Product Details
Shelf Life
12 months from date of production
Storage Conditions
The product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +10 °C and +25 °C. Always refer to packaging.
Density
| Part A | ~1.4 kg/l | (ISO 2811-1) |
| Part B | ~1.2 kg/l | (ISO 2811-1) |
| Parts A + B | ~1.4 kg/l | (ISO 1183-1) |
The density of the mixed material (A + B) is determined by calculation.
Shore A Hardness
| 85 ± 5 (after 28 days) | (ISO 868) |
Shore hardness assists with material identification and assessing the curing progress on site.
Tensile Strength
| ~3 N/mm2 | (ISO 527) |
Tear Strength
| ~8.5 N/mm² | (ISO 34 B) |

Application
Mixing Ratio
Part A : Part B = 100 : 11 (parts by weight)
Layer Thickness
minimum 3 mm / maximum 30 mm
Product Temperature
Condition product parts before application preferably at ~+15 °C to ~+25 °C.
Ambient Air Temperature
+5 °C minimum / +35 °C maximum
Relative Air Humidity
70 % maximum
Substrate Temperature
+5 °C minimum / +35 °C maximum
Substrate Moisture Content

| Sika® Icosit® KC 330 Primer | 1 hour | 3 days |
Consumption
~1.4 kg per litre of volume
SUBSTRATE QUALITY
Substrate must be sound, free from oil, grease, loose and friable particles.
Slightly damp substrates are acceptable. Standing water must be removed (e.g. by vacuum extraction or oil free compressed air) before pouring Sika® Icosit® KC 330 FK NEW.
SUBSTRATE PREPARATION
To improve adhesion, apply Sika® Icosit® KC 330 Primer as a primer on absorbent substrates (concrete).
MIXING
Sika® Icosit® KC 330 FK NEW is supplied in pre-weighed composite units consisting of parts A + B.
Part A must be stirred thoroughly before being mixed with part B.
The following mixing instructions must be carried out:
- Use an electric or pneumatic mixer with basket type stirrer (diameter 120–140 mm, speed ~600–800 rpm).
- Mixing time ~60 to 80 seconds.
- Ensure material is mixed from the container walls and the base by the stirrer during mixing.
During mixing until approximately 3 minutes afterwards, material remains liquid (pourable) and subsequently turns into a thixotropic, sag-resistant, trowel-applicable consistency.
CLEANING OF TOOLS
Mixing and application tools must be cleaned at regular intervals and immediately after use with Sika® Thinner C. Hardened material can only be removed mechanically.
