Making Nail Polish Less Sticky

Hey All,
I'm creating a water-based nail polish using Daitosol 5000 STY. This polymer makes the polish rather sticky and I'm not sure how to correct it. It does have a low Tg of 7 degrees C and I'm not sure if that has anything to do with it. Any suggestions?

    Resins that are ambient curing do tend to be softer when the Tg is lower, so you may want to take time to test a higher Tg ingredient and compare. The Tg might be too high if your coating is then brittle.

    However, a few things can cause a soft film. If you can, you will likely get better answers by posting your formula.

    With those styrene/acrylates I remember somewhere in the past that a little fatty alkyl amine added will raise the Tg, make film harder, less tack, more gloss and more water resistant. Cannot remember which one to use though. I'm thinking C16 or higher, maybe even an alkyl amidoamine.
