Your Challenge

Price variations of Gum Rosin Esters have a strong impact on the cost of your Adhesive Formulation. However, you cannot afford to supply formulations with such fluctuating prices. As a Hotmelt Adhesive Formulator, you are looking for a reliable solution that would help you improve the performance of your formulation.

Your Solution

This Terpene Phenolic Resin as naturally-based tackifier is the perfect solution for formulators who want to improve the adhesion of their formulation on difficult substrates.

It has an excellent compatibility with a wide range of elastomers and can also help you stabilize the cost of your formulation thanks to steady and reliable prices.

Adhesion on difficult substrates & compatibility with various elastomers

This Terpene Phenolic Resin shows an excellent adhesion on difficult substrates, and is compatible with various elastomers.

The table below compares the MMAP value and molecular weight of the Terpene Phenolic Resin vs benchmark Rosin Esters.

	Terpene Phenolic Resin	Benchmark Rosin Ester	Advantages of Terpene Phenolic Resin
MMAP (aliphatic / aromatic character of the resin)	+25	+3	Improved compatibility in PSA Hotmelt Formulations
Mn (molecular weight)	500	1000	Better adhesion on difficult substrates

Table 1: Properties of Tackifier Resins

It clearly shows that the MMAP value is higher for this Terpene Phenolic Resin, which means that it is more aliphatic than benchmark Rosin Ester, for an improved compatibility in Hotmelt Adhesives Formulations.

Moreover, the Terpene Phenolic Resin also has a lower molecular weight, for a better adhesion on difficul

The table below illustrates the excellent compatibility of the Terpene Phenolic Resin with a wide range of elastomers:

This material can be suitable for almost all your Hotmelt Adhesive formulations, whatever the elastomer, and help you to reduce sourcing problems.

No residual acidity

Last but not least, this Terpene Phenolic Resin is a neutral resin, which shows no residual acidity compared to rosin esters:
