Technical Information

Electrostatic Behaviour

Typical Average Resistance to Ground:

Rg ≤ 104 Ω*

In Combination with a Sika® Electrostatic Conductive Floor Covering:

Rg ≥ 107 Ω ≤ 109 Ω*

* Readings may vary, depending on ambient conditions (i.e. temperature, humidity, etc.) and measurement equipment.

Dew Point

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

Substrate Temperature

+10 °C minimum / +30 °C maximum

Substrate Moisture Content

≤ 4 % percentage 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).

Application steps

MIXING

Prior to mixing all parts, mix separately Part A (resin) using an electric single paddle mixer (300–400 rpm) or other similar equipment. Mix liquid and all the coloured pigment until a uniform colour / mix has been achieved. Add Part B (hardener) to Part A and mix Part A + B continuously for at least 2 minutes until a uniformly coloured mix has been achieved. To ensure thorough mixing, pour materials into a clean container and mix again for at least 1 minute to achieve a smooth, consistent, homogeneous mix. Excessive mixing must be avoided to minimise air entrainment. During the final mixing stage, scrape down the sides and bottom of the mixing container with a straight edge trowel or spatula at least once to ensure complete mixing. Mix full units only. Mixing time for A+B = >3 minutes.

 

APPLICATION

Apply Sikafloor®-221 W Conductive onto the prepared, primed substrate and apply by short pile nylon roller (12 mm), then back roller in two directions at right angles to each other. Ensure a continuous, pore-free coat covers the substrate.

Confirm waiting / overcoating time has been achieved before applying subsequent products.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
