Self-Leveling Silicone Rubber Sealants
 |  |
Cartridge | Tube |
Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish. Made from silicone rubber, 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.

Self-Leveling Oil- and Fuel-Resistant Sealants
| |
Cartridge | Tube |
Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
Elongation and joint expansion/compression tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint expansion/compression tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.
Cannot Be Sold to California—Sealants that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

Self-Leveling Chemical-Resistant Sealants
|  |
Cartridge | Can |
Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to sulfuric acid, hydrochloric acid, nitric acid, gasoline, and oil. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.
Cannot Be Sold To—Sealants that cannot be sold to the regions listed exceed local regulatory limits on VOCs (volatile organic compounds).
