HEC has good compatibility with acrylic binders, increasing paste thixotropy and preventing pigment settling without creating an excessively stiff film. In practice, pigment printing pastes containing HEC are more suitable for high-speed rotary screen printing, with significantly fewer broken lines and screen clogging, and sharp pattern edges free of serration.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a3f4944 elementor-widget elementor-widget-heading\" data-id=\"a3f4944\" data-element_type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">V.

It is recommended to slowly add HEC to room-temperature water under stirring, allowing complete wetting before adjusting pH (typically 10\u201311 to promote dissolution). Alternatively, a pH adjustment method can be used to accelerate dissolution.
