Rocathaan Primer UNI

1 of 5 products in this brand
Prokol Protective Coatings Rocathaan Primer UNI is a universal, 2-component, solvent-containing polyurethane primer with a very long application time and a short drying time for smooth and slightly porous surfaces. It is a particularly well-adhering primer on a very wide range of surfaces such as wood, many synthetic materials, aluminum and steel also on most non-oligomeric synthetics. It should not be applied to surfaces that are highly sensitive to solvents.

Mixing Instruction
  • 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.
Notes During Application
  • 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.
Surface and Circumstances

Moisture Content Surface:

  • Cement-bound : < 4% CM (parts by weights)
  • Plaster-bound : < 0.5% CM (parts by weights)

Steel Surfaces:

  • The surface must be free of substances which may have a negative influence on adhesion, such as oil and grease.
  • If these types of substances are present, they must first be removed with the appropriate agents and/or tools. Surface blasting, Sa 2,5, 75 -100 microns, DIN EN ISO 12 944. Then thoroughly remove all dust.
  • Formation of surface rust must be avoided at all times.
