Introduction

Polydimethylsiloxane (PDMS) is a polymer used in a variety of industries, including electronics and aerospace. It is favored for its low viscosity and excellent dielectric properties, but can sometimes be too viscous for certain applications. For those looking to lower their 107 OH-terminated PDMS viscosity, understanding the chemistry behind your product can provide you with the answers you need. In this article, we’ll explore the effects of crosslinking and other techniques that can help you lower your PDMS viscosity to get the most out of your product.

What is 107 OH-terminated PDMS?

When it comes to modifying the properties of PDMS, one common approach is to functionalize the surface with different groups. One such group is the hydroxy group, which can be introduced by hydrolyzing the Si-CH3 bonds in PDMS. This results in a material with a lower viscosity, which can be advantageous for many applications.

What is the structure of 107 OH-terminated PDMS?

Polydimethylsiloxane (PDMS) is a type of silicone polymer made up of repeating units of dimethylsiloxane. It is a clear, colorless, and odorless liquid with a variety of applications. OH-terminated PDMS has hydroxyl groups at the end of its polymer chain, which makes it more reactive than other types of PDMS. This allows it to be used in situations where it needs to bond with other materials or be cross-linked with other polymers. The structure of 107 OH-terminated PDMS is a long chain of alternating silicon and oxygen atoms, with hydroxyl groups attached to the end of the chain.

How to lower the viscosity of 107 OH-terminated PDMS?

If you need to lower the viscosity of your 107 OH-terminated PDMS, there are a few things you can do. One is to increase the temperature. This will cause the polymer chains to move around more and break apart some of the hydrogen bonds holding them together, which will lower the viscosity. Another is to add a plasticizer, which will also help break apart the polymer chains and lower the viscosity. Finally, you can also add a solvent, which will dilute the PDMS and also help break apart the polymer chains.
