Viton Caulk Sealant & Adhesive

The Caulk Sealant:

This quality Caulk Sealant, based on Viton™ Fluoroelastomer and produced in conjunction with The Chemours Company, is perfect for splicing fluoroelastomer parts, sealing gaps and flanges + sealing lined pipes. It can also be used safely in corrosive and hazardous environments as it will not easily erode.

Fluorodyn™ protects steel, concrete and brick from corrosion. Non-porous and low permeability, the sealant resists virtually all chemicals, acids and gasses – including Nitric, Sulphuric, Hydrochloric Acids at temperatures up to 250ºC. It is also impervious to Aliphatic, Aromatic, Halogenated Hydrocarbons + Hot Oils, Water and Dry Heat. Ozone, U.V. Light, Salt Spray and Fungal Growth have little or no effect whatsoever.

The advanced compound system provides excellent corrosion resistance in the uncured state, as well as increased after curing to virtually all chemicals.

Fluorodyn™ has a shelf life of 2 years; it is compounded with 75% solids making it an easy to apply, single component caulk needing no mixing and eliminates expensive waste traditionally associated with other 2 part systems.


Colour – Black
Size available – 320ml cartridge

Can easily be applied by trowel or with a standard applicator gun.
