|Harcros Organics offers a broad range of nonionic surfactants under the T-Det trade name. These products are manufactured by reacting alkylene oxides with various oils, fatty acids, alcohols and alkylphenols. The table below illustrates some of the products we offer. Harcros offers custom and toll alkoxylation service as well.|
|T-Mulz® is the registered trademark for Harcros Organics line of phosphated alcohol and alkyl phenol ethoxylates. These materials are available as mono-ester and di-ester rich grades, and are useful for the dispersion and emulsification of various organic and inorganic compounds under difficult conditions. Applications would include dispersing highly hydrophobic materials into aqueous conditions, such as making polymers for aqueous emulsion paints, and stabilizing various dispersion/emulsions under acid or alkaline conditions.|
|Harcros' Emulzymer products are very specialized emulsifiers for emulsion polymer systems. Chemistries include sodium and ammonia ether sulfates as well as phosphate esters of various alcohols and alkoylated products. These products are tailored for each specific emulsion system. Properties that can be modified include: alcohol chain, degree of alkoxylation, cloud point, free non-ionic, sodium or ammonia salt, free sulfate or phosphate content and more.|
|The proper selection of a foam control additive is dependent on many factors from the foaming media to food contact approvals. For additional information on Harcros Organics foam control additives please see your local Harcros representative or contact Harcros Organics.
Harcros Organics produces a full line of silicone-based antifoams for both food and industrial applications. Harcros “AF” silicone antifoam compounds and emulsions are high quality antifoams that are proven to provide the consistent foam control performance in a variety of environments and foam make up. A direct food additive or process aid, Harcros Organics produces consistent performing antifoams. Food Grade and Kosher certifications are available in addition to Kosher for Passover in special order requirements. Harcros “AF” antifoams are proven effective in many industrial applications where there are changing conditions and multiple foam sources.
|For applications where a non-silicone foam control additive is needed Harcros Organics produces our “HL” and “GN” series of antifoams. From coatings for food packaging to industrial water treatment, Harcros produces high actives foam control additives based on hydrocarbon, polypropylene glycol and low foam surfactant technology. All of Harcros non-silicone foam control additives have indirect food contact approvals. Additives for water based latex paints or for UV/EB cure Harcros can recommend a foam control additive specifically for your application.|
|Harcros “M” series antifoams are based on food grade ingredients and perform well in many food and industrial applications. The new antifoams have faster more effective knock down for existing foam and are superior formulation aids when foam prevention is essential. The antifoams contain a higher viscosity silicone fluid and high performance additives to extend their performance long after traditional silicone antifoams have lost their effectiveness.|
|Harcryl® is the registered trademark for Harcros Organics line of reactive acrylic monomers. These are comprised of a line of phosphated or boronated acrylic monomers used as a component of polymers for paints and other coatings. When included in such polymers,Harcryl® monomers improve adhesion to difficult substrates, improve fire retardancy, and help reduce corrosion. They are also used in radiation curable compositions, where they also improve adhesion, flexibility, and improve curing rates. Typical inclusion rates are from 2 to 8% of the polymer composition.|
|H-Sperse® is the registered trademark for Harcros Organics line of ionic and non-ionic dispersant materials. The line is comprised of various aliphatic alcohols and alkyl phenols, which have been alkoxylated for their particular applications. The non-ionic materials have been found to be particularly useful for the dispersion of carbon blacks. The ionic grades are phosphated or boronated versions of the non-ionic dispersants, and are useful for dispersing metal and metal oxide materials in difficult conditions. This is because the finished dispersions are essentially non-ionic, and insensitive to acid or alkaline pH conditions.|
