NATURE : Polyurethane binders and natural and synthetic fillers in water dispersion.
USE : STUCCO-RT is an easy buffable prebottoming compound for corrected-grain and split leathers. It allows to get excellent sealing and surface levelling before finishing, as it covers small defects, uniforms leather appearance and fullness and regularizes the absorption degree of subsequent finishes. STUCCO-RT forms a rubbery, elastic , matt film. The product has been formulated
so that it requires the addition of 15-20% of water before application on the leather. This operation allows the viscosity to be regulated to the desired degree. Anyremaining ROTAPASTE already diluted may give rise to surface layers, so careful stirring is needed before use.
The application of ROTAPASTE improves leather quality ,but even if the surface film obtained is excellent from a technical point of view, flexing endurance could be affected since more of it stays on the surface. We therefore recommend carrying out some specific preliminary tests before adoption.
EXAMPLE OF USE
STUCCO-RT is applied by rollercoater at a viscosity of 20” Ford Cup N. 6. Apply 60-80 g/sq.m. After application, dry plate at 80˚C, 100 atm and buff normally with 240 paper.
