About Sealant Flexibility

Silicone Sealants

Made from silicone, these sealants are RTV (room-temperature vulcanizing).

Silicone Sealants with Material Certification

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

Mildew-Resistant Silicone Sealants

Resistant to mold and mildew, these sealants are well suited to high-humidity environments.

Self-Leveling Silicone Sealants

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

Self-Leveling Silicone Sealants
with Material Certification

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

Noncorrosive Silicone Sealants

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

Noncorrosive Silicone Sealants
with Material Certification

This sealant includes a material certificate with traceable lot number, test report, and product shelf life.

All-Weather Application Sealants

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

Self-Leveling Sealants

Thinner than non-sagging sealants, this sealant flows easily into cracks and has a smooth finish.

Sealants

Optically Clear Sealants

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

Caulking Tape

Press this adhesive-backed plastic tape into place for an immediate light-duty seal.

Non-Hardening Caulk

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

Removable Caulk

Make temporary waterproof seals that peel off when no longer needed.

Caulk

Glass Sealants

UV-Resistant Glass Sealants

These sealants don't degrade in sunlight.

Glass Sealants

Also known as glazing compounds, use these sealants to install glass in aluminum, steel, and wood framing.

Fire-Rated Glass Sealing Tape

Seal glass windows in metal and wood fire-rated doors.

Structural Glass Sealants

Make seals that support glass under heavy loads in equipment and buildings.

Glass Sealing Rope

Press this pliable rope into place to hold glass in window frames and seal leaks.

Electrical Insulating Varnish

Spray these abrasion- and wear-resistant coatings on motor winding wire, transformers, and other metal electrical parts to protect them from oils, chemicals, and moisture.

Fabricating and Machining

Electrical-Insulating Wire Rope Cutters

Insulated handles protect against shock from accidental contact with live electrical circuits. These cutters are tested to 1,000 volts to meet IEC 60900 and ASTM F1505.

Electrical-Insulating Rectangular Files

An insulated handle protects against shock from accidental contact with live electrical circuits. These files are tested to 1,000 volts to meet ASTM F1505.

Electrical-Insulating Half-Round Files

An insulated handle protects against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet ASTM F1505.

Electrical-Insulating Triangular Files

An insulated handle protects against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet ASTM F1505.

Adhesives

Urethane Structural Adhesives

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

Construction Adhesives for Dissimilar Materials

Bond glass and stone to drywall, treated lumber, and subfloors.

Silicone Potting Compounds

Ready-to-Use Silicone Potting Compounds

No mixing required—these potting compounds come ready to apply.

Two-Part Silicone Potting Compounds

Optically Clear Two-Part Silicone Potting Compounds

Clear enough to read through, this UV-resistant potting compound allows optimal light transmission for use with LEDs, solar cells, and fiber optics.
