ATLAS ROKER W is manufactured as a dry mix of high quality cement binder, aggregates, polymer dispersions and modifiers.
Very high bonding – owing to the content of polymer dispersions, adhesive shows high adhesion to mineral and ceramic substrates and to mineral wool boards. This performance is additionally improved by mortar diversified tight aggregate mix. The mortar adheres well even to difficult substrates, e.g. surfaces coated with well bonded paints.
Great flexibility – greater content of dispersions increases mortar flexibility and allows for perfect compensation of stress resulting from thermal and operational pressure put on the system layers.
Improved resistance to cracking and scores – owing to structural fiber reinforcement the mortar offers improved resistance to:
• microcracking at initial phase of binding,
• cracking during system operational use.
Great water vapour permeability – does not limit water vapour permeability through partition which is particularly significant when system based on mineral wool insulation is in use.
Most important features
- for mineral wool
- very high bonding to difficult substrates
- very good workability
- water vapour permeability
