Hi,
Which polymers have strong adhesion (stickiness, tackiness) properties? What should be the ratio between the polymer and the plasticizer in the film that is placed on the skin?
Well, adhesion promoters are designed for that. Just search for those specific to skin. My Regards
Dear Modestas Zilius, polycyanoacrylates and polyvinylacetates, but more details are needed. My Regards
I use polyvinyl alcohol (PVA) as polymer and propylene glycol (PG) as plasticizer. The ratio of PVA and PG is 1:5. The amount of polymer is from 0.4 to 1.0 g and the amount of plasticizer is from 2.0 to 5.0 g.
If tackiness is important PVAc (polyvinylacetate) is much better than PVAl, and even you may not need to add a plasticizer. My Regards
Thanks for the advice, but the components of my film composition are PVA and PG. The only question is what else can be added to the composition to increase the stickiness (tackiness) of the films. It is important that such films adhere to human skin. My Regards
