TEXIPOL®63-202 is an inverse emulsion thickener that imparts pseudoplastic rheology to aqueous-based compositions. TEXIPOL 63-202 can be used to thicken a wide variety of aqueous binder systems including; PVA, VAE, SBR, PVdC, and acrylic and styrene-acrylic copolymers. It has been used in various adhesive, sealant, and coating formulations. It can thicken systems as low as pH 5 but is most efficient at pH>7. Typical thickener dosages are probably 0.5-2.0%, though this is system-dependent and higher paste viscosities may require higher addition levels.

TEXIPOL®63-513 is a next-generation inverse emulsion synthetic thickener based on a significant proportion of bio-derived content which imparts pseudoplastic rheology to aqueous compositions and is supplied as a pre-neutralized dispersion as the sodium salt of an acrylic-based polymer. It has broad pH compatibility (4-12).

TEXIPOL® 63-510 is an inverse emulsion thickener that imparts highly pseudoplastic rheology to aqueous-based compositions. It is supplied as a pre-neutralized dispersion as the sodium salt of an acrylic copolymer and shows thickening over a very wide pH range of 2-12. It can thicken both acidic and alkaline compositions and gives stable thickening in various organic acids such as citric and glycolic acid. It will also thicken phosphoric acid effectively. Thickening is normally achieved quite quickly, but in stronger acid and alkaline environments, maximum thickening may take somewhat longer. TEXIPOL® 63-510 has been used to thicken various water-based adhesives and coating systems where it gives an exceptionally creamy consistency. It has also been possible to thicken aqueous blends with N-methylol pyrollidone and other polar solvents. Typical thickener dosages are 0.5-2.0%, though this is system-dependent and higher paste viscosities may require higher addition levels.

TEXIPOL® 63-237 is a multifunctional inverse emulsion thickener developed specifically for the pigment printing of textiles. It provides an outstanding print definition as well as superb fastness properties, color yield, brightness, and excellent softness of handle. It may be used on a variety of textile substrates including 100% cotton, polyester, poly-cotton, and other synthetic fibers and blends. It is normally used at 3.0-4.0% of the print paste and the standard addition level is 3.5%. It is compatible with all the typical print paste ingredients including preservatives, humectants, antifoams, softeners, binders, and cross-linking additives. TEXIPOL® 63-237 is suitable for use on hand screens, rotary and flat-bed printing machines. It has also found use as an effective thickener in a variety of other applications for textile coatings and adhesives as well as for general thickening in other industries.
