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+

Description

3-(Triethoxysilyl)propyl methacrylate (stabilized with BHT), 98% features a reactive methacrylate group paired with a triethoxysilyl handle, enabling covalent integration into silane-based matrices and polymer networks. The stabilizing BHT inhibits autoxidation during storage and processing. This bifunctional monomer facilitates durable crosslinking in hybrid organic-inorganic materials under mild conditions.

Application

3-(Triethoxysilyl)propyl methacrylate (stabilized with BHT) functions as a versatile silane-containing monomer enabling robust grafting onto inorganic surfaces and integration into hybrid organic-inorganic materials. Its triethoxysilyl group hydrolyzes readily to form silanol functionalities, facilitating covalent bonding to glass, silica, and metal oxides. The pendant methacrylate moiety supports free-radical polymerization, making it ideal for creating surface-anchored polymer coatings or functionalized nanomaterials. Bench-stable and compatible with standard reaction conditions, it facilitates scalable fabrication of advanced composite materials.
