Hydrogenated C5, Aliphatic Resins

Hydrogenation is a process used after a resin is polymerized to decrease its color and improve its stability towards heat, oxygen, and ultraviolet light. While the hydrogenation process will increase the cost of a resin it will also improve its properties. In some critical applications, only the highest stability and lowest color of tackifier resin will suffice. Any base tackifier resin can by hydrogenated and Eastman supplies hydrogenated tackifiers based on rosin resins, C5 hydrocarbon resins, and C9 hydrocarbon resins.

The Eastotac™ brand of hydrogenated aliphatic tackifier resins offers a line of products with a wide range of softening points, levels of hydrogenation, and color. Eastotac™ hydrogenated aliphatic tackifiers are produced in Longview, Texas and Nanjing, China. The low color, excellent thermal stability, and aliphatic chemical properties of Eastotac™ aliphatic tackifiers make them most useful in SIS-based hot melt nonwoven assembly adhesives, polyethylene based packaging adhesives, EVA-based packaging adhesives using EVA of less than 28% vinyl acetate, hot melts based on amorphous polyolefin, hot melt road marking compounds, and petroleum wax compounds.
