Mildew-Resistant Silicone Sealants

Resistant to mold and mildew, these sealants are well suited to high-humidity environments. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).
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.
Sealants that cannot be sold to Canada are restricted by product labeling requirements.

Epoxy Potting Compounds


Encase electronic assemblies in a layer of epoxy for protection from dust, chemicals, moisture, mechanical shock, and vibration. The strongest of the potting compounds, epoxies are rigid and wear resistant. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. All require a mixer nozzle and gun to dispense.

Ready-to-Use Silicone Potting Compounds

No mixing required --these potting compounds come ready to apply. Use them to encase electronic assemblies for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They're also known as RTV (room-temperature vulcanizing).
Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

Heavy Duty Optically Clear Light-Activated Coatings for Electronics

Clear enough to read through, this coating allows optimal light transmission for use with LEDs, solar cells, and fiber optics. Thinner than potting compounds, it flows easily into small spaces between electrical components. The coating requires an ultraviolet curing lamp to reach full strength. Dispense with a gun (sold separately).

Footwear Repair Adhesives
Repair rips, split seams, and detached soles to stop leaks in shoes, boots, and waders. These polyurethane adhesives create a strong, flexible seal that keeps water out, so they’re also used to coat seams. Use on leather, plastic, and rubber. They fully harden in 10 hours and dry clear.

Shoe and Boot Protective Epoxy Coatings

Extend the life of your footwear with these abrasion- and water-resistant epoxies. Stronger and more durable than most footwear materials, these epoxies are often used to coat and repair high-wear areas prone to rips, cracks, and water exposure, such as safety toes. They permanently bond to leather, plastic, and rubber. Each cartridge includes enough epoxy to coat the toes on one pair of shoes or boots. They fully harden in 24 hours and dry with a gloss finish, which can be rubbed away for a matte finish.
