    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.

Description

Octavinyloctasilasesquioxane delivers a highly functional silsesquioxane scaffold with eight pendant vinyl groups, enabling efficient crosslinking and integration into hybrid organic-inorganic materials. This cage-like structure combines thermal stability with tunable reactivity, facilitating straightforward incorporation into polymer matrices, coatings, and nanocomposites under mild conditions.

Application

Octavinyloctasilasesquioxane serves as a versatile building block in hybrid organic-inorganic synthesis, enabling efficient sol-gel processing and functionalization of silica-based materials. Its eight vinyl groups provide high reactivity in hydrosilylation and radical addition reactions, facilitating robust network formation. The cage-like structure offers excellent thermal stability, low volatility, and compatibility with polymer matrices, making it ideal for advanced coatings, nanocomposites, and porous materials.
