uah / PCS.

Tenalux 131 M is a ready-to-use one-component sealant based on MSPolymer® for sealing joints in horizontal structures with direct mechanical load. It can be used for sealing joints in vertical and inclined building structures. It is easily applied manually by syringing using special pistols. It cures as a result of a chemical reaction with air moisture. The sealant has excellent adhesion to most building materials, as well as good strength and deformation qualities after curing. It can be used in residential areas.

Advantages:thixotropic (does not drain in vertical seams)

high level of adhesion to concrete surfaces, metal, wood, plastic and glass
it is used in a wide temperature range, while maintaining good elasticity
resistant to climatic factors
it can be painted with water-dispersion paints
practically does not shrink
environmentally friendly (can be used in residential areas)

TENALUX 131 M is a ready-to-use one-component sealant, developed on the basis of MS polymer (silane modified polymer) in the form of a gray thixotropic mass. It is used for sealing joints, seams and cracks on horizontal, vertical and inclined building surfaces with a maximum deformation of ± 25% under increased regular and irregular mechanical loads. It has a high level of adhesion to various surfaces of building materials, as well as good strength and deformation characteristics after polymerization.

Application:sealing of joints of industrial floors

sealing joints of vertical and inclined construction structures
sealing of joints in horizontal building structures
sealing of expansion joints with a maximum deformation of ± 25% under regular and irregular mechanical loads

How to properly apply sealant?

The surface must be solid, clean and dry. Therefore, before applying the sealant, the treated surface must be cleaned of all contaminants that reduce adhesion. If necessary, all surface defects, cracks and chips should be leveled using TEKNO repair compounds.

The sealing mass is applied manually using special syringes (pistols). The sealant cures as a result of a chemical reaction with air moisture. To prevent the sealant from coming into contact with the structural elements of the seams, it is necessary to use a bundle of foamed polyethylene or anti-adhesive compounds.

How is the expansion joint installed?

To prevent the formation of a third plane of contact of the sealant with the structural elements of the seam, it is always necessary to use anti-adhesive compounds or sealing gaskets, such as, for example, a bundle of foamed polyethylene. 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 seam. In addition, the use of cellular sealing materials reduces heat loss and improves sound insulation performance. It is necessary to follow the recommendations for the optimal width and depth of the seam for this sealant. Applying the sealant with a layer thickness less than the minimum recommended leads to a decrease in the durability of the sealing seam. Exceeding the maximum recommended thickness of the sealant layer causes high internal stresses that contribute to the appearance of cracks. Narrow seams need to be enlarged with special tools to achieve the recommended width and depth. Seams that are too wide, as well as seams with a porous, fragile surface, should be treated with appropriate repair compounds.
