Epoxy resin

24 months from date of production

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

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

Mixed resin 1.30 ± 0.1 kg/L (at +23 °C)

Shear rate: 50/s

• Substrate primer: Sikadur®-330

• Impregnating and laminating resin: Sikadur®-330

• Structural strengthening fabric: SikaWrap® type to suit requirements

Resistant to continuous exposure +45 °C.

Part A : Part B = 4 : 1 by weight

The substrate temperature must be at least +3 °C above dew point to reduce the risk of condensation decreasing adhesion.

≤ 4 % parts by weight

The following test methods can be used: Sika®-Tramex meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).

The pot life begins when Parts A+B are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot life. To obtain longer workability at high temperatures, the mixed adhesive may be divided into smaller quantities. Another method is to chill Parts A+B before mixing (not below +5 °C).

Guide: 0.7–1.5 kg/m² 

Also refer to: 850 41 02 Method Statement SikaWrap® manual dry application

Substrates must be structurally sound and of sufficient tensile strength to provide a minimum tensile strength of 1.0 N/mm² or as required in the design specification.

PRE-BATCHED UNIT

1. Mix part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm).
2. IMPORTANT Mix full units only. Add part B (hardener) to part A.
3. Mix parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved.
4. IMPORTANT Avoid entraining air into the mix by over-mixing. To ensure thorough mixing, transfer the mixture into a clean container and mix again for 1 additional minute.

BULK CONTAINER

1. IMPORTANT Mix only the quantity which can be used within its pot life. Mix part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm).
2. Add both parts in the correct proportion into a suitable clean, dry container.
3. Mix parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved.
4. IMPORTANT Avoid entraining air into the mix by over-mixing. To ensure thorough mixing, pour materials into a clean container and mix again for 1 minute.

Reference must be made to the following Sika® Method Statements:

IMPORTANT

Application by trained personnel

The application of this Product must only be carried out by an applicator that is trained or approved by Sika. The applicator must also be experienced in this type of application.

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

Preconditions

For application in cold or hot conditions, pre-condition the material for 24 hours in temperature-controlled storage facilities.

Dry before application of the next layer or coating.

1. At low temperatures or high relative humidity, a tacky residue (blush) may form on the surface of the cured product. To apply an additional layer of fabric or a coating remove the residue with warm soapy water to ensure adequate bond.
2. Protect from rain for at least 24 hours after application.

For further information on number of layers or creep, consult a structural engineer for calculations.

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