Film-Forming Aids Polymers that make up emulsions or dispersions typically have glass transition temperatures above room temperature. To ensure good integration of emulsion particles into a uniform paint film, film-forming aids must be used to lower the minimum film-forming temperature (MFFT). Film-forming aids are a class of small-molecule organic compounds that eventually escape and volatilize f...

In many applications, acrylic adhesives do not require the addition of tackifying resins to improve pressure sensitivity, but in most cases, they are necessary: To increase initial tack and peel strength To improve adhesion to low surface energy materials Tackifying resins are commonly used in acrylic emulsion systems, such as paper labels and packaging tapes. They improve peel strength on difficu...
