  • Low color, low softening point C5/C9 tackifier resin
  • Low softening point promotes high tack, improved low temperature properties

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 permit the use of block copolymers with higher styrene content. It is stabilized by the addition of antioxidant.
