What is a tackifying agent?

Tackifiers are chemical compounds used in formulating adhesives to increase the tack, the stickiness of the surface of the adhesive. ... Tackifiers tend to have low molecular weight, and glass transition and softening temperature above room temperature, providing them with suitable viscoelastic properties.

What is tackifying resin?

Tackifiers are low-molecular weight compounds (oligomers) that are added to adhesive formulations to improve tack and peel adhesion. Their glass transition temperature (T_g) is typically higher than that of the base polymer but their molecular weight is much lower. ... Hydrocarbon resins are the most popular tackifiers.
