Epoxy resin

12 months from date of production

The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +10 °C and +30 °C. Always refer to packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

Hardens without shrinkage

Non-sag, suitable for overhead application

Beware of condensation. Substrate temperature during application must be at least +3 °C above dew point.

Substrates must be dry or matt damp (no standing water).

Minimum cartridge temperature +10 °C

Minimum cartridge temperature +10 °C

250ml cartridges require a standard, keyed action applicator gun. 

400ml cartridges require a 1:1 ratio, side by side applicator gun, with a thrust ratio of 26:1 (available from Sika). 

CONCRETE, MASONRY, MORTAR, STONE

Concrete and mortar must be at least 28 days old.

Substrates must be sound, clean, dry or matt damp but free of standing water. Substrates must be free of contaminants 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 contaminants such as dirt, oil, grease, coatings and loose friable material.

WOOD

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

IMPORTANT

Reduced adhesion due to surface contamination

Surface contaminants such as dust and loose material, including the contaminants generated during substrate preparation, can reduce the Product's performance.

Before applying the Product, clean thoroughly all substrate surfaces using vacuum or dust removal equipment.

CONCRETE, MASONRY, MORTAR OR STONE

Suitable techniques for substrate preparation include the following:

• Abrasive blast cleaning.

• Needle gunning.

• Light scabbling.

• Bush hammering.

• Grinding.

Prepare the substrate mechanically using a suitable technique.

The substrate has an open-textured, gripping surface profile.

STEEL

Suitable techniques for substrate preparation include the following:

• Abrasive blast cleaning.

• Rotating wire brush.

• Grinding.

Prepare the substrate mechanically using a suitable technique.

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.

PREPARING THE CARTRIDGE

1. Unscrew and remove the cap from the cartridge.

2. Remove the plug from the end of the cartridge.

   Note: 250 ml cartridge only.
3. Screw the static mixer nozzle to the open cartridge.
4. Place the cartridge into the application gun.

IMPORTANT

Damage due to unsupported heavy components applied vertically or overhead

Full adhesion is not achieved before the Product has fully hardened. Hardening depends on ambient temperatures. Unsupported heavy components might fall down when not supported.

Provide temporary support for heavy components until the Product has fully hardened.

Hardened material in the static mixer nozzle

Note: When work is interrupted, the static mixer nozzle can remain on the cartridge after the pressure of the sealant dispenser has been released.

Attach a new nozzle if the resin has hardened in the nozzle when work is resumed.

BONDING

Preconditions

Prior to application confirm dew point conditions before and during application.

1. Pump the Product until both parts are extruded as one consistent colour.
2. Release the gun pressure and clean the static mixer opening with a cloth.
3. Discard inconsistently coloured Product parts.
4. Apply the Product to the prepared substrate using specific application gun.
5. For optimum adhesion apply the adhesive to both surfaces that require bonding.
6. For heavy components positioned vertically or overhead, provide temporary support until the Product has fully hardened.
7. Immediately clean tools with Sika® Thinner C.
8. Wash hands and skin thoroughly with warm soap water.

REPAIR

Preconditions

Prior to application confirm dew point conditions before and during application.

1. Pump the Product until both parts are extruded as one consistent colour.
2. Release the gun pressure and clean the static mixer opening with a cloth.
3. Discard inconsistently coloured Product parts.
4. Apply the Product to the prepared substrate using specific application gun.
5. Finish the surface of the repair with a spatula or trowel if required.
6. Immediately clean tools with Sika® Thinner C.
7. Wash hands and skin thoroughly with warm soap water.

JOINT FILLING AND CRACK SEALING

Preconditions

Prior to application confirm dew point conditions before and during application.

1. Pump the Product until both parts are extruded as one consistent colour.
2. Release the gun pressure and clean the static mixer opening with a cloth.
3. Discard inconsistently coloured Product parts.
4. Apply the Product to the prepared substrate using specific application gun.
5. For a smooth finish tool the surface of the joint or crack using a spatula.
6. Immediately clean tools with Sika® Thinner C.
7. Wash hands and skin thoroughly with warm soap water.

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