The anionic aliphatic dispersion has a stated 100% modulus of 0.8-1.2 MPa and elongation at break of at least 800%. It is suitable for screening as the film-forming binder in printing pastes, waterborne leather finishes and treatments for elastic substrates. Its pH of 6-8 and viscosity of 100-1000 mPa\u00b7s should be considered when selecting pigments, additives and application rheology. Evaluate the complete formulation for adhesion, feel and appearance after drying.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Soft hand feel<\/li>\n<li>Smooth, full-bodied film<\/li>\n<li>High 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\">Eigentum<\/th>\n<th scope=\"col\">Wert<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-1158<\/td>\n<\/tr>\n<tr>\n<td>Erscheinungsbild<\/td>\n<td>Milchig-wei\u00dfe Fl\u00fcssigkeit<\/td>\n<\/tr>\n<tr>\n<td>Gehalt an festen Stoffen<\/td>\n<td>48 \u00b1 1%<\/td>\n<\/tr>\n<tr>\n<td>pH-Wert<\/td>\n<td>6-8<\/td>\n<\/tr>\n<tr>\n<td>Viskosit\u00e4t<\/td>\n<td>100-1000 mPa\u00b7s<\/td>\n<\/tr>\n<tr>\n<td>100% modulus<\/td>\n<td>0.8-1.2 MPa<\/td>\n<\/tr>\n<tr>\n<td>Elongation at break<\/td>\n<td>\u2265 800%<\/td>\n<\/tr>\n<tr>\n<td>Tensile strength at break<\/td>\n<td>\u2265 5 MPa<\/td>\n<\/tr>\n<tr>\n<td>Ionic type<\/td>\n<td>Anionic<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.
