Tackifier resins are sold either as 100% non-volatile forms or as Resin Dispersions.
There are hundreds of tackifier resins available from many different suppliers but nearly all are based on three basic raw material feed streams. This provides a simple and logical way to classify these products. A brief description of each tackifier family is shown below. Click on the links below the description for more detailed information and for a listing of products Eastman offers in each category.
- Rosin Resins are derived from either aged tree stumps (wood rosin), sap (gum rosin), or by-products of the paper making process (tall oil rosin). They impart excellent, aggressive adhesion to almost all polymer types, including natural rubber, EVA, SBR, SIS, SBS and acrylics.
- Hydrocarbon Resins are made from petroleum based feedstocks either aliphatic (C5), aromatic (C9), DCPD (dicyclopentadiene), or mixtures of these.
- Terpene Resins are derived from terpene feedstocks either from wood sources or from citrus fruit. They impart excellent, aggressive adhesion to almost all polymer types, including, natural rubber, EVA, APO, PE, SBR, SIS, SBS, and acrylics. Due to their very broad compatibility, they are sometimes called “universal tackifiers”. Terpene resin use, however, is somewhat restricted due to their limited supply and high cost.
