One-component sealant for roofing based on MS Polymer Tenalux 112M

Ready-to-use, one-component sealant based on MS Polymer for sealing joints and cracks in vertical and inclined building structures. Easy to apply manually by spraying using special guns. Can be used to seal joints in horizontal structures in the absence of mechanical stress. Cures due to chemical reaction with air moisture. The sealant has excellent adhesion to basic building materials, as well as good strength and deformation properties after hardening. Can be used in residential premises.

Areas of application:

- Roof sealing:
- sealing of joints at the junction of the roof and walls
- sealing around the perimeter of attic and dormer windows, mounting supports and brackets
- sealing of external joints on chimneys, ventilation outlets and drainage holes
- laying of perimeter elements of roofs (eaves, parapets, rain gutters, pipes, drainage holes)
- repair of roofing coverings
• Sealing of joints and cracks in vertical and inclined building structures in the absence of direct mechanical load
• Sealing of horizontal joints and cracks in the absence of direct mechanical load
• Sealing of expansion joints with a maximum deformation of ±20%

Advantages:

• Complies with EN 15651-1, type F, class 20HM – EXT – INT – CC
• Can be applied by spraying in wide temperature range
• Suitable for use in cold climate zones
• Excellent thixotropic, does not flow in vertical joints
• Excellent adhesion to the surfaces of most building materials
(Concrete, metals, polymer coatings, plastics, wood materials,
glass and bituminous roofing materials covered with crumb) without the use of a primer
• Excellent resistance to climatic factors, especially in
humid and hot conditions
• Maintains elasticity in a wide temperature range
• Can be painted with any water-dispersion paints
• Safe to use - does not contain isocyanates, silicones
and solvents
• Odorless
• Virtually does not shrink

Expansion joint installation

To prevent the formation of a third plane of contact between the sealant and the structural elements of the joint, it is always necessary to use anti-adhesion compounds or sealing gaskets, such as, for example, a polyethylene foam strap. To limit the depth of the sealant layer, achieve the recommended ratio of width and depth of the sealant, as well as to reduce material consumption, it is recommended to select the size of the sealing gasket taking into account the actual width of the joint. It is necessary to follow the recommendations for the optimal width and depth of the joint for this sealant. Applying a sealant with a layer thickness less than the minimum recommended leads to a decrease in the durability of the joint sealing. Exceeding the maximum recommended thickness of the sealant layer causes high internal stresses, which contribute to the appearance of cracks. Narrow joints must be enlarged using special tools to achieve the recommended width and depth. Joints that are too wide, as well as joints with a porous, weak surface, should be treated with appropriate repair compounds.

Surface preparation

The surface in contact with the sealant must be solid, clean and dry. The joint surface must be cleaned of all contaminants that reduce the adhesive strength of the bond with the surface.
