WIDOCRYL-Concrete Primer PM
is a low viscosity, colorless, 2 component reactive resin consisting of methyl methacrylate (MMA), and hardener powder. WIDOCRYL-Concrete Primer PM
WIDOCRYL-Concrete Primer is used as a special priming coat with very good adhesion on damp concrete substrates. We strongly recommend with all WIDOCRYL-Primers that curing and adhesion tests are conducted on particular substrate prior to general use on site.
Product Information Downloads Basis Methyl methacrylate resin Consumption approx. 400 - 700 g/m² depending on porosity of the substrate
Pot life approx. 15 min. at +20°C Curing time (curing with hardener) approx. 30 min. at +20°C Packaging unit 10,00 kg Minimum working temperature -5°C Temperature resistance - 20°C to + 80°C (after curing)
Cleaning in fresh state WIDOPAN-Cleaner Storage If container is kept closed and storage temperature held constantly between + 15°C und + 20°C, the product may be used for up to 6 months.
The surface must be solid and free of dust, fat and oil. Loose and hollow tiles must be removed. Laitance and loose particles must be removed thoroughly, e. g. by shot blasting.
It should be noted that the amount of catalyst powder to be added depends upon the substrate temperature. For further details, see container lid.
The primer should be applied as a sealed film with blanket coverage and in principle should be sprinkled with quartz sand of grain size 0.3 – 0.8 mm. If this cannot be achieved within one working process, a second priming layer has to be applied (note: only the top layer should be sprinkled with quartz sand).
Further details, especially regarding hazard statements, security advices and measures in the event of fire can be found in the safety data sheet under sections 2, 4, 5, 6, 7 and 8.
