High temperature sealant

Final Advanced Materials can provide you high temperature sealants for application up to 980°C


High temperature sealant presentation

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 1529 - 1529H - 1529 UHT



Duraseal+ 1529 and 1529H

Low viscosity liquid sealants that will readily penetrate porous surfaces and cure at 180°C.


Duraseal+ 1529 FS 

A Low odor and VOC. formulation, medium viscosity sealant and coating for porous surfaces.


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 - 1532 - 1533


Duraseal 1531 - Continuous use to 340°C


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 1532 - Continuous use to 260°C


A clear thin putty with excellent spreading ability.
Excellent electrical insulation properties allow for a host of applications  in  cables  splicing,  electrical  isolation,  repair, potting, etc.
Ideal for use as high temperature adhesive, electronic,  
waterproofing, sealing, impregnating, coating or vibration dampening application.


Duraseal 1533 - 5 Minute  Casting Compound


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.
1533 can be used up to 260°C and offers flexibility, excellent mechanical properties and resistance to chemicals, solvents and  moisture.
