Sealforce Sealer Technology

Flouropolymer – Impregnations

Sealforce TechnologySealforce uses newly developed impregnation sealers that are an ingenious solution for surface protection for porous building materials. On the basis of the newly opened technology fields in the nanometre range, one of the most significant technologies of the 21st Century. Sealforce uses sealers that have successfully changed the architecture of the nano-scale (the very smallest) unique structures of the active molecules.  

Sealforce Technology - hydrophob and oleophobSealforce’s sealers produce new macroscopic functions, or, in other words, an almost perfect surface protection. To be more specific these are molecules in the range of several millionths of a millimetre. Millimetre for millimetre, thousands and thousands of molecules ensure long-term dirt and graffiti protection on the outer and the inner sides (surfaces of the capillary system / the pores) of porous mineral surfaces. The molecules not only protect the surface beneath, but also their own structure, and thereby their own long-term existence. The reason for this lies in the self-organizing molecules, which take up an identical alignment.

How it works:
In this nanotechnology, the surface energy of the substrate to be protected is modified in such a way that it is always lower than the surface tension of any possible contaminating liquid.

The multi-functional molecules consist of acryl copolymers with various side-chains, which complete various tasks. Please see diagram of “stick men” to help demonstrate:

  • The “Hats” consist of CF2 chains (fluorinated groups with strong CF3 ends). They ensure the low surface tension and thereby the protective effect.
  • The “Arms” are non-ionic groups. They guarantee the alignment and the linkage of the stick-men among each other.
  • The “Legs” are silane groups – they enter into a firm connection with the mineral sub-surface, and ensure a strong and permanent hold.

It is thereby ensured that the protective part of the molecule is at right angles to the surface (the pores), hence an optimal protective effect is obtained.
