The resin forms a soft, transparent protective film and is described as offering leveling, water resistance and yellowing resistance. Its peelability must be developed for the actual substrate, surface condition and protection duration. A suggested process is to allow the applied coating to stand for 10 minutes before drying at 60-80 \u00b0C, with a dry-film thickness above 50 \u00b5m to support peeling. These conditions are trial starting points; verify film continuity, removal force, surface compatibility and any residue after the intended exposure period.<\/p>\n<h3>Grade Characteristics<\/h3>\n<ul>\n<li>Soft, transparent protective film<\/li>\n<li>Peelable coating profile<\/li>\n<li>Leveling and application characteristics<\/li>\n<li>Water and yellowing resistance for evaluation<\/li>\n<\/ul>\n<h3>Technical Data<\/h3>\n<table style=\"width:100%;border-collapse:collapse\">\n<thead>\n<tr>\n<th scope=\"col\">Propriet\u00e0<\/th>\n<th scope=\"col\">Valore<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Brand and grade<\/td>\n<td>CHLUMICRYL\u00ae WPU-8083<\/td>\n<\/tr>\n<tr>\n<td>Aspetto<\/td>\n<td>Slightly whitish, clear liquid<\/td>\n<\/tr>\n<tr>\n<td>Product type<\/td>\n<td>Peelable waterborne polyurethane protective resin<\/td>\n<\/tr>\n<tr>\n<td>Contenuto di solidi<\/td>\n<td>35 \u00b1 2%<\/td>\n<\/tr>\n<tr>\n<td>pH<\/td>\n<td>7-9<\/td>\n<\/tr>\n<tr>\n<td>Viscosit\u00e0<\/td>\n<td>200-1000 mPa\u00b7s<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These values are technical selection data, not a batch-specific certificate of analysis.

Confirm substrate heat tolerance, film continuity and removal behavior before production.<\/p>\n<ul>\n<li>Peel force and residue behavior depend on substrate, film thickness, exposure duration and conditions; verify each intended use.<\/li>\n<li>Temporary protection does not establish permanent outdoor durability or compatibility with every painted surface.<\/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>Imballaggio e stoccaggio<\/h3>\n<p>50 kg or 120 kg plastic drums.<\/p>\n<p>Store at 5-30 \u00b0C in a cool, dry, ventilated place. Protect from freezing and direct light.
