1.Product Introduction of the Bis[3-(triethoxysilyl)propyl]amine(CAS:13497-18-2)

Bis[3-(triethoxysilyl)propyl]amine(CAS:13497-18-2), Our model SCA-A67X , 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.

3.Application of the Bis[3-(triethoxysilyl)propyl]amine(CAS:13497-18-2):

Bis(triethoxysilylpropyl)amine (CAS No. 13497-18-2), Silane coupling agent SCA-A67X, 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-A67X. 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-A67X 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-A67X is that it does not contain traces of toxic aniline.  Examples of applications where SCA-A67X 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.

4.Packing Details of the Bis[3-(triethoxysilyl)propyl]amine(CAS:13497-18-2)):

The regular packing of Bis[3-(triethoxysilyl)propyl]amine(CAS:13497-18-2) is 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.
