Ashland has developed Aroset 2100 PSA, a high-performance acrylic pressure sensitive adhesive (PSA).
The Dublin, Ohio-based company launched Aroset 2100 PSA at the Pressure Sensitive Tape Council Tape Summit 2018, held in Minneapolis, Minnesota May 7-11.
This coater-ready and self-crosslinking PSA enables pressure sensitive tape converters to manufacture tapes that combine high adhesion from polar surfaces with exceptional cohesion under a broad variety of challenging conditions. This adhesive was developed to provide specialty tape and label manufacturers with the capability to manufacture robust tapes for performance design spaces that were previously not available to solvent-based acrylic PSAs.
Key Aroset 2100 PSA attributes include:
- Class-leading room and high temperature shear, including greater than 500 hours of shear dwell time at 200°F (½” X ½” x 1 kg test configuration)
- Outstanding solvent resistance, including oil and fuel immersion of bonded surfaces
- Excellent adhesion to polar surfaces, including polyurethane
- High degree of optical clarity
- Good loop and probe tack
“Our group developed Aroset 2100 PSA in response to the tape market’s need for an adhesive that provides exceptional resistance to very high heat or challenging solvents without compromising very strong bonding capability to a broad range of polar plastics and metals,” said Lars Kilian, Ashland’s senior group leader for PSA product and applications development.
