Sikafloor-3240 | MCT CHEMICALS | SIKA PAKISTAN

DESCRIPTION
Sikafloor®-3240 is a two-component, solvent-free, colored self-smoothing polyurethane (PUR) resin with tough-elastic properties. It utilizes Sika’s innovative i-Cure technology to enhance surface appearance and minimize sensitivity to ambient humidity during application. This product is also suitable for use in hot and tropical climates.

USES
Sikafloor®-3240 is intended for use by experienced professionals. It is ideal for:

• A smooth, crack-bridging surface for industrial floors in production and storage facilities, workshops, etc.
• A broadcast surface for crack-bridging applications in wet areas, such as food and beverage industries, car park decks, and loading ramps.
• Suitable for use on asphalt surfaces and in indoor environments like shopping centers, exhibition halls, and storage areas.

CHARACTERISTICS / ADVANTAGES

• Flexible and tough-elastic.
• Crack-bridging properties.
• Can be applied on asphalt substrates (mastic asphalt).
• Good chemical and mechanical resistance.
• Solvent-free with low VOC emissions.
• Slip-resistant surface options available.
• Easy to apply and maintain.
• Economical and moisture-resistant.

• Consumption: Refer to the System Data Sheets for detailed guidance.
• Ambient Temperature: +10°C min. / +30°C max.
• Relative Humidity: ~75-80%
• Dew Point: Ensure substrate and uncured floor are at least 3°C above dew point to avoid condensation or surface blooming.
• Substrate Temperature: +10°C min. / +30°C max.
• Substrate Moisture Content: <4% pbw moisture (measured by Sika®-Tramex meter or similar methods).

Pot Life

• At +10°C: ~40 minutes
