Silicone sealent
Final Advanced Materials can provide you high temperature sealants for application up to 980°C. Those Cotronics® Duraseal® high temperature sealants are used for waterproofing, sealing, impregnating and coating in any high temperature application.
Duraseal High Temperature sealants are based on organic- inorganic formulations and can be used up to 980°C. Duraseal+ will increase dielectric properties, moisture proof and seal ceramics, thermocouples, cartridge heaters, end seals, etc. Commonly used for waterproofing Cotronics' ceramic fiber products, high temp. gaskets, sleeving and tapes.
Duraseal® 1529H - 1529 UHT
Duraseal® 1529 H
Low viscosity liquid sealants that will readily penetrate porous surfaces and cure at 180°C.
Duraseal® 1529 UHT
Now, for the first time, a silicone is combined with glass and a unique synergistic reaction forms a composite that will moisture-proof from room temperature to 980°C. Duraseal® 1529 UHT dries at 120°C and glazes at 590-760°C forming a surface for higher temperature applications.

Duraseal® 1531 - 1533
Duraseal® 1531
Seals pipes, flanges, stacks and high temp. equipment. No special surface pre-treatments are necessary. Adheres to most metals, glass, ceramics, plastics, etc. Fills in voids, forms flexible gaskets and repairs.
Duraseal® 1533
New, unique Duraseal® 1533 flows into the finest cracks and crevices to form stress free bonds, coatings and encapsulations. Easy to use 1 to 1 mix ratio. Difficult degassing procedures are not necessary. Just mix and pour. Casting will be tack free in 5 minutes and completely cured in 15-30 minutes. Duraseal® 1533 can be used up to 260°C and offers flexibility, excellent mechanical properties and resistance to chemicals, solvents and moisture.
