LS-AV31 γ-Aminopropyl-N-cyclohexylmethyldimethoxysilane 1130

Silfluo LS-AV31 is 3-[2-(2-Aminoethylamino)ethylamino]propyltrimethoxysilane, a triamino-functional organosilane.

The molecule contains one primary amine, two secondary amine groups, and one trimethoxysilyl group.

The amine groups react or interact with compatible resin systems including phenolic, furan, melamine, epoxy, polyurethane, and other thermosetting systems.

The trimethoxysilyl group hydrolyzes and reacts with hydroxylated inorganic surfaces including glass, silica, mineral fillers, and metal oxide surfaces.

Higher amine functionality than mono-amino or diamino silanes; used where stronger resin interaction or higher amine content is required.

Used as coupling agent, adhesion promoter, or reactive additive in thermosetting resin composites, adhesives, sealants, foundry binders, coatings, and mineral surface treatment systems.

Performance equivalent to Momentive Silquest A-1130 / Y-5621 and Evonik Dynasylan TRIAMO.

Applications of LS-AV31 γ-Aminopropyl-N-cyclohexylmethyldimethoxysilane 1130


1. Thermosetting resin composites

Used as coupling agent or reactive additive in phenolic, furan, melamine, urea-formaldehyde, epoxy, and other thermosetting resin systems. Verify mechanical properties, moisture resistance, and processing behavior by formulation testing.

2. Adhesives and sealants

Used as adhesion promoter in polyurethane, epoxy, acrylic, silicone, and hybrid adhesive or sealant systems. Verify adhesion to glass, metal oxide surfaces, mineral substrates, and plastics by substrate-specific testing.

3. Foundry sand binders

Used as coupling additive in phenolic, furan, and other foundry binder systems. Verify sand strength, humidity resistance, gas evolution, casting surface quality, and processing window under customer process conditions.

4. Coatings and primers

Used in coating and primer systems requiring amine functionality and alkoxysilane reactivity. Verify compatibility, adhesion, and film properties in the target formulation.

5. Glass fiber and mineral surface treatment

Used for glass fiber, silica, silicate, and mineral filler surface treatment. Verify filler-resin interaction, dispersion, and composite properties by application testing.
