  • 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
