COSMO TRANS is a one component high solids , polyurethane fluid, which cures with the humidity in the atmosphere. It produces an elastic , highly durable, highly hydrophobic membrane with excellent UV resistance. Being aliphatic , it does not yellow/discolour when exposed to sunlight.

It is based on pure elastomeric, hydrophobic , aliphatic polyurethane resin, which results in excellent mechanical , chemical , thermal , UV and natural element resistance properties.

Apply with roller in one or two coats.Minimum total consumption: 0.2-1.0 kg/m2.

Although COSMO TRANS looks coloured, especially when it is in large containers, it is stressed that the end result is, indeed , transparent.


Waterproofing and protection of:

  • Tiles,
  • Natural stone,
  • Wood,
  • Yerandas and balconies,
  • Terraces.

Also suitable for sealing concrete: Applied in thick, bubble-free, coats.

  • Not recommended for unsound substrates,
  • Non-porous substrates, such as ceramic tiles must be primed with COSMO TRANS PRIMER first.
  • No thinning is required but pure xylene may be used.
  • Excellent weather and UV resistance.
  • Excellent thermal resistance, the product never turns soft. Max service temperature 80 oC, max shock temperature 200 oC.
  • Resistance to cold: The film remains elastic even down to -40 oC.
  • Excellent mechanical properties.
  • Good chemical resistance.
  • Water vapor transmission.
  • Can also be applied in thick, bubble-free, coats.
