Texicryl 13-302 Carboxylated acrylic copolymer Scott Bader Rheology Modifiers / Thickeners ADHESIVE >> Water-based Carboxylated acrylic copolymer used to thicken natural and synthetic latices TEXICRYL 13-302 is an aqueous emulsion of a carboxylated acrylic copolymer for use as a thickening agent for natural and synthetic latices. TEXICRYL 13-302 is particularly suitable for use as a thickener in the formulation of emulsion paints and for thickening various adhesive compounds. Alkaline solutions of TEXICRYL 13-302 have a much higher viscosity when diluted to a low solids content than of TEXICRYL 13-300. TEXICRYL 13-302 is therefore especially useful where an increase in the viscosity of the water-phase is an important factor in the thickening mechanism, e.g. thickening of emulsion paints. In high gloss emulsion paint formulations, TEXICRYL 13-302 has been found to assist in balancing the rheological properties of the paint, thereby improving applicational and flow properties. It can also be used in formulating chemical resistant, high P.V.C. sheen and semi-gloss emulsion paints. TEXICRYL 13-302 is particularly useful in thickening acrylic emulsions for use as print bonding adhesives in the production of non-woven fabrics. TEXICRYL 13-302 confers a highly pseudo-plastic rheology which minimises spreading of the print. To obtain optimum printing properties, however, it may be necessary to improve print transfer from the applicator roll by using a proportion with TEXICRYL 13-300. A 1:1 blend of the two emulsions, in most cases, gives an acceptable compromise of high thickening, low degree of print spreading and good print transfer. TEXICRYL 13-302 is generally less effective for thickening synthetic latices but is considerably more efficient as a thickener for natural rubber latex. Aqueous emulsion of a carboxylated acrylic copolymer. Used as a thickener for natural, synthetic latices and print bonding adhesives for non-woven fabrics. Gives a highly pseudo-plastic rheology which minimises spreading of the print and some applicational and flow properties. Used where an increase in the viscosity of the water-phase is an important factor in the thickening mechanism.
