Alsan® 170 Primer

Alsan® 170 Primer is a PMMA based, fast-curing, filled scratch-coat primer used as a barrier on highly absorbent mineral substrates in preparation for the later application of Alsan® PMMA resins.


Alsan® 170 is specifically designed for use on highly porous substrates. Alsan® 170 is also used for pre-treatment (primer and barrier) of absorbent, mineral substrates with large pores and pinholes in preparation for the later application of Alsan® PMMA resins.


- Optimum filling of pores and pinholes
- Minimal run-off on vertical surfaces
- Very good adhesion on absorbent substrates
- Fast-curing
- Hydrolysis and alkali resistant
- Solvent free


2-component, fast-curing PMMA based (polymethyl methacrylate) scratch-coat primer, made thixotropic and filled with quartz sand. Alsan®170 is unpigmented.

  • Application equipment / tools:
    - Mixing of the product: suitable mixer (ex. paint mixer)
    - Applying of the product: smoothing trowel
  • Substrate preparation:
    ® 170 must only be applied to a prepared substrate. Please refer to the appropriate application guide for information about correct surface preparation.
  • Mixing:
    - First stir the tub contents thoroughly.
    - Then add the catalyst whilst stirring at a low speed for 2 minutes.
    - Make sure that all material on the side and base of the pot is mixed in.
    - At temperatures below 10 ªC the product should be stirred for 4 minutes as the catalyst will take longer to dissolve.
  • Application:
    - Use a smoothing trowel to apply an even, film forming layer of primer.
    - Avoid creating any build-up of material.
    - Once the coating has cured, apply a second coat to cover any defects (bubbles, areas not fully coated).
