Pressure sensitive adhesives (PSA) are the most useful of all adhesive types due to their ease of application and immediate bonding characteristics.
Hot melts, solvent-based, and water-based technologies are all used for PSA products. Newer technologies include radiation curable, hot melt PSA for improved cohesion especially at high temperatures.
A wide variety of applications include: |
|
• |
Specialty tapes |
|
• |
Repositionable tapes |
|
• |
Packaging tapes |
|
• |
Hook and loop tapes |
|
• |
Permanent labels |
|
• |
General purpose labels |
|
• |
Peelable/repositionable labels |
|
• |
Direct food contact applications |
|
• |
High-tack adhesives, suitable for many difficult filmic substrates, including those where the clear "no label" look is desired |
|
• |
Low temperature applications | |
Key technical requirements in the pressure sensitive adhesive industry are:
- Precise viscosity control for exact adhesive coating weights.
- Smooth, fast machinability.
- Excellent adhesion/cohesion balance.
- Aging stability.
- Fast, clean die-cutting for labels.
- Bonding to a wide variety of substrates.
- Good low temperature performance.
Tacolyn resin dispersions provide excellent performance in water-based acrylic PSA for a variety of label applications and natural rubber latex tapes.
Eastotac, Regalite and Piccotac resins are ideally suited for styrenic block copolymer-based PSA. For end-block reinforcing adhesives, Kristalex and Plastolyn hydrocarbon resins are the right brand choice. | |
