Eastman Piccotac™ 7050 Hydrocarbon Resin
Categories: Polymer

Material Notes: Product Description: Piccotac™ 7050 hydrocarbon resin is a low softening point, aromatic modified C5 resin. This light colored resin is designed for use in adhesive systems based on either aliphatic or aromatic elastomers. Due to its unique properties, Piccotac™ 7050 can be used at a higher level than typical hydrocarbon tackifiers and its high level of aromatic modification can pemit the use of block coploymers with higher styrene content. It is stabilized by the addition of 0.10% antioxidant.

Application/Uses:

  • Building and Construction
  • Footwear and Leather
  • Hot Melt Adhesives
  • Laminating
  • Nonwovens
  • Packaging
  • Pressure sensitive adhesives
  • Solventborne Adhesives
  • Tapes and Labels
Key Attributes:
  • Can be used with high styrene content block copolymers
  • Compatible tackifier for many PSA systems
  • High aromatic modification to provide processability and wet out
  • Low Color, Low softening point C5/C9 tackifier resin
  • Lower softening point to provide increased tack and low temperature performance
