COLOURSEAL -  a silicone faced pre-compressed expanding foam tape joint sealant 

Replacement for traditional wet sealants

 

Colourseal - joint sealant

Colourseal - Mayfair

 

 COLOURSEAL Applications
  • Joints in concrete and brickwork

  • Joints subject to thermal or differential movement

  • Weather tight seal

  • Pre-cast concrete panels

  • Vertical joints ( for horizontal joints, refer to Colourseal 'H' data sheet)

  • Joints subject to high movement

  • COLOURSEAL has a movement capability of up to +/- 50% of the mean joint size.
 

 
 
Product Information   Advantages
  • COLOURSEAL combines a factory-applied low-modulus silicone, acrylic impregnated expanding foam sealant and closed-cell (EVA) foam into a unified binary sealant system 

    •  
  • The expanding foam laminations are Flowseal - an open-cell polyurethane foam impregnated with a water-based, stabilised, polymer-modified acrylic

    •  
  • The silicone external and colour weather facing is factory-applied to the foam while it is partially pre-compressed. The silicone is then cured and when finally compressed, a bellows is formed in the coating. The bellows virtually eliminates tensile stresses at the silicone/substrate interface 

    •  
  • Puncturing of the silicone facing does not affect the seal integrity 

    •  
  • COLOURSEAL is supplied shrink-wrapped and pre-compressed in 2 metre lengths 

    •  
  • Choice of 4 standard colours (black, grey, white, & brick), with further choice of 7 non-standard colours 

    •  
  • Suitable for joint sizes 20mm - 150mm (others available) 

    •  
  • High movement capabilities: +/- 50% of nominal joint width 
  
  • Joint movement capability of up to +/-50% of nominal joint width

  • Features the UV resistance, durability and the impermeability of silicone

  • Virtually eliminates tensile stresses at bond line and adverse effects of movement occurring before field applied silicone cures

  • Reduced installation, labour and material charges

  • Less reliant on meticulous substrate preparation

  • Seal integrity maintained if silicone is punctured

  • Easy to install
