Its high solids level, pH of 7-9 and viscosity range of 100-1000 mPa\u00b7s provide a defined liquid-property starting point for formulation work. The aliphatic polyurethane film is intended to combine gloss, smoothness, strength and extensibility. Recommended screening areas include printing pastes, waterborne leather treatments and elastic substrate coatings. Formulate application rheology separately for the chosen process, then assess adhesion, feel, appearance and extension on the finished substrate rather than extrapolating from free-film values alone.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>High-solids polyurethane dispersion<\/li>\n<li>Level film with gloss<\/li>\n<li>Film strength and extensibility<\/li>\n<\/ul>\n<h3>Technical Data<\/h3>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th scope=\"col\">Eigentum<\/th>\n<th scope=\"col\">Wert<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-2155<\/td>\n<\/tr>\n<tr>\n<td>Erscheinungsbild<\/td>\n<td>Milchig-wei\u00dfe Fl\u00fcssigkeit<\/td>\n<\/tr>\n<tr>\n<td>Gehalt an festen Stoffen<\/td>\n<td>55 \u00b1 2%<\/td>\n<\/tr>\n<tr>\n<td>pH-Wert<\/td>\n<td>7-9<\/td>\n<\/tr>\n<tr>\n<td>Viskosit\u00e4t<\/td>\n<td>100-1000 mPa\u00b7s<\/td>\n<\/tr>\n<tr>\n<td>100% modulus<\/td>\n<td>1.5-2.0 MPa<\/td>\n<\/tr>\n<tr>\n<td>Elongation at break<\/td>\n<td>\u2265 1000%<\/td>\n<\/tr>\n<tr>\n<td>Ionic type<\/td>\n<td>Anionic<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.
