Import 3-Isocyanatopropyltrimethoxysilane — Buy in wholesale FOB from Supplier in China

3-Isocyanatopropyltrimethoxysilane (CAS 15396-00-6, molecular formula C7H15NO4Si) is a colourless transparent liquid organosilane coupling agent supplied by Huangshan Kbr Chemical Co., Ltd. from Anhui Province, China. The product exhibits a density of 1.084 g per ml at 25 degrees Celsius, a refractive index of 1.421, and a boiling point range of 95 to 98 degrees Celsius. Its acidity is neutral with pH 6 to 7, and purity is stated at 98.5 percent minimum.

This silane contains an isocyanate group attached to a propyl linker and a trimethoxysilane moiety, enabling dual reactivity with both organic polymers and inorganic surfaces. The trimethoxysilyl group hydrolyses to form silanol groups that condense with metal hydroxides or silica, while the isocyanate functionality reacts with amines, alcohols, and other active-hydrogen compounds typical in polyurethane and epoxy systems. Standard storage requires tightly sealed containers under nitrogen or dry atmosphere to prevent premature hydrolysis and isocyanate dimerisation.

Primary applications span epoxy-functional coupling where storage-stable adhesion promotion without yellowing is critical, including coatings, adhesives, sealants, and composite materials. Buyers are typically formulators in automotive coatings, construction chemicals, and electronics encapsulation. Packaging options include 10 kg pails, 25 kg pails, 200 kg steel drums, 1000 litre IBC tanks, and 20 MT bulk tank deliveries. The supplier offers custom packing on request. Response rate data is currently unavailable, so buyers should establish direct contact to confirm lead times, Incoterms, and certificate of analysis availability.

Huangshan Kbr Chemical Co., Ltd. is located in Huangshan City, Anhui Province, China, with postal address 245000. The company operates under a harbour trust tier classification within the marketplace. The supplier lists a response rate of 0.00 percent and zero average response hours, which indicates no recorded inquiry activity or alternatively a data tracking gap rather than operational status.

The listing provides product-level data including CAS registry number, molecular formula, and technical specifications, but omits company-specific details such as year established, registered capital, production capacity, export licence status, quality management certifications, and named clientele. Buyers should request a business licence copy, ISO certification status, and past export references directly. The address in Huangshan, a region known for chemical and pharmaceutical manufacturing, suggests proximity to established raw material supply chains for organosilane production.
