COLLE CONDUCTRICE is a solvent free acrylic conductive adhesive filled with carbon chips, which is designed to give a high bond strength with strong initial tack and a long working time, with good plasticiser resistance. It is protected against biodegradation and is suitable for use over normal underfloor heating installations.
FOR SECURING conductive/antistatic PVC and rubber floor coverings.
For bonding onto subfloors of concrete, sand/cement screed, anhydrite screeds, smoothing underlayments, flooring grade plywood and timber.
It prevents when used with our conductive primer the build-up of voltage potential and electrostatic loadings, e.g. in operating rooms in hospitals, computer rooms, laboratories, telecommunications centres, workrooms and storage areas.
For interior use only.

PREPARATION
Preparation should be in accordance with building standards. Subfloors must be sound, even, smooth, permanently dry and free from old adhesive residues, dust, grease or other contaminants. Remove dirt, polish, oil and similar contaminating substances.
When further preparation of the subfloor is required, select suitable Bostik primers and Bostik smoothing and levelling compounds. Very absorbent surfaces must be primed to prevent unacceptably rapid drying of adhesive. Anhydrite screeds as well as particleboards and plywood should be primed with solvent-based primer IMPREGLUE, several subsequent coats may be necessary (100-120 g/m²/coat).
All surfaces must incorporate adequate damp proofing, if not, they should be primed with EPONAL 336 Moisture Vapour Barrier coating.
Always allow primers and underlayment to dry thoroughly before applying the adhesive.
Conductive system
Before installing conductive floor coverings, a conductive system must be fixed to the subfloor and this must be later connected to earth by a qualified electrician in accordance with trade regulations.
When used with copper-strip:
Adhere the copper foil with Colle conductrice. It generally consists of 10-20 mm wide copper strips laid in a grid pattern and connected to earth every 40-60 m². COLLE CONDUCTRICE must completely cover the copper foil.
When used with Conductive Primer :
Apply our Primaire Conducteur 2 to 4 hours prior to applying our conductive adhesive. It is necessary to place a 1.5- or 2-metre length of copper strip onto the prepared substrate for every 40 m² of floor area. (Consult PRIMAIRE CONDUCTEUR technical data sheet).
APPLICATION
In all cases, refer to the manufacturer's installation instructions regarding conductive floor covering.
Stir the adhesive until smooth consistency and grey colour is obtained. Apply the adhesive evenly over the subfloor using a suitable notched trowel.
The choice of notched trowel depends on substrate absorbency and its roughness.
Notched trowel n° 2 : 250 g/m² - for all floor coverings with smooth backing (PVC tiles or in sheet).
Notched trowel n° 3 : 300 g/m² - for rough/structured backings (carpeting with synthetic backing).
Allow an appropriate open time (approx. 10 minutes), depending on temperature and humidity conditions; substrate absorbency and type of floor covering.
Use a rubbing block and/or roller to expel trapped air and to ensure good transfer of the adhesive. After 30-40 minutes, repeat.
Joins and levelling should be carried out in accordance with the manufacturer’s installation instructions. Do not weld vinyl floor coverings until the adhesive has had sufficient time to develop a good bond, normally 24-48 hours after installation.
For works requiring guaranteed conductivity, it is necessary after the installation to check electrical resistivity of the entire system (substrate and floor covering) according to the norms and standards of the country.
Cleaning
Tools should be cleaned with water while the adhesive is still wet.
