It is positioned for leather finishing, PVC and PET film coatings, and waterborne ink or plastic coating systems. Its stated mechanical data pair a modulus of 6.0-8.0 MPa with elongation at break of at least 400%. The resin is intended to provide a smooth, transparent, glossy finish with resistance to UV exposure and yellowing. For selection, confirm adhesion, clarity, flexibility and ageing using the actual substrate preparation, formulation and drying process.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Balance of modulus and elongation<\/li>\n<li>Clear, smooth, high-gloss film<\/li>\n<li>UV and yellowing 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\">\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-6131<\/td>\n<\/tr>\n<tr>\n<td>\ubaa8\uc591<\/td>\n<td>\ud22c\uba85\ud55c \uc561\uccb4<\/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>Modulus<\/td>\n<td>6.0-8.0 MPa<\/td>\n<\/tr>\n<tr>\n<td>Viscosity at 30 \u00b0C<\/td>\n<td>\u2264 300 mPa\u00b7s<\/td>\n<\/tr>\n<tr>\n<td>Tensile strength<\/td>\n<td>\u2265 20 MPa<\/td>\n<\/tr>\n<tr>\n<td>Elongation at break<\/td>\n<td>\u2265 400%<\/td>\n<\/tr>\n<tr>\n<td>Water absorption, 24 h at 25 \u00b0C<\/td>\n<td>4-5%<\/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.
