Its reported characteristics include a smooth film surface, gloss and good flex resistance. Listed uses cover waterborne inks, textile printing pastes, paper surface treatment and coatings for electrical hardware. The dispersion has a pH of 7-9 and a reported viscosity of 50-200 mPa\u00b7s. Formulators should evaluate the grade within the complete system, including pigment loading, additives and drying conditions, because the behavior of the finished coating depends on more than the resin specification.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Smooth, even film formation<\/li>\n<li>Glossy finish<\/li>\n<li>Film extensibility and flex resistance<\/li>\n<\/ul>\n<h3>Technical Data<\/h3>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th scope=\"col\">Eigendom<\/th>\n<th scope=\"col\">Waarde<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-302<\/td>\n<\/tr>\n<tr>\n<td>Uiterlijk<\/td>\n<td>Melkachtige witte vloeistof<\/td>\n<\/tr>\n<tr>\n<td>Polymer type<\/td>\n<td>Anionic aromatic polyurethane dispersion<\/td>\n<\/tr>\n<tr>\n<td>Vastestofgehalte<\/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>Viscositeit<\/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.

Confirm the required film appearance and flex performance with trials using the intended substrate and drying process.<\/p>\n<ul>\n<li>Flex resistance is a qualitative product characteristic; a specific test method and acceptance limit should be agreed for the application.<\/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>Verpakking en opslag<\/h3>\n<p>50 kg or 120 kg plastic drums.<\/p>\n<p>Store at 5-30 \u00b0C in a cool, dry, ventilated place.
