Its associative polyurethane chemistry is suited to screening in latex paints, adhesives, inks and flexible-substrate coatings. The product profile includes film formation, hiding, pigment wetting and reduced roller spatter, with thickening as the main function and leveling as a secondary contribution. Product information lists 40% and 50% solids options; confirm the selected supply specification before adjusting a formula. Rheology must be evaluated with the actual binder, pigment and surfactant package, because performance cannot be transferred unchanged between formulations.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Low-shear viscosity build<\/li>\n<li>Pseudoplastic rheology<\/li>\n<li>Supports pigment wetting and film formation<\/li>\n<li>Can reduce roller spatter in compatible systems<\/li>\n<\/ul>\n<h3>Technical Data<\/h3>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th scope=\"col\">\u8d22\u4ea7<\/th>\n<th scope=\"col\">\u4ef7\u503c<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae TH-255A<\/td>\n<\/tr>\n<tr>\n<td>\u5916\u89c2<\/td>\n<td>Colorless or pale-yellow transparent liquid<\/td>\n<\/tr>\n<tr>\n<td>Chemistry<\/td>\n<td>Nonionic associative polyurethane thickener<\/td>\n<\/tr>\n<tr>\n<td>Listed solids options<\/td>\n<td>40% or 50%; confirm the selected supply specification<\/td>\n<\/tr>\n<tr>\n<td>pH \u503c<\/td>\n<td>6-8<\/td>\n<\/tr>\n<tr>\n<td>\u7c98\u5ea6<\/td>\n<td>\u226430,000 mPa\u00b7s<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.
