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. 3M 730 UV is good for use between dissimilar materials and in environments with wide temperature fluctuation.

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

Butyl rubber has a sticky, gummy consistency.

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.

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.

The strongest submersible sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light. Sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.

Seal joints and gaps in concrete. These 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. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Repair equipment and vehicle windows with these sealants that are rated to withstand impact within three hours of application. They’re non-sagging, so they won't drip from vertical and overhead surfaces. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation. They’re crash tested and meet Federal Motor Vehicle Safety Standard 212 for windshield mounting.

Elongation indicates flexibility—the higher the value is, the more joint movement a sealant can sustain.

A primer is required. For best results use P591 for composites, glass, and fiberglass and P592 for aluminum, steel, and stainless steel.

This tape has a higher density than standard tape for a better seal between threads. Made of PTFE, it has a slippery surface that keeps threads from binding to make parts easy to assemble.

Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.

Prepare joints and surfaces to ensure proper sealant adhesion.

3M P592 primer cannot be sold to the listed regions due to volatile organic compound regulations.

Clean surfaces before applying sealant to promote bonding. Cleaners cannot be sold to the listed regions due to regulatory limits on VOCs (volatile organic compounds).
