Application
N-(n-Butyl)-3-aminopropyltrimethoxysilane (CAS No. 31024-56-3), Silane coupling agent KH-558, is a bifunctional secondary amino-functional silane. It is an important additive for many applications. Examples are:
silane-endcapped Polyurethanes: Silane-terminated polyurethanes can be prepared by reacting traditional NCO-terminated urethane prepolymers with KH-558. It can react very fast with free isocyanate groups and lead to a high converted silane-endcapped product. Side reactions can be significantly reduced. KH-558 is the most recommended silane for endcapping Polyurethanes. It leads to colorless low-viscosity PU prepolymers with improved UV stability and reduced yellowing tendency of sealants. Another benefit of KH-558 is that it does not contain traces of toxic aniline.
Examples of applications where KH-558 used include polyurethanes for structural adhesives, parquet adhesives and over-paintable hybrid sealant.
glass fiber/glass fabric composites: as a finish or size constituent
mineral fiber insulating materials and abrasives: as an additive to phenolic resin binders
foundry resins: as an additive to phenolic, furan and melamine resins
sealants and adhesives: as a primer or additive and for chemical
