Scott Bader Introduces TEXICRYL® 13-319, a HASE Rheology Modifier for Coatings

Published on 2016-06-06. Author : SpecialChem

TEXICRYL® 13-319 is the latest HASE polymer in Scott Bader’s growing range of rheology modifiers. The pure acrylic polymer is activated by neutralizing to pH 8-9 and provides a dramatic pseudoplastic rheological effect to the water-based system.

TEXICRYL® 13-319 is supplied at 30% solids content, the typical addition level would be less than 0.5% to prevent settling and sagging whilst maintaining levelling properties. These properties are achieved through polymer modification; incorporation of hydrophobic groups to associate with particles at low shear, dissociate at high shear and then recover in a controlled manner.

TEXICRYL® 13-319 is compatible with a broad range of coating and adhesives components and provides excellent pigment suspension. Although TEXICRYL® 13-319 can be used alone in very high viscosity formulations, benefits are found when used in combination with other Scott Bader rheology modifiers. TEXICRYL® 13-317, another pure acrylic polymer is designed to influence the higher shear rate viscosity of the system, therefore reduce spattering on application. The formulator can therefore achieve a no-compromise balance of these properties through fine tuning the addition levels of TEXICRYL® 13-317 & TEXICRYL® 13-319.
