Description

3-(n-Cyclohexylamino)Propyltrimethoxysilane is a bifunctional organosilane coupling agent that combines a reactive trimethoxysilyl group with a secondary amino group. This dual functionality makes it an essential component for modifying material interfaces, enhancing adhesion, and improving the dispersion of inorganic fillers in organic polymer matrices. It is particularly valuable for industries requiring durable, high-performance composite materials and coatings. The compound is supplied with CAS No. 3068-78-8.

Application

• As a coupling agent in fiberglass-reinforced plastics and mineral-filled composites to improve mechanical strength and moisture resistance.
• Surface treatment for silica, glass fibers, and other mineral fillers to enhance compatibility with epoxy, nylon, and phenolic resins.
• Key additive in sealants, adhesives, and coatings to promote adhesion to challenging substrates like metals and glass.
• Used in the formulation of tire tread compounds and other rubber goods to improve filler-rubber interaction and reduce hysteresis.
• Primer or additive for corrosion-resistant coatings on aluminum, steel, and other metals.
• Potential use as an intermediate in the synthesis of more complex silane derivatives for specialized applications.

Quality Control

Our production of 3-(n-Cyclohexylamino)Propyltrimethoxysilane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, purity, and identity confirmation, to ensure it meets precise customer and industry specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as purity, refractive index, and density.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from strong acids and bases.
