Sikadur®-61

Epoxy and PU resin with selected fillers

18 months from date of production

The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +30 °C. Always refer to packaging.

135 Pa·s at  23 °C

Non-sag up to 30 mm layer thickness

(1.5 ± 0.1) kg/m² per mm of thickness.

Consumption depends on the roughness and absorbency of the substrate.

Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

CONCRETE / MASONRY / MORTAR / STONE

Concrete and mortar must be at least 3–6 weeks old. Substrate surfaces must be sound, clean, dry or matt damp. Free from standing water, ice, dirt, oil, grease, coatings, laitance, efflorescence, old surface treatments, all loose particles and any other surface contaminants that could affect adhesion of the adhesive.

STEEL

Surfaces must be clean, dry, free from oil, grease, coatings, rust, scale, all loose particles and any other surface contaminants that could affect adhesion of the adhesive.

WOOD

Substrate surfaces must be sound, clean, dry and free from dirt, oil, grease, coatings, all loose particles and any other surface contaminants that could affect adhesion of the adhesive.

CONCRETE / MASONRY / MORTAR / STONE

Substrates must be prepared mechanically using suitable abrasive blast cleaning, needle gunning, light scabbling, bush hammering, grinding or other suitable equipment to achieve an open textured gripping surface profile.

STEEL

Surfaces must be prepared mechanically using suitable abrasive blast cleaning, grinding, rotating wire brush or other suitable equipment to achieve a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement. Avoid dew point conditions
before and during application.

WOOD

Surfaces must be prepared by planing, sanding or other suitable equipment.

ALL SUBSTRATES

All dust and loose material must be completely removed from all substrate surfaces before application of the product by vacuum / dust removal equipment.

IMPORTANT

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

1. Mix only the quantity which can be used within its pot life
2. Prior to mixing all parts, mix part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm).
3. Add part B (hardener) to part A and mix parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved.
4. To ensure thorough mixing pour materials into a clean container and mix again for approximately 1 minute. Do not over mix. Mix full units only. Mixing time for A+B = 4.0 minutes

IMPORTANT

Creep

Sikadur® resins are formulated to have low creep under permanent loading. However due to the creep behaviour of all polymer materials under load, when using adhesive for structural applications, the long term structural design load must account for creep.

• Generally the long term structural design load must be lower than 20−25 % of the failure load.
• A structural engineer must be consulted for design calculations for specific structural applications.

1. Apply mixed adhesive to the prepared surfaces with a spatula, trowel or notched trowel.
2. For optimum adhesion, apply adhesive to both surfaces that require bonding.
3. For heavy components positioned vertically or overhead, provide temporary support until the Product has fully hardened or cured. 
   Note: Hardening and curing will be dependent on ambient temperatures.

Clean all tools and application equipment immediately after use with Sika® Colma Cleaner. Hardened material can only be removed mechanically.
