The dispersion forms a smooth, glossy film and is suitable for evaluating printing pastes, paper treatments and coatings for electrical hardware. Its reported viscosity is 50-200 mPa\u00b7s, with a pH range of 7-9. Selection should consider the complete pigment, additive and substrate combination rather than the binder alone. Conduct compatibility and coated-substrate trials before setting production conditions, particularly where adhesion or resistance requirements are specified by the end customer.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Smooth film formation<\/li>\n<li>Glossy coating appearance<\/li>\n<li>Good film 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\">Propri\u00e9t\u00e9<\/th>\n<th scope=\"col\">Valeur<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-301<\/td>\n<\/tr>\n<tr>\n<td>Apparence<\/td>\n<td>Liquide blanc laiteux<\/td>\n<\/tr>\n<tr>\n<td>Polymer type<\/td>\n<td>Anionic aromatic polyurethane dispersion<\/td>\n<\/tr>\n<tr>\n<td>Teneur en solides<\/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\u00e9<\/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.

Establish application viscosity and drying conditions through trials on the actual substrate.<\/p>\n<ul>\n<li>Adhesion and film performance must be verified in the final formulation and on the intended substrate.<\/li>\n<li>No numerical tensile modulus is specified for this grade.<\/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>Emballage et stockage<\/h3>\n<p>50 kg or 120 kg plastic drums.<\/p>\n<p>Store at 5-30 \u00b0C in a cool, dry, ventilated place.
