HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

Decyltrimethoxysilane features a long hydrophobic decyl chain paired with three methoxy groups, enabling robust surface anchoring via silanol condensation. This structure delivers durable, moisture-resistant monolayers on silica and metal oxide substrates, ideal for modifying sensor surfaces, microfluidic channels, and lab-on-a-chip devices.

Application

Decyltrimethoxysilane serves as a versatile silane coupling agent, enabling robust surface modification of inorganic substrates through hydrolytic condensation. Its long alkyl chain imparts hydrophobicity and stability in aqueous and organic environments, making it ideal for creating durable, low-surface-energy coatings on silica, glass, and metal oxides. The molecule facilitates controlled grafting with excellent functional group tolerance and minimal side reactions, supporting applications in chromatography columns, anti-reflective coatings, and microfluidic device fabrication.
