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.
Key technical requirements for PSAs 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 choice.
Visit the Tapes and Labels Applications section of the Tackifier Center for specific reference information.
