Features & Benefits

  • The Product is used as a structural adhesive for bonding the following:
    • Fresh concrete to hardened concrete
    • Concrete elements
    • Hard natural stone
    • Ceramics and fibre cement
    • Mortar, bricks, masonry and render
    • Iron and steel
    • Wood
    • Polyester, epoxy, polyurethane (PU) grouts (e.g. Sika® Icosit® KC Range)
    • Polyester / fibreglass and epoxy resin material
  • The Product is used as an adhesive for fixing and anchoring the following:
    • Small anchors
    • Fasteners
    • Railway fasteners
  • The Product is used as a primer for the Sika Icosit KC System:
    • On prepared dry and matt damp concrete surfaces
    • On prepared metal surfaces
  • Product Declaration: 
    • EN 1504-4: Structural bonding
    • EN 1504-6: Anchoring



Preparation & Application


  • It is essential that both components are fully used, ensuring no excess material remains within the container prior to mixing - failure to do so could adversely affect the chemical reaction
  • Beware of condensation

Substrate Quality:

Concrete, Masonry, Mortar or Stone:

  • Concrete and mortar must be at least 28 days old
  • Substrates must be sound, clean, dry or matt damp with no standing water
  • Substrates must also be free from contamination such as ice, dirt, oil, grease, coatings, laitance, efflorescence, surface treatments and loose friable material

Steel:

  • Surfaces must be sound, clean, dry and free of all contaminants such as dirt, oil, grease, coatings and loose friable material
  • Steel substrate temperature during application must be at least 3 °C above dew point

Wood:

  • Surfaces must be sound, clean, dry and free of all contaminants such as dirt, oil, grease, coatings and loose friable material

Ceramics or Glass:

  • Surfaces must be sound, clean, dry and free of all contaminants such as dirt, oil, grease, coatings and loose friable material

Substrate Preparation:

Important - Reduced adhesion performance:

  • Surface contamination such as dust and loose material, including that caused during substrate preparation can reduce the Product's performance

Concrete, Masonry, Mortar or Stone:

  • Substrates must be prepared mechanically using suitable equipment to achieve an open-textured, gripping surface profile
  • Suitable techniques for substrate preparation include the following:
    • Abrasive blast cleaning
    • Needle gunning
    • Light scabbling
    • Bush hammering
    • Grinding

Steel:

  • Suitable techniques for substrate preparation include the following:
    • Abrasive blast cleaning
    • Rotating wire brush
    • Grinding
  • The substrate has a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement

Wood:

  • Prepare the substrate by planing, sanding or using other suitable equipment

Ceramics or Glass:

  • Prepare the substrate by sanding or using other suitable equipment

Mixing:

Maintaining workability and handling time:

  • When using multiple units during application, do not mix the following unit until the previous one has been used

Pre-batched units:

  • Mix full units only
  • Prior to mixing all parts, mix Part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (maximum 300 rpm)
  • Add Part A to Part B (hardener) ensuring all material has been removed and added to Part B
  • Mix Parts A+B continuously for at least 3 minutes until a uniformly coloured, smooth consistency mix has been achieved
  • Do not overmix
  • To ensure thorough mixing pour materials into a clean container and mix again for approximately 1 minute
  • Mixing time for Parts A+B = 4 minutes

Application:

Provide temporary support for heavy components positioned vertically or overhead.

Bonding Applications:

  • On damp prepared concrete substrates, always apply by brush and work the Product well into the substrate
  • Apply the mixed Product to the prepared substrate by brush, roller, spray or trowel ensuring uniform and complete coverage
  • For optimum adhesion, apply the adhesive to both substrates that require bonding
  • For bonding wet fresh concrete to hardened prepared concrete, place the concrete whilst the resin layer is still tacky
  • Note: If the product becomes glossy and loses tackiness, apply another coat and proceed to place concrete

Anchoring Applications:

  • For small anchors or fasteners, clean the hole thoroughly with a special round steel brush and with compressed air (minimum pressure 6 bar), starting from the bottom
  • Once the hole is completely clean and free of any loose particles or dust, pour the Product in the hole, avoiding entrapping air
  • Insert the anchor or fastener with a rotary motion within the adhesive open time
  • Note: Some of the adhesive must flow out of the hole
  • During the resin hardening time the anchor must not be moved or loaded

Cleaning of tools:

  • Clean all tools and application equipment with Sika Thinner C immediately after use
  • Hardened / cured material can only be mechanically removed



Limitations


  • The Product will not adhere to substrates with a siliconised surface
  • Sikadur resins are formulated to have low creep under permanent loading
  • However, due to the creep behavior of all polymer materials under load, the long term structural design load must account for creep
  • Generally the long term structural design load must be lower than 20% to 25% of the failure load
  • A structural engineer must be consulted for load calculations for the specific application

Important:

  • Ensure product is protected from rain / moisture for at least 24 hours after application
  • Do not apply material if either substrate, ambient or product temperature is below 10°C
  • Temperatures below this will have an adverse affect on curing and product performance
