Water-based polyurethane

The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5°C and +30°C. Always refer to packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

Note: Measurement results can be affected by ESD clothing, ambient conditions, measurement equipment, cleanliness of the floor and the test personnel.

Resistant to many chemicals. Contact Sika technical service for specific information.

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

Before overcoating Sikafloor®-305 W ESD allow:

Based on RH max. 70 % and good ventilation. Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

Cementitious substrates must be structurally sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum tensile strength of 1.5 N/mm².

Substrates must be clean, dry and free of contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.

IMPORTANT

Application on epoxy substrates

When applying the Product on an epoxy substrate, the floor must be sanded to secure proper adhesion.

1. Sand the substrate with a 3M Brown Stripper Pad in combination with low-speed automatic scrubbers or rotary floor machines (175 to 600 rpm).

IMPORTANT

Insufficient coating due to uneven or dirty substrates

Uneven or dirty substrates cannot be covered by thin seal coats.

1. Clean the substrate and adjacent areas thoroughly prior to application.

1. Vacuum the substrate to remove all dirt and contamination prior to application.

1. Prior to mixing all parts, mix Part A (resin) using an electric single paddle mixer. Mix liquid and all the coloured pigment until a uniform colour and mix has been achieved.
2. Add Part B (hardener) to Part A.
3. Mix Part A + B continuously for ~3 minutes while adding 10 % water until a uniformly coloured mix is achieved. Note Avoid excessive mixing to minimise air entrainment.
4. Leave the Product to stand for 10 minutes before application.

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

IMPORTANT

Protect from moisture

After application, protect the Product from damp, condensation and direct water contact for at least 24 hours.

IMPORTANT

Damaged finish due to heating with fossil fuel heaters

Fossil fuel heaters powered by gas, oil or paraffin produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish.

1. For temporary heating, use only electrically powered warm air blower systems. Do not use gas, oil, paraffin or other fossil fuel heaters.

IMPORTANT

Reduced conductivity due to mechanical or chemical damage

Damage to the floor surface can lead to reduced conductivity.

1. Monitor the conductivity of floor regularly
2. In the event of floor wear or damage refresh the Product. This must be co-ordinated with the authorised ESD representative.

Exact colour matching

Note: For exact colour matching, ensure the Product in each area is applied from the same control batch number.

Polishes to reduce aesthetic damage

Note: Tires can cause dark marks to the Product from plasticiser migration. To generally improve the ability to clean the floor the Product can be protected with a polish.

1. Overcoat the floor with a static dissipative floor polish such as Jontec ESD or Jontect Destat

Preconditions

The substrate moisture content, relative humidity and dew point are appropriate for application. Note The floor must be divided into sections (at expansion joints or doorways when possible) that can be completed without stopping.

1. Apply the mixed Product in the corners, around columns and other installations by short pile roller. Note Maintain a "wet edge" during application to achieve a seamless finish.
2. Distribute the mixed Product at the correct consumption rate crosswise with a short pile nylon roller. Note Maintain a "wet edge" during application to achieve a seamless finish.

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