Piccotac™ 7050 Hydrocarbon Resin
Case & carton sealing closings
Labels non food contact
Paints & coatings
Tape non food contact
Can be used with high styrene content block coploymers
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
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.
