Selecting Tackifiers for Adhesives and Sealants
Tackifiers have been found to be especially useful in improving adhesion to hard-to-bond substrates such as low surface energy plastics and coated paper. They have also been found to promote high temperature adhesive performance in certain adhesive systems. Two examples that illustrate the additional benefits of tackifiers are:
Sylvatac RE | IMCD US
SYLVATAC RE 25 is recommended as an adhesive tackifier where the good wetting performance is required. Recommended uses include packaging, bookbinding, disposable, pressure sensitive and other adhesive applications as well as sealants, coatings and wax-based products.

- What is tackifier & plasticizer?
- Due to the molecular property of the resin the tackifier quicky travels to the substrate on the compound providing the much needed building tack. Plasticizer: These resins contribute as plasticizers during the compound of the rubber compound.
- What is the best tackifier resin?
- With more than 35 years of experience, and 30+ grades in AP Series we offer resins to a wide spectrum of Industries. POLYTONE® AP 121 and AP 121 H are our best offering as tackifier resin, these are Octyl Phenol based Novolak Resins which provide superior green tack along with added benefits of low colour and plasticizer properties.
- What are Tackifiers used for?
- In adhesive and sealant formulations, tackifiers are used to generate tack and improve specific adhesion (peel strength). They are incorporated into base polymers which mainly lack tackiness and pressure-sensitive properties but provide cohesion.
- Does tackifier increase Tg?
- Therefore, the tackifier addition raises the Tg of the final adhesive. Tackifiers operate opposite to plasticizers which lower the Tg of the adhesive formulation. The tackifying agent must be compatible with the base polymer. With hot-melt adhesives, consideration must also be given to the heat stability of the tackifier in the melt.
- 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.
- What happens if a polymer is compatible with a tackifier?
- IF a polymer and the tackifier are compatible a single Tg is observed but shifted to a higher temperature due to the higher Tg tackifier resin. In case of incompatibility, there will be two different Tgs, one polymeric phase and one resin phase.
