The resin is reported to form a smooth, glossy, flexible film with adhesion to PVC and PET substrates. Its tensile strength is 20-30 MPa, with elongation at break of at least 400% and water absorption of 3-5% after 24 hours at 25 \u00b0C. The viscosity limit is reported at 30 \u00b0C and should not be compared directly with values measured at other temperatures. Where increased water resistance is required, a compatible crosslinker can be evaluated within the complete formulation.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Smooth, glossy film<\/li>\n<li>Flexible coating profile<\/li>\n<li>Adhesion to PVC and PET for formulation evaluation<\/li>\n<li>Water-resistance-oriented binder<\/li>\n<\/ul>\n<h3>Technical Data<\/h3>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th scope=\"col\">\uc18d\uc131<\/th>\n<th scope=\"col\">\uac00\uce58<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-6128<\/td>\n<\/tr>\n<tr>\n<td>\ubaa8\uc591<\/td>\n<td>Translucent liquid<\/td>\n<\/tr>\n<tr>\n<td>Polymer type<\/td>\n<td>Anionic waterborne polyurethane dispersion<\/td>\n<\/tr>\n<tr>\n<td>\uace0\uccb4 \ucf58\ud150\uce20<\/td>\n<td>35 \u00b1 1%<\/td>\n<\/tr>\n<tr>\n<td>pH<\/td>\n<td>6.0-8.0<\/td>\n<\/tr>\n<tr>\n<td>Viscosity at 30 \u00b0C<\/td>\n<td>\u2264150 mPa\u00b7s<\/td>\n<\/tr>\n<tr>\n<td>Tensile strength<\/td>\n<td>20-30 MPa<\/td>\n<\/tr>\n<tr>\n<td>Elongation at break<\/td>\n<td>\u2265400%<\/td>\n<\/tr>\n<tr>\n<td>Water absorption, 24 h at 25 \u00b0C<\/td>\n<td>3-5%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.

Waterborne use does not by itself establish solvent-free status or a hazard classification.
