Primers

MICROPRIMER-PU

MICROPRIMER is a one component, low viscosity, 100% aliphatic polyurethane based primer suitable for all substrates.

It is characterised by its very low viscosity, excellent impregnation, non-yellowing (non-staining) properties combined with a relatively fast cure speed and most importantly its excellent adhesion on both non-porous and porous substrates.

MICROSEALER-50

Microsealer 50 is a one component, solvent based low viscosity, polyurethane based primer suitable for many different substrates.

It is characterised by its very low viscosity and balanced curing speed which result in excellent wetting, impregnation and paint-over time on different 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.

MICROSEALER-PU

MICROSEALER-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.

AQUADUR

AQUADUR is a two-component, water based, epoxy coating. It has a track record of more than 20 years of successful use as primer for the HYPERDESMO® line of products, as well as other Alchimica polyurethane based products.

It is certified as "Class III” water and humidity barrier, which makes it ideal for applications subject to negative pressure / rising humidity.

An easy to use and safe (zero VOC) product with many applications besides priming.

Use as:

  • Primer in applications with rising humidity / negative pressure (tanks, pools, foundations etc.),
  • primer for other systems, e.g. epoxy or polyurethane based, cementitious,
  • sealing coat for concrete,
  • adhesive layer between old and new concrete,
  • water / humidity barrier.

UNIVERSAL PRIMER-2K-4060

UNIVERSAL PRIMER-2K-4060 is a two-component, solvent-less primer, for use with the HYPERDESMO® Systemand other polyurethane based products within the ALCHIMICAline-up.

It is fast-curing and non-toxic (has zero V.O.C.). Specially formulated for ensuring strong adhesion on humid or damp concrete.

To be used as primer for:

  • General use,
  • metals (also galvanized), aluminium, marble,
  • strengthening interlayer adhesion,
  • application under conditions of insufficient ventilation,
  • asphalt and asphaltic membranes,
  • οther, non-polyurethane based systems, e.g. acrylic paints.

PRIMER-PU

Polyurethane, one component primer.

Used for improving adhesion on porous substrates like beton, wood, plaster etc.

PRIMER-T

PRIMER-T is one component, colorless, non-staining primer especially designed to secure the adhesion of PRIMER-T on non-porous substrates. Although designed for HYPERDESMO®-T, it is fully suited for all products in the HYPERDESMO® product range.

PRIMER-T is easily applied by wetting a clean cloth and essentially cleaning the surface to be protected with HYPERDESMO®-T. PRIMER-T dries quickly, within 10-15 max. the surface is ready for application.

Recommended for priming of non-porous substrates:

  • Glassy tiles
  • glass
  • Slightly porous marble
