Hychem TL6 — Multipurpose water potable AS4020 certified epoxy coating.

Prior to the application of TL6, the substrate must be thoroughly prepared.

• The concrete substrate must be firm, clean and dry with a minimum compressive strength of 25 MPa and a minimum surface tensile strength of 1.5 MPa.
• New concrete must be allowed to cure for a minimum of 28 days.
• Remove all surface laitance, contaminants, existing coatings, curing compounds and any weak or loose materials.
• Prepare the concrete surface by Grinding, Shot Blasting, Scarifying, Ultra High Pressure Water Jetting or Scabbling to provide the appropriate concrete surface profile (CSP) for optimum mechanical keying.
• The extent of surface preparation required is dependant upon but not limited to the thickness of the coating system to be applied. It is highly recommended that all surface preparation is carried out in accordance with industry standards and publications such as NACE 02203 item No. 22420 or ICRI Technical Guideline No. 03732.

The moisture content of the concrete must be below 6%.

Mix only enough quantity that can be applied within the work life which is temperature dependent.

Prior to the application of TL6 it is preferable to prime all new floor and wall surfaces with either E500P or E300. In some cases, re-coating existing coatings in sound condition may not require priming but only after thorough preparation. For tilt panel or FC sheet surfaces, new concrete with blowholes or heavily damaged existing concrete, a render coat of E500T may be necessary. Application of E500T can also reduce out gassing phenomena.

For application to steel and any other queries please contact

Hychem technical department for advice.

Roller Application

1. Add pigment pack to part A resin and mix thoroughly with a low speed mechanical stirrer until complete uniformity is achieved.

Add part B hardener and again mix until uniform. This should be achieved in approximately 3 minutes.

2. Apply the mixed product at a rate of approximately 5–7m²/litre/ coat (flooring) and 6–8m²/litre/coat for vertical applications over primed surfaces.
3. For anti-slip applications that require a more textured finish, add up to 10% white aluminium oxide aggregate by volume of the total mix. For course textured finishes, aggregate can be broadcast into the TL6. Please contact Hychem for a range of specific industry standard finishes.
4. To assist workability under certain conditions TL6 can be diluted using Xylene at a maximium rate of 10% by volume where necessary.

Please note this may affect pot life and cure times slightly.

Hychem TL6 is a specialised water potable coating suited to a large range of applications. TL6 can be roller applied to vertical and horizontal substrates including concrete and steel. TL6 is a high-build, multipurpose, solventless epoxy coating exhibiting a chemically resistant high gloss stippled finish.

Hychem TL6 is suited to water potable environments. It conforms to to AS/NZS 4020/2005 testing of products for use in contact with drinking water.

This kit will yield 6.5 litres with a 500 ml pigment pack.

Also available in a larger kit size. Please contact Hychem for further details.

1 x 6.5 litre kit of TL6 will cover approximately 40m² as a floor coating and 50m² as a vertical coating for walls.

These consumption rates are theoretical and can vary due to the porosity and the profile of the surface being coated. Overall film thickness will also be determined by the type of application or specification.

Please allow for wastage as well.

TL6 is an industrial epoxy finish which may discolour on exposure to UV light from the sun or an artificial source. The severity of discolouration is dependant on colour choice. Any such discolouration has no effect on the performance of the product.

12 months from date of manufacture, stored under shelter at 25°C in the original un-opened container.

To minimise an unsatisfactory cure the following indicative application conditions should be observed with respect to temperature and humidity levels.

• 21°C and less than 85% humidity
• 10°C and less than 75% humidity
