1.Product Introduction of the N-(3-(Trimethoxysilyl)propyl)butylamine(CAS:31024-56-3)

N-(3-(Trimethoxysilyl)propyl)butylamine(CAS:31024-56-3), Our model SCA-A64M (equivalent to 1189 of evonik),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.

Soluble in alcohol and aromatic and aliphatic hydrocarbons. React with water.

3.Application of the N-(3-(Trimethoxysilyl)propyl)butylamine(CAS:31024-56-3):

N-(n-Butyl)-3-aminopropyltrimethoxysilane (CAS No. 31024-56-3), silane coupling agent SCA-A64M, is a bifunctional secondary amino-functional silane. It is an important additive for many applications. Examples are:
1. Silane-endcapped Polyurethanes: Silane-terminated polyurethanes can be prepared by reacting traditional NCO-terminated urethane prepolymers with SCA-A64M. 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-A64M 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-A64M is that it does not contain traces of toxic aniline.
Examples of applications where SCA-A64M used include polyurethanes for structural adhesives, parquet adhesives and over-paintable hybrid sealant.
2. Glass fiber/glass fabric composites: As a finish or size constituent
3. Mineral fiber insulating materials and abrasives: As an additive to phenolic resin binders
4. Foundry resins: As an additive to phenolic, furan and melamine resins
5. Sealants and adhesives: As a primer or additive and for chemical modification
6. Mineral-filled polymers (composites) or HFFR cables: For pretreatment of fillers and pigments
7. Paints and coatings: As an additive and primer for improving adhesion to the substrate.
8. As a primer for glass and metal.
