

Electrical-Insulating Scissors for Wire Cutting and Stripping
Insulated handles protect against shock from accidental contact with live electrical circuits. These scissors are tested to 1,000 volts to meet IEC 60900 and ASTM F1505. Also known as electricians' shears, they have a notch for stripping wire.
