Sealants that cannot be sold to the regions listed are restricted by local chemical regulations, including limits on VOC (volatile organic compounds).

Clear enough to read through, this UV-resistant sealant allows optimal light transmission for use with solar cells and fiber optics. Apply it in cold temperatures, on wet surfaces, and even through running water. The sealant is non-sagging, so it won't drip from vertical and overhead surfaces. It cannot be sold to the regions listed due to local regulatory limits on VOC (volatile organic compounds).

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. This sealant is good for use between dissimilar materials and in environments with wide temperature fluctuation.

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. 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. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Also known as Torr Seal, this sealant forms a rigid bond to seal leaks on vacuum systems and components.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re thicker than most non-sagging sealants, so they can be used in vertical joints up to 1/2" wide. They cannot be sold to California because they exceed local regulatory limits on VOCs (volatile organic compounds).

Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
