Marapol PY is mainly used to print onto packaging containers of PE or PP and onto rigid PVC-types

Drying Physically fast drying,dries at 20°C within 20 to 30 min.(for overprintability),at 50°C in a tunnel dryer within 30-60sec.The times mentioned vary according to thickness of the ink film,with or without addition of hardener and type of hardener,drying conditions and auxiliaries used.Please note that the drying speed slows down i shades are overprinted and a hardener has been used. Stress resistance After proper and thorough drying,the ink film exhibits outstanding adhesion as well as rub and scratch resistance and is resistant to oils,greases,diluted acids and bases,and alcohol.Application:         Marapol PY is mainly used to print onto packaging containers of PE or PP and onto rigid PVC-types.When printing onto PE and PP,the surface of the substrate must be pre-treated in the usual way,either by flaming or by Corona discharge.According to our experience,the PY adheres on polyolefines with a minimum surface tension of 42-48mN/m.PY can also be processed with a spray gun,but preliminary trials are necessary for this process.We recommend to filter the thinned press-ready ink(25μm screen)before processing it,as otherwise there could be bubbles in the ink film.
