POLARTHANE 770 is a polyurethane resin which forms a medium dull and not sticky film.
POLARTHANE 770 is mainly used as intermediate coat before the leather printing and it can substitute the nitroemulsion in the finishing where a low solvent content is required: this feature makes this product especially suitable for automotive leather making.
POLARTHANE 770 is applied by spray after dilution 1:10 with water.
It is recommended to check regularly the adhesion on the coat after printing and/or milling and, if necessary, to add an adhesion promoter.
