It is supplied at 30 \u00b1 2% solids, with a pH of 7-9 and a viscosity range measured at 25 \u00b0C. The performance description emphasizes adhesion together with water, solvent and rubbing resistance. These characteristics should be evaluated in a complete formulation with the actual substrate and drying process. Specialist nail-coating development is also a listed application, but it requires separate composition, safety and regulatory assessment before any cosmetic use is approved.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Aliphatic polyurethane coating binder<\/li>\n<li>Adhesion-oriented profile<\/li>\n<li>Water, solvent and rubbing resistance for formulation evaluation<\/li>\n<\/ul>\n<h3>Technical Data<\/h3>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th scope=\"col\">\uc18d\uc131<\/th>\n<th scope=\"col\">\uac00\uce58<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-618<\/td>\n<\/tr>\n<tr>\n<td>\ubaa8\uc591<\/td>\n<td>Transparent liquid with a bluish cast<\/td>\n<\/tr>\n<tr>\n<td>Polymer type<\/td>\n<td>Anionic aliphatic polyurethane dispersion<\/td>\n<\/tr>\n<tr>\n<td>\uace0\uccb4 \ucf58\ud150\uce20<\/td>\n<td>30 \u00b1 2%<\/td>\n<\/tr>\n<tr>\n<td>pH<\/td>\n<td>7-9<\/td>\n<\/tr>\n<tr>\n<td>Viscosity at 25 \u00b0C<\/td>\n<td>50-200 mPa\u00b7s<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.
