Mix a small amount of water-based paint with this caulk to match the color of your surface.

Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

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

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

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

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

These sealants are marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Clean surfaces before applying sealant to promote bonding.

The textured finish matches concrete surfaces.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Prevent the edges of tape, signs, and graphics from peeling by sealing out water and debris.

Form flexible water-resistant seals on metal, plastic, and rubber joints in heating, ventilation, air conditioning, and refrigeration applications.

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, remaining pliable enough to self-heal and stop leaks before they start.

Make flexible, waterproof repairs to rips and tears in canvas, leather, and acrylic fabric.
