LS-E86 N-(3-(Triethoxysilyl)methyl)butylamine

Silfluo LS-E86 is N-(triethoxysilylmethyl)butylamine, an alpha-secondary amino functional silane.

The molecule contains a butyl-substituted secondary amine connected to silicon through a methylene bridge, and a triethoxysilyl group.

The alpha-silane structure gives different hydrolysis and condensation behavior compared with conventional gamma-functional silanes.

The secondary amine interacts with compatible resin systems and selected reactive polymers.

The triethoxysilyl group hydrolyzes and forms siloxane linkages or bonds to hydroxylated inorganic surfaces under suitable moisture, pH, and catalyst conditions.

Compared with primary aminosilanes, the secondary amine structure reduces yellowing tendency in selected clear or light-colored formulations; verify color stability in the target system.

Used as adhesion promoter, crosslinking additive, or reactive silane component in SMP, MS polymer, SPUR, RTV silicone, polyurethane, primer, coating, and adhesive systems.

Applications of LS-E86 N-(3-(Triethoxysilyl)methyl)butylamine


1. SMP, MS polymer, and SPUR systems

Used as adhesion promoter, crosslinking additive, or reactive silane component in silane-modified polymer and silyl-terminated polyurethane systems. Verify cure profile, catalyst demand, viscosity, modulus, elongation, adhesion, and storage stability in the final formulation.

2. RTV silicone systems

Used as adhesion promoter or crosslinking additive in room-temperature-vulcanizing silicone systems. Verify skin-over time, deep-section cure, adhesion, and color stability by formulation testing.

3. Polyurethane adhesives and sealants

Used as reactive silane additive in one-part and two-part polyurethane adhesive and sealant systems. Verify adhesion, moisture sensitivity, gelation behavior, and storage stability in the target formulation.

4. Primers and coatings

Used in primer and coating systems requiring secondary amine functionality and alkoxysilane reactivity. Test wet adhesion, dry adhesion, film compatibility, and corrosion resistance in the target system.

5. Adhesives and hybrid sealants

Used in adhesive and hybrid sealant systems requiring adhesion support and moisture-curing reactivity. Verify compatibility, cure behavior, and final mechanical properties before commercial use.
