Abstract
Bis(trimethoxysilylpropyl)amine (CAS No. 82985-35-1), Silane coupling agent KH-170, is a versatile amino functional coupling agents used over a broad range of applications to provide superior bonds between inorganic substrates and organic polymers. The secondary amine function reacts with a wide array of thermoset, thermoplastic and elastomeric materials. Identification Name: Bis(trimethoxysilylpropyl)amine Synonyms: 3, 3'-Bis(trimethoxysilyl)dipropylamine; 3-(Trimethoxysilyl)-N-(3-(trimethoxysilyl)propyl)-1-propanamine Molecular Formula: C12H31NO6Si2 Molecular Weight: 341.55 CAS Registry Number: 82985-35-1 EINECS: 280-084-5 Equivalents Momentive (formerly OSi Specialties ) Silquest A-1170 EVONIK Degussa Dynasylan 1124 Properties Density: 1.04 Boiling point: 285 C degree Water solubility: REACTS Application Bis(trimethoxysilylpropyl)amine (CAS No. 82985-35-1),
Silane coupling agent KH-170, 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-170.
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-170 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-170 is that it does not contain traces of toxic aniline. Examples of applications where KH-170 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 modification Mineral-filled polymers (composites) or HFFR cables: For pretreatment of fillers and pigments Paints and coatings: As an additive and primer for improving adhesion to the substrate. As a primer for glass and metal.
