  • Are Tackifiers compatible with a base polymer?
  • In order to effectively provide these modifications, tackifiers must be compatible or partially compatible with the base polymer. The first and most important criterion in the selection process is the compatibility between the tackifier and the base polymer in the adhesive formulation.
  • What are Tackifiers & plasticizers in PSAs?
  • Source: Extance, A., “Using Tackifiers and Plasticizers in PSAs”, SpecialChem, February 9, 2009. Plasticizers are organic liquids or solids that are incorporated by melt processing or diffusion into a compatible polymer to reduce interaction between molecules and improve molecular mobility.
  • What is a tackifier used for?
  • Tackifiers tend to have relatively low molecular weight with glass transition and softening temperatures that are above room temperature. They are most often used in an adhesive formulation containing a base polymer that has a Tg below room temperature. Therefore, the tackifier addition raises the Tg of the final adhesive.
  • What are neoprene Tackifiers?
  • Neoprene contact adhesives, in which phenolic resins are used to improve processing and heat resistance. In addition to modify tack, adhesion, and cohesion, tackifiers will affect other properties. These may be advantageous or disadvantageous to the formulator.
  • Why do formulators use Tackifiers?
  • They are used to increase the tack or "stickiness" of the adhesive. In practice, formulators use tackifiers to make the correct balance between adhesion and cohesion which is dependent on the end-use application. They do this by lowering the modulus and increasing the glass transition temperature of the final adhesive.
  • Which tackifier should be used in a non-styrene phase?
  • The aliphatic C5 resins, which are more compatible in the non-styrene phase, therefore are more likely to be used. However, in certain applications it may be desirable to increase or decrease the Tg of the end-phase and for this an end-phase compatible tackifier such as aromatic hydrocarbon resin may be used.
