Siltech – Silicone Quats and Silane Quats for Coatings and Anti-Bacterials
Siltech offers 3 main categories of silicone quaternary compounds (or “quats” for short), under the Silquat® trademark.
- Firstly, there are silicone dialkyl quats, where the alkyl group can be C2 or C18. Most of these are clear amber liquids, consisting of 70% silicone quat and 30% hexylene glycol. The structure can be multi-functional or linear di-functional, and multi-functional is shown below:
“a” and/or “b” can be changed in order to change the amount of hydrophobicity and solubility.
For Coatings applications, these products can be used to:
- Provide surface slip
- Impart excellent water and solvent repellency
- Add anti-static properties
- Impart softness
- Secondly, there are silicone polyether fatty quats, which have the following structure:
As shown, the fatty group can range from lauric (C12) to stearic (C18).
These products are low in viscosity, and are 40% active in water.
- Thirdly, there are silane quats, as shown below:
- This particular product is water-soluble, and can potentially be used in situations where anti-bacterial surfaces may be required.
The molecule is reactive, and can be methoxy or ethoxy-functional. This means that it can be reacted into coatings and onto surfaces for substantivity too.
