Sealants

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility. 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.

Urethane Structural Adhesives

Cartridge

Urethanes are the most flexible adhesives, so they bond dissimilar materials and damp vibration.

Some of these adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

Model Number 292—Do not require mixing.

Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.

Paste—Thicker than liquid adhesives but still spreadable—good for filling gaps and covering surfaces.

Submersible Sealants

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

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.

Sika Sikaflex Polyurethane Rubber

Cartridge

Sika Sikaflex sealants meet NSF/ANSI 61 safety standards for use with drinking water.

UV-Resistant Glass Sealants

These sealants don't degrade in sunlight. Also known as glazing compounds, use these sealants to install glass in framing. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, these sealants are RTV (room-temperature vulcanizing).

Optically Clear Sealants

Clear enough to read through, these UV-resistant sealants allow optimal light transmission for use with solar cells and fiber optics. Sealants are 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.

Structural Sealants


Cartridge	Sausage Pack

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.
