The anionic aliphatic polyurethane dispersion is suited to paper finishing and leather surface treatment, with emphasis on black appearance and a fine, velvety feel. Its pH range is 7-9, and application rheology should be adjusted to the selected coating method. Assess the complete formulation on the intended substrate, because pigments, other binders and coat weight influence touch and appearance. Where the process includes heating, validate exposure temperature and duration on the actual coated article.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Low-gloss surface finish<\/li>\n<li>Deep black appearance in suitable formulations<\/li>\n<li>Fine, soft, velvety touch<\/li>\n<\/ul>\n<h3>Technical Data<\/h3>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th scope=\"col\">Propriet\u00e0<\/th>\n<th scope=\"col\">Valore<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-415<\/td>\n<\/tr>\n<tr>\n<td>Aspetto<\/td>\n<td>White dispersion<\/td>\n<\/tr>\n<tr>\n<td>Contenuto di solidi<\/td>\n<td>35 \u00b1 2%<\/td>\n<\/tr>\n<tr>\n<td>pH<\/td>\n<td>7-9<\/td>\n<\/tr>\n<tr>\n<td>Viscosit\u00e0<\/td>\n<td>1000-2000 mPa\u00b7s<\/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.
