It is intended for formulations requiring a balance of medium film hardness, gloss, fullness and adhesion. The grade is listed for both intermediate and top finishing layers, as well as leather edge paints. Water, toluene and flex resistance are part of its qualitative performance profile. Compatible anionic resin blends may be evaluated to adjust the finished coating, but each blend should be checked for dispersion stability, application behavior and the required leather performance before production.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Glossy film with fullness<\/li>\n<li>Medium-hard coating profile<\/li>\n<li>Adhesion to leather substrates<\/li>\n<li>Water, toluene 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\">M\u00fclkiyet<\/th>\n<th scope=\"col\">De\u011fer<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-612<\/td>\n<\/tr>\n<tr>\n<td>G\u00f6r\u00fcn\u00fc\u015f<\/td>\n<td>Liquid dispersion<\/td>\n<\/tr>\n<tr>\n<td>Polymer type<\/td>\n<td>Anionic aliphatic polyurethane dispersion<\/td>\n<\/tr>\n<tr>\n<td>Film hardness<\/td>\n<td>Medium-hard<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.

During storage, keep the dispersion separate from curing agents; any deliberate crosslinking formulation requires controlled compatibility and pot-life trials.<\/p>\n<ul>\n<li>Confirm the current grade-specific solids and pH specifications with the supplied material before formulation scale-up.<\/li>\n<li>Leather adhesion, flex behavior and chemical resistance depend on the complete finishing system.<\/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>Paketleme ve Depolama<\/h3>\n<p>50 kg or 120 kg plastic drums.<\/p>\n<p>Store at 5-35 \u00b0C in a cool, dry, ventilated place. Protect from freezing and direct light and avoid direct contact with curing agents.
