Select Tackifiers for Adhesives and Sealants

This guide will endeavor to direct the formulator through the process of selecting a tackifier for a specific adhesive system and end-use requirement. Tackifiers are important low molecular weight constituents in hot melt and pressure sensitive adhesives in terms of their effect on both cost and performance properties. This guide directs about the various classes of tackifiers, their functioning, applications, benefits and limitations of tackifiers.

Tackifiers for Adhesives

Tackifiers are important low molecular weight constituents in hot melt and pressure sensitive adhesives in terms of their effect on both cost and performance properties. In practice, formulators use tackifiers to make the correct balance between adhesion and cohesion which is dependent on the end-use application. Tackifiers do this by lowering the modulus and increasing the glass transition temperature of the final adhesive.

This guide will endeavor to direct the formulator through the process of selecting a tackifier for a specific adhesive system and end-use requirement. Tackifiers must be considered with regard to the end-properties that the formulator is trying to achieve, the type of processing that the adhesive will be subject to, and the chemical nature of the base polymer. There are many different types of tackifiers and choosing the optimum tackifier for a specific formulation can be a very challenging task.
