Rocathaan Topcoat 35

• Very high CO2 resistance against atmospheric contamination and various chemicals
• High mechanical resistance
• Smooth and tight topcoat that gives dirt little chance of adhering and makes the surface easy to clean.
• Thanks to the very low water absorption properties, it is excellent to use as a seal against penetrating moisture
• UV-resistant, therefore, gloss and color are maintained
• Non-thermoplastic, therefore, the surface remains hard even at higher temperatures

Brush, roller

0.15 - 0.30 kg/m²/layer; The application of two layers is highly preferred.

• Object: +5 and +35 ºC
• Product: +10 and +35 ºC

• Recoat Time*: 18 - 36 hours
• Chemical resistant*: After 7 x 24 hours
• Mechanical resistant*: After 3 x 24 hours
• Water resistant*: After 7 x 24 hours
• Induction time: 5 minutes
• Dilution:
  • Rocathaan thinner.
  • A maximum of 5% only to be added once base(A) and hardener(B) have been mixed.
  • Adding thinner can affect the properties
• Cleaning agent: Roca Cleaner R5518 (equipment)
• * At 20 ºC and 65% RH surface.

• 2-component products must always be mechanically mixed, preferably with a continuously adjustable mixing machine/drill (300 - 400 RPM) or another suitable mixer/whisk.
• As a guideline, the diameter of the mixer/whisk must be at least 1/3 of the diameter of the container in which the product is mixed in.
• First mix component A until it is a homogenous mixture.
• Add component B (completely drained or scraped) to component A and mix at least 2-3 minutes until it is a homogenous mixture.
• To exclude unmixed materials (bottom/sides) are processed, transfer the mixture to a clean mixing bucket/tub and mix again.
• When using additives such as quartz sand or the like, only add when the mixture is a homogenous mixture.
• After adding, please mix thoroughly again.
• When mixing parts, both components must be mixed separately and carefully and weighed accurately.

• 2-component products may only be applied when the relative humidity is less than 85%.
• The minimum surface temperature is +5°C and the temperature of the surface to be treated and the uncured product must be 3°C above the dew point.
• See the dew point table. The curing process occurs more quickly at higher temperatures and slower at lower temperatures.
• The potlife is partly dependent on the product temperature.
• Ensure good ventilation during curing. Insufficient ventilation, notably on the floors of swimming pools and other basins, bottoms of trailers, may result in slow and irregular curing of the applied primer layer.
• Entrapped solvent can lead to blistering and debonding of a subsequent layer.
