PU Based Waterproofing

HYPERDESMO®HYPERDESMO® is a one component polyurethane fluid which cures with the humidity in the atmosphere. It produces a highly elastic membrane with strong adhesion to many types of surfaces. It contains a small percentage of xylol, and may be thinned with SOLVENT-01 if necessary.

It is based on pure elastomeric hydrophobic polyurethane resin plus special inorganic fillers, which result in excellent mechanical, chemical, thermal, UV and natural element resistance properties.

Apply with brush, roller or airless spraying in two coats, at least, with minimum total consumption of 1.5-1.8 kg/m2.

Waterproofing and protection of:

  • Tiles,
  • gypsum and cement boards,
  • polyurethane insulation foams,
  • bathrooms,
  • verandas and balconies,
  • roofs,
  • light roofing made of metal or fibrous cement,

HYPERSEAL®-25LMHYPERSEAL®-25LM is a novel low modulus expansion joint sealant, especially formulated to contain both PU and silylated – PU technology, thus giving rise to a sealant which includes the best of both technologies. HYPERSEAL®-25LM cures by reaction with atmospheric humidity to produce a joint sealant with a 50% joint movement accommodation factor, which has excellent adhesion on substrates traditionally problematic for PU sealants, e.g. glass, aluminum, steel, polycarbonate, etc.. Additionally, the sealant has been modified in order to have extrusion profile identical to hybrid PU or MS technology. The extrusion rate and tooling of the sealant remain the same throughout a very wide range of temperature and humidity conditions. The sealant is easy to apply even in very low temperatures and the storage stability is unlike any polyurethane sealant in the market.

HYPERSEAL®-25LM complies with:

  • ISO-11600,
  • Type F,
  • class: 25LM,
  • DIN-18540-F,
  • ASTM C920,
  • U.S. Federal Specification TT-S-00230C,
  • Type II Class A.

Sealing joints in:

  • Insitu concrete,
  • expansion concrete joints,
  • precast panels,
  • brick and block work,
  • water tanks and swimming pools,
  • metal frames,
  • aluminum windows and panels,
  • irrigation channels,
  • glass & mirror applications,
  • granite & marble

MICROSEALER-PUMICROSEALER-PU is a one component, 100% solids, polyurethane based primer suitable for all substrates.
It is characterised by its very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on all substrates, whether of high, low or no porosity (e.g. glass and metals). Additionally, it can be effectively used on both dry and wet concrete, even green concrete, not only as primer but also as a low-cost sealing solution, increasing, thus, the durability of the substrate.

The cured film displays outstanding mechanical properties: Its elongation is 400%, i.e. it matches perfectly that of the HYPERDESMO® System, and its tensile strength surpasses 20 N/mm2.

Apply with brush or roller. Consumption: 100-500 gr/m2, subject to substrate porosity.

RECOMMENDED FOR:

To be used as primer for:

  • Humid, damp or wet concrete,
  • ceramic tiles,
  • other non-porous substrates like glass, marble & metals.

Also, for use as concrete sealer
