We are doing printing on paper . To impart water resistance on printed paper we have tried different chemicals like SBR latex , Stryrene Acrylic Emulsion , Carnauba Wax emulsion etc . We are getting decent water resistance by using the above chemicals but we are facing problem of tack and the coated paper is become sticky due to these coatings . After winding the paper is getting blocked due to this. We are using gravure coating and the heating temp is around 80 deg celcius.

Any help would be greatly appreciated .
