Hyperdesmo H®


Novel, all weather rapid curing, single component polyurethane liquid membrane for waterproofing and
protection based on Humidity-Activated-Accelerator, Technology


HYPERDESMO®-H is a unique single
component polyurethane liquid membrane, based on the successful combination of Hyperdesmo and Accelerator 3000 which throughout the years has provided applicators with a solution for a fast curing, bubble free thick layer membrane. Our commitment to R&D and investment and our efforts to continuously upgrade our Chemical processing plant has allowed us to formulate a 
Hyperdesmo® with the Accelerator 3000 incorporated in a blocked fashion, that upon contact with humidity is released and selfaccelerates the curing of the material in a similar
manner as the Accelerator 3000.


Due to its unique formulation, it cures rapidly to form a completely defect free membrane with excellent mechanical and elastomeric properties. This product is ideal for use during the winter months or in climates with relatively low humidity. Furthermore, the fact that the minimum consumption can now be achieved in only one coat, reduces labor cost and eliminates previous drawbacks of the Hyperdesmo® + Accelerator system such as short working time or problems associated with using Hyperdesmo on its own in multilayer coats adhesion failure.


Apply with brush, roller or airless spraying
Minimum consumption: 1.5 - 3.0 kg/m²

Features & Benefits

  • Fast curing! Skin formation time of 2 hours

  • bubble and defect free membrane

  • No thinning is required but SOLVENT-01 may be

  • Excellent weather and UV resistance. The white
    colour reflects much of the solar energy and so
    reduces the internal temperature of buildings

  • Excellent thermal resistance, the product never turns soft. Recommended service temperature 80°C, max shock temperature 200°

  • Resistance in the cold: The film remains elastic
    even down to -40°C.

  • Excellent mechanical properties, high tensile
    and tear strength, high abrasion resistance.

  • Good chemical resistance

  • Moisture vapor transmission: The film breathes so there is no accumulation of humidity under the coat.

  • Special primers available for almost every



Apply the material with roller or brush in one or two, coats. Do not exceed 48 hours between coats. If more time passes (for example more than 4 days) or if you are unsure of the interlayer adhesion, please contact our technical
