Thetawet™ FS-8100

• Sparingly water-soluble nonionic fluorosurfactant effective at low end-use concentrations (10-100 ppm typical)
• Exceptional surface tension reduction for wetting low-energy substrates such as plastic, metal and glass
• Optimized for surfactant performance, Thetawet short-chain technology meets or exceeds performance of long-chain products
• 100% active material ideally suited for non-aqueous and many solvent reducible applications
• Nonionic character allows compatibility with all surfactant types.
• Effective in high or low pH, hard or soft water
• Stable in concentrated acids, bases and oxidizing solutions
• Narrow-range ethoxylation for high consistency in critical-use applications such as ink-jet media

• Immediately prior to use, if necessary, warm the Thetawet™ FS-8100 until the material becomes a free-flowing clear liquid and mix well, in order to ensure uniformity.
• Dramatic surface tension reduction of all types of aqueous systems can be achieved with the addition of 0.001 to 0.05% of Thetawet™ FS-8100.
• It performs well and is stable in severe thermal and chemical environments (strong acid, base or oxidizing solutions).
• Low surface tensions can be achieved in both highly alkaline and highly acidic systems.

• Through extensive product development, applications research and manufacturing optimization, Thetawet™ FS-series short-chain fluorosurfactants deliver performance on-par with long-chain alternatives.
• Often used along with traditional and specialty surfactants, Thetawet™ FS-series short-chain fluorosurfactants deliver maximum performance not achievable with traditional and specialty alkyl, acetylenic diol and silicone surfactants alone.
• Thetawet™ FS-series short-chain fluorosurfactants are exceptional wetting agents efficient at low end-use concentrations, typically in the 10-100 ppm range.
• Very low end-use concentrations allow for economical use and often eliminate re-wet properties characteristic of the higher end use concentrations required with traditional and specialty surfactants.

• Physical Scientists assigned the Greek Letter Theta θ to represent the angle formed by a liquid at the three phase boundary where a solid, liquid, and gas intersect.
• It is also known as the contact angle.
• The measurement of Theta is the means by which we can quantify both how well a liquid can wet out a surface, or by contrast, how well a surface can resist being wetted.
• The manipulation and control of Theta is critical in the design of effective oil, water, and stain repellents, and the reduction of surface tension necessary to make improved coatings and cleaning products.
• As illustrated below, a decreasing θrepresents increasing wetting and adhesiveness, and an increasing θrepresents increasing repellency.
• It is only fitting that ICT chose Theta θ to represent these new and exciting products.
• Thetawet™ FS-8100 is an excellent choice for wetting difficult to wet low energy surfaces such as plastics, oily substrates, waxy surfaces, and silicone and fluoropolymer treated fabrics.
• The ability of FS-8100 to lower the aqueous surface tension of liquids, allows those liquids to wet low energy surfaces.
• By contrast, typical alkyl surfactants, at any concentration, will only lower aqueous surface tension to about 30 dynes/cm, meaning that a typical alkyl surfactant solution will not wet a 25 dynes/cm surface, resulting in lack of coverage, incomplete leveling or inadequate cleaning performance.

• Demonstrated above, the surface tension of aqueous solutions and emulsions can be reduced to 18 dynes/cm with Thetawet™ FS-8100.
• This low surface tension results in better wetting, spreading, and penetration which translates into improved film uniformity, enhanced adhesion, reduced pinholes and craters for coatings, improved spreading for reduced water spotting, and smoother and more even films for finishes and polishes.
• It also translates into better wetting and penetration of cleaning solutions which makes them more effective.
• Thetawet™ FS-8100 provides far greater surface tension reduction than can be achieved with either hydrocarbon or silicone based surfactants.
• When used in conjunction with “conventional” hydrocarbon surfactants, it is possible to achieve a system that not only dramatically reduces surface tension, but also lowers interfacial tension resulting in a liquid that easily wets and spreads on otherwise hard to wet surfaces.
