Its listed uses include waterborne paper inks, wood finishes, metal coatings and other industrial coating formulations. It is characterized by adhesion to different substrates and qualitative resistance to water, solvents and rubbing. The grade can also be evaluated for specialist nail-coating formulation work, but that application listing does not establish cosmetic regulatory suitability or human-use safety. Confirm the current grade-specific specifications, intended end-use requirements, formulation compatibility and film performance before selecting the resin for production.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Adhesion-oriented coating binder<\/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\">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-616<\/td>\n<\/tr>\n<tr>\n<td>Aspetto<\/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<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.

For any cosmetic end use, obtain the required composition, safety and regulatory documentation before formulation approval.<\/p>\n<ul>\n<li>Confirm the current grade-specific solids, pH, viscosity, film hardness and shelf life with the supplied material before use.<\/li>\n<li>A listed nail-coating application is not a cosmetic compliance or safety certification.<\/li>\n<\/ul>\n<p>Check binder compatibility, substrate preparation, application conditions and final coating or bond performance in your own formulation. Waterborne use does not by itself establish solvent-free status or a hazard classification. Consult the current safety data sheet and use appropriate industrial handling controls.<\/p>\n<h3>Imballaggio e stoccaggio<\/h3>\n<p>50 kg or 120 kg plastic drums.<\/p>\n<p>Store at 5-30 \u00b0C in a cool, dry, ventilated place.
