Product Details

Chemical base

Epoxy resin

 

Shelf life

12 months from date of production

 

Storage conditions

The Product must be stored properly in original unopened, sealed and undamaged packaging in dry conditions at temperatures between +5 °C and +40 °C. Protect from direct sunlight.

 

Density

~1.3 kg/L (Part A+B mixed, +30 °C)

 

System structure

Substrate primer

Impregnating / laminating resin

Sikadur®-330 IN

Structural strengthening fabric

SikaWrap® type to suit requirements

Modulus of Elasticity in Flexure

~2800 N/mm2 (7 days at +30 °C)

(ISO 178)

 

Tensile strength

~30 N/mm2 (7 days at +30 °C)

(EN ISO 527-2)

 

Tensile adhesion strength

~4 N/mm2 (concrete failure, 7 day, +30 °C)

(EN 1542)

 

Service temperature

Maximum

+45 °C

Minimum

0 °C

 

Heat deflection temperature

+52 °C (7 days, +30 °C)

(ASTM D648)

Resistant to continuous exposure +45 °C.

Application

Mixing ratio

Part A : Part B = 4 : 1 (by weight)

 

Ambient air temperature

+10 °C min. / +40 °C max.

 

Dew point

Beware of condensation.
The substrate and uncured applied resin must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the resin surface.

 

Substrate temperature

+10 °C min. / +40 °C max.

 

Substrate moisture content

≤ 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).

 

Pot life

~35 minutes (100 g mass at +30 °C)

(FIP 5.1)

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).

 

Open time

~60 minutes (100 g mass at +30 °C)

(FIP 5.2)

 

Waiting time / Overcoating

6 hours minimum at +30 °C

Cured resin older than 7 days has to be degreased with Sika® Colma Cleaner and gently grinded with sandpaper before coating.

Times are approximate and will be affected by changing ambient conditions.

 

Applied product ready for use

7 days (full cure at +30 °C)

Times are approximate and will be affected by changing ambient conditions.

Consumption

Guide: 0.4–1.5 kg/m2

Consumption will depend on the roughness of the substrate and the type of SikaWrap® fabric to be impregnated. See respective SikaWrap® fabric Product Data Sheet and also refer to:

  • Method Statement: SikaWrap® manual dry application – Ref 850 41 02
  • Method Statement: SikaWrap® manual wet application – Ref 850 41 03

SUBSTRATE QUALITY

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

Reference must be made to the Sika® Method Statements:

  • Method Statement: SikaWrap® manual dry application – Ref 850 41 02
  • Method Statement: SikaWrap® manual wet application – Ref 850 41 03
 

SUBSTRATE PREPARATION

Reference must be made to the Sika® Method Statements:

  • Method Statement: SikaWrap® manual dry application – Ref 850 41 02
  • Method Statement: SikaWrap® manual wet application – Ref 850 41 03

 

MIXING

IMPORTANT

Mix full units only

IMPORTANT

Over mixing must be avoided to minimise air entrainment.

  

  1. Add Part B (hardener) to Part A (resin).
  2. Mix Parts A+B continuously for ~3 minutes until a uniformly coloured mix is achieved.
  3. To ensure thorough mixing, pour materials into a clean container and mix again for approximately 1 minute.

 

APPLICATION

Reference must be made to the Sika® Method Statements:

  • Method Statement: SikaWrap® manual dry application – Ref 850 41 02
  • Method Statement: SikaWrap® manual wet application – Ref 850 41 03

 

CLEANING OF TOOLS

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