1.Product Introduction of the Bis(trimethoxysilylpropyl)amine(CAS:82985-35-1):

Bis(trimethoxysilylpropyl)amine(CAS:82985-35-1), Our model SCA-A67W (equivalent to Silquest® A-1170), 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.

2. Product Parameter (Specification) of the Bis(trimethoxysilylpropyl)amine(CAS:82985-35-1):




Colorless to slight yellow, transparent liquid

Specific Gravity (ρ20), g/cm3


Boiling Point (760mmHg), ℃


Refractive Index


Flash Point, ℃



Completely and immediately soluble in alcohol and aromatic and aliphatic hydrocarbons. Ketones are not recommended diluents. Will react with water.

3.Application of the Bis(trimethoxysilylpropyl)amine(CAS:82985-35-1):

Bis (trimethoxysilylpropyl) amine (CAS No. 82985-35-1), Silane coupling agent SCA-A67W, 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 SCA-A67W. It can react very fast with free isocyanate groups and lead to a high converted silane-endcapped product. Side reactions can be significantly reduced. SCA-A67W 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 SCA-A67W is that it does not contain traces of toxic aniline.

Examples of applications where SCA-A67W 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.
