PRODUCT GUIDE – ADHESIVES & SEALANTS

 

The range of Fortafix adhesives and sealants mainly comprise of two distinct types which largely define their performance benefits, limitation, and temperature thresholds. There is a fundamental temperature threshold (up to approx. 300-350°C) which governs the chemical stability of adhesives and potting compounds.

 

Silicone Based (organic i.e. carbon based)

For materials which operate successfully at a temperature below 350°C Fortafix have a wide range of ‘organic’ polymers available, which have many applications. Unfortunately, these materials will not withstand exposure above maximum of 350°C and undergo significant degradation above this point and not resistant to direct flame.

Silicones main properties are:

  • Flexible – Elastomeric
  • 100% Solid
  • Fracture Tough
  • Resistant to Water / Steam
  • Adhere to many substrates (Organic and Inorganic)
  • Temperature Limit of 350°C Max.
  • Not resistant to flame.

The Fortafix Silicone range consists of:

Flexseal TR – Temperature resist to 300C for short periods – colour Black.
Flexseal HT 300 – Continuous operating temperature of 300C – colour Black and ‘Food Safe’ White
Flexseal 350 – Highest operating temperature of any Silicone at 350C – colour Red.
Flexseal FR – Fire resistant silicone for use in conjunction with fire resistant construction. – colour Grey
Flexseal Bondflow 300 – Pourable Silicone for potting and coating to 300C – colour Black or White.
Flexseal Bondflow 350 – Pourable Silicone for potting and coating to 350C – colour Red.

Silicate Based (inorganic i.e. ceramic/glass based)

For materials which operate successfully at a temperature above 350°C – there are a range of reactive ‘inorganic’. Unfortunately, these materials are prone to some re-solution of water soluble components under immersion or exposure to steam.

Silicate main properties are:

  • Rigid
  • Resistant to chemicals / solvents
  • Fire Resistant to Class A1
  • Adheres to inorganic materials
  • Temperature resistant up to 1600 (dependent on type)
  • Not resistant to moisture

The Fortafix Silicate range consists of:

Flamebond Range – Various viscosity non-combustible adhesive/sealants for fire protection – compliant with BS 476: Part 4 / EN13501-1 Class A1
Fiborclad Range – Various viscosity adhesive/sealants for joining/sealing industrial insulation – up to 1000c
Autostic FC & FS – Highly Versatile adhesives/sealants for engineering applications – up to 1000C.
Autostic Adhesium Roll – A unique semi-permanent machine mounting compound.
Autostic Rocksett – High Temperature Thread lock to 750C.
Light/Med/Heavy Grade – Adhesives developed for electrical and temperature resistance.
Ceramix TC Caulking – Exceptional technical performing Adhesive/Sealant suited to many application to temperatures of 1250C.
Ceramix U529NH – Develop as a high temperature strain gauge adhesive cement to match specific thermal expansion.
