ALSAN 176

Alsan® 176 is a PMMA based, fast-curing, filled scratch-coat primer.

Description

Alsan® 176 is used as a barrier on highly absorbent mineral substrates in preparation for the later application of Alsan® PMMA resins. Alsan® 176 is specifically designed for use on highly porous substrates.

Properties:

- 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

Implementation

Application equipment / tools:
- Mixing of the product: suitable mixer (ex. paint mixer)
- Applying of the product: smoothing trowel

Substrate preparation
:
Alsan
® 176 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 °C 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).

Packaging
