At 40 \u00b1 2% solids, it provides a soft film with reported elongation at break of 1000-1500% and tensile strength of 20-30 MPa. The resin is described as forming fine, uniform foam and a level base surface, with water and toluene resistance. Foam formulation requires balancing filler level, foaming agent, expansion and application viscosity against the desired hand. For impregnation, a diluted dispersion can be applied through successive impregnation, squeezing and drying steps until the required result is obtained.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Soft hand and high extensibility<\/li>\n<li>Fine, uniform foaming profile<\/li>\n<li>Level synthetic leather base surface<\/li>\n<li>Flex, water and toluene 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\">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-1040<\/td>\n<\/tr>\n<tr>\n<td>Apparence<\/td>\n<td>Milky white dispersion<\/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>40 \u00b1 2%<\/td>\n<\/tr>\n<tr>\n<td>pH<\/td>\n<td>7.0-9.0<\/td>\n<\/tr>\n<tr>\n<td>100% modulus<\/td>\n<td>1.5-2.0 MPa<\/td>\n<\/tr>\n<tr>\n<td>Tensile strength at break<\/td>\n<td>20-30 MPa<\/td>\n<\/tr>\n<tr>\n<td>Elongation at break<\/td>\n<td>1000-1500%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.

Impregnate, squeeze and dry, repeating as needed after evaluating the substrate.<\/p>\n<ul>\n<li>Foaming and impregnation settings are development starting points, not a universal production recipe.<\/li>\n<li>Confirm resistance and mechanical performance using the final base construction and conditioning procedure.<\/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. Protect from freezing, high temperatures and direct sunlight. The stated storage period is 6-12 months; confirm the applicable shelf life for the supplied batch.<\/p>\n<h3>Request Technical Information or a Sample<\/h3>\n<p>Contact Longchang Chemical with the intended substrate, formulation system, process conditions and required performance.
