CAS 1067-25-0 — n-Propyltrimethoxysilane

n-Propyltrimethoxysilane is an organosilane coupling agent with a propyl functional group, used primarily for surface modification, adhesion promotion, and water-repellent coatings in materials like glass, metals, and plastics. It reacts with hydroxyl groups on substrates while hydrolyzing to form silanol groups, improving bonding and durability in composites, sealants, and adhesives. This chemical has a CAS number of 1067-25-0, carries no signal word under CLP/GHS classification, and is a clear, colorless liquid with a mild odor. It is typically stored under dry conditions to prevent premature hydrolysis. Molekula supplies n-Propyltrimethoxysilane from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
