Silane-modified Polymers (MS/SMP/SPU)

Extra adhesive strength for demanding applications

Silanes are mandatory ingredients in SMP technologies for three functional reasons: Silanes are primarily used as efficient adhesion promoters to a wide variety of similar and dissimilar substrates, even to critical plastic substrates. Secondly, silanes are essential building blocks in the SMP binder itself. And thirdly, silanes act as effective moisture scavengers to increase storage stability of the corresponding adhesive & sealant (A&S) product. Such SMP adhesives show their strengths in e.g. flooring applications, since they increase the adhesion power between parquet and mineral substrates during service lifetime. The silane-based A&S products are also in demand for bonding and sealing in industrial assembly (e.g. washing machines and dryers).

Known as DYNASYLAN®, the silanes from Evonik combine several favourable features in SMP. They ensure improved adhesion to various substrates like wood, plastics and metal. Their high tensile strength and elasticity enables so-called elastic bonding as well as elastic movement joints. Finally, Evonik’s silanes help the adhesive to last longer, and therefore have a long service life.
