Tack and cohesion are tailored to the application. Adhesion is of secondary importance. Many applications require a balance between tack and cohesion. Tack guarantees instant adhesion to the substrate, while cohesion is important for removal without residue. For many temporary applications, this is more important than a high specific adhesion that would manifest itself in a high adhesion level (peel resistance).
- Temporary/preliminary fixing
- Temporary surface protection
- Good bonding power on sensitive surfaces
- Removable without residue
- No change of colour or sheen
2. Permanent applications
Adhesion and cohesion are tailored to the application. Tack is of secondary importance. Adhesives in this area are primarily characterised by a balance between cohesion and adhesion tailored to the application. What is important is the durability of the bond. Tack, the bonding power at the first moment of contact, is of secondary importance.
- Permanent bond and safe fastening
- Good resistance to ageing/longevity
- Suitable for smooth and rough surfaces
3. Quick stick applications
Tack and adhesion are tailored to the application. Cohesion is of secondary importance. What is important for adhesives in this area is that they stick instantly and firmly. This is why tack and/or adhesion is required. As heavy loads are not usually to be supported and there is no unconditional need for removal without residue, cohesion often plays a secondary role.
- Rapid adhesion
- No heavy permanent loads
