Abstract: The present invention relates to aqueous polyurethane dispersions prepared with no catalyst or very low loading of organic catalyst that can be used as cold sealable adhesives, are surfactant and solvent free and have low VOC emissions, are environmentally friendly, and provide for homogeneous and aging-resistant adhesives that can be used for cosmetic, pharmaceutical and food packaging applications. Also encompassed are processes for their production, compositions containing them and their use as adhesives.

Abstract: An aqueous adhesive dispersion containing 25 to 70 wt % acrylate block copolymers and/or styrene block copolymers that have a molecular weight of more than 15,000 g/mol and at least two different glass transition temperatures, one glass temperature (Tg) being above 50° C., the other glass transition temperature below +10° C., as well as additionally further additives, the dispersion containing less than 0.5 wt % organic solvent.

Abstract: The invention relates to a low-viscosity hotmelt adhesive containing A) at least one hydrocarbon resin solid at 20° C. with a softening temperature of 70 to 140° C., B) at least one oil with an average molecular weight of >500 and preferably C) a styrene block copolymer. The new hotmelt adhesive is distinguished by a melt viscosity of essentially only 500 to 3200 mPas at 150° C. for a softening temperature of 60 to 115° C. It is preferably used in the field of hygiene for bonding films, nonwovens and/or shaped articles of cellulose derivatives, being distinguished by particular resistance to dermatologically compatible coatings.
