Make seals that support glass under heavy loads in equipment and buildings. These sealants are also known as glazing compounds. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).

Joint compression/expansion tolerance indicates flexibility—the higher the value is, the more joint movement a sealant can sustain.

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.

Seal glass windows in metal and wood fire-rated doors. Also known as glazing tape, it has an adhesive back with a peel-off liner.

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

With chemical and metal additives that are picked up by X-ray machines and metal detectors, these sealants are designed to help you comply with Hazard Analysis and Critical Control Point (HACCP) programs in food-processing facilities. Their blue color means they’re also easily spotted and removed if a piece falls into your line. They’re unpalatable to rodents, so they’re often used to seal entry points such as windows, doors, and wall panels to keep out pests.

Also known as neutral cure, these sealants are noncorrosive and won't discolor copper, brass, or concrete. They’re structural sealants, meaning they combine excellent sealing properties and high flexibility with the mechanical strength of an adhesive—they can even join dissimilar materials. Made of silicone, their resistance to UV light, moisture, and both high and low temperatures makes them suitable for both indoor and outdoor use. These sealants are room-temperature vulcanizing (RTV), so they’ll begin to cure as soon as they’re exposed to air. They’re non-sagging and won’t drip from vertical or overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values, the more joint movement a sealant can sustain.
