If you’re looking for exceptional wetting agents that are efficient at low end-use concentrations, talk to Chemlink Specialities about Thetawet short-chain fluorosurfactants.

Why Thetawet? 

Often used along with traditional and specialty surfactants, Thetawet FS-series short-chain fluorosurfactants deliver maximum performance and efficiency. 

Thetawet grades are stand-out because:

  1. They lower surface tension to levels below what’s achievable with other surfactants (< 20 dynes/cm)
  2. They have a broad range compatibility with other additives
  3. They are stable at extreme pH and with a high loading of additives
  4. They can improve the overall performance of your end product

Chemlink Specialities are pleased to supply three highly effective Thetawet grades, each with a wide range of applications for HI&I formulators.

Thetawet  Ionic Type  Form  % Solids  Diluent 
FS-8050  Nonionic  Liquid  50  Water 
FS-8150  Nonionic  Turbid liquid  25  Water 
FS-8250  Anionic  Turbid liquid  28  Water 

Thetawet FS-8050

Thetawet FS-8050 is a VOC-free, water-soluble nonionic ethoxylated fluorosurfactant with 50% actives. It offers outstanding wetting of low-energy substrates such as plastic, metal, glass, oily substrates, waxy surfaces, fluoropolymer and silicone treated fabrics. Thetawet FS-8050 is a foaming product. 

Thetawet FS-8150

Thetawet FS-8150 is a VOC-free nonionic fluorosurfactant that offers excellent surface tension reduction when used at levels of 0.01 to 0.1%. It performs well in severe thermal and chemical environments and is low foaming. We recommend use of no more than 0.25% in formulations due to limited water solubility.

**Thetawet FS-8150 also has anti-fogging properties, so can be used to impart (or even boost) anti-fog properties of things like glass cleaners – ideal for the current climate in which many people are struggling to wear masks and glasses together because of fogging.**

Thetawet FS-8250

Thetawet FS-8250 is a VOC-free, anionic fluorosurfactant which provides anti-blocking in paints and release properties to adhesives. It is a very low foaming product, giving excellent wetting and leveling benefits.
