Polyurethane epoxy floor

Solvent-free anti-static system

This system not only possesses the dust-proof, clean, pressure-resistant and wear-resistant features of ordinary epoxy floors, but also can effectively prevent the accumulation of static electricity. By adding conductive polymers to the epoxy resin, the static electricity generated during production operations and that brought by foreign objects can be conducted and dissipated. The static electricity conduction performance is long-lasting.

1. Mix main paint and curing agent, stir evenly
2. Roll coat evenly, no missed areas


Notes

  • The application environment for topcoat: Temperature 5-30℃, relative humidity of air less than 80%. Excessive humidity may affect the strength and conductivity of the conductive layer, causing problems such as mottling and color floating of the topcoat.

  • Before the conductive layer is applied, it must be repaired and leveled with epoxy materials to completely seal the base surface.

  • The copper foil must be firmly adhered without lifting. After all the copper foils are connected, the conduction performance needs to be tested to check for any blind spots.

  • The conductive layer should be applied in one coat. When applying, ensure that the surface is smooth and flat without particles. After the application is completed, the resistance value should be less than 2×104 Ω.

  • Electrostatic dissipation type topcoat can be applied with topcoat putty, while conductive type topcoat cannot be applied with topcoat putty layer.

  • When troweling anti-static topcoat, avoid rapid lifting and dragging of the trowel. The formed bubble strings should be punctured with the trowel. After troweling, they must be treated with a defoaming roller.

  • For troweling construction, the amount of topcoat should be uniform. There should be no local accumulation or flow of materials, otherwise it will cause the conductive filler to float unevenly.

  • If the anti-static topcoat layer is reworked, the conductive layer must be reapplied; otherwise, the resistance value will not meet the requirements.

  • There are certain color differences among different batches of materials. When constructing in the same area, the same batch of materials should be used. When placing multiple orders for the same project, it must be noted that the color will be adjusted according to the sample

Construction conditions

  • Air temperature: 5℃ -30℃

  • Relative humidity < 80%

  • The moisture content of the substrate surface is less than 8%

  • The construction site should have good ventilation

  • Dew point temperature: The substrate and the substrate of the uncured coating must be at least 3℃ higher than the dew point temperature to reduce the risk of condensation or mottling of the ground coating

  • Oily floors must be thoroughly cleaned up; otherwise, it may affect the even application of the coating.
