ATLAS Stopter K- 50

Adhesives and Basecoats - AVAL

ATLAS Stopter K- 50

 Description Suitable for the installation of different types of thermal insulation panels and the subsequent execution of a reinforced layer - the adhesive can be used with expanded polystyrene (white, graphite-enhanced and with addition of graphite) and with mineral wool (facade and lamella).
A perfect solution for projects using thermal insulation panels of different materials.
No priming masses under renders required - the unique structure of hardened adhesive creates a layer that provides a strong bond to thin-coat render, and white cement minimizes the risk of discolouration on the render surface. The main characteristics • white
• no bonding layer required
• for mineral wool and expanded polystyrene
• for panel application and base coat installation
• also for graphite - enhanced EPS The main parameters • base coat bed thickness: 2 - 5 mm (on polystyrene); 4 - 6 mm (on mineral wool)
• consumption: EPS boards application: from 4.0 to 5.0 kg/m²
• consumption: base coat application: from 3.0 to 3.5 kg/m²
• consumption: MW panels application: from 4.5 to 5.5 kg/m²
• consumption: base coat application: from 5.5 to 6.5 kg/m²
• adhesion to concrete: min. 0.25 MPa
• adhesion to expanded polystyrene: min. 0.1 MPa
• adhesion to mineral wool: min. 0.08 MPa Base coat application: from 5.5 to 6.5 kg/m².

Availability: In stock

High flexibility – perfectly compensates thermal and mechanical stress exerted on other layers of the system.

Excellent adhesion – strongly bonds to problematic substrates, such as surfaces with well-bonded paint coats.

Water vapour permeability – does not restrict water vapour transmission through the insulated wall.

Very good working properties – during mixing, application to panels, mesh embedding etc.

ATLAS STOPTER K-50 is manufactured as a dry mix of top quality cement binder, aggregate and modifiers, reinforced with glass fibre.
