The all-rounder: sealant
Experience has shown that sealants are subjected to particularly high loads. Mechanical stress when walking or through the furniture, physical changes through thermal influences, chemical attacks and cleaning agents - sealants have to withstand a lot. Modern sealant systems, including our CF MULTI, have so-called silane-modified polymers as their base material. Silane-modified polymers (also called MS polymer) combine the positive properties of a polyurethane with those of a silicone in one product and harden through a chemical reaction with the humidity in the air. This creates an elastic adhesive and sealing connection. The advantages of this technology are obvious: they have good UV resistance and shrink only slightly, are free of solvents, PVC and isocyanates and are odorless. Without solvents, they are virtually odorless, which makes working in smaller spaces easier. In addition, MS polymers do not require an additional work step after cleaning because they are used without a primer. The primer (primer = adhesion promoter for difficult substrates), which normally has to be applied separately, is built into the sealant. The sealant application actually includes two work steps, primer application and sealant application itself. The sealant and adhesive can be painted over and painted over. An application on slightly damp surfaces is also not difficult.
The universal applicability and the advantages described are the reason for the growing importance of this sealant class, also for do-it-yourself applications. MS polymer sealants are therefore suitable for the entire construction sector for connection and expansion joints indoors and outdoors, for example for joints on windows, doors, in the roof area, seals in wood, metal construction or sanitary areas. It is also suitable for elastic bonding.
