Excellent combination of high tack and immediate adhesion
High coating weight for good bonding performance on rough or dusty surfaces
Suitable for long term applications
An outstanding adhesion level even to critical low surface energy materials such as PP and PE
Immediate functionality of the laminated bond due to excellent initial tack.
Suitability for most demanding applications such as heavy stress, high temperature of critical substrates
Light and age-resistant acrylic adhesive
Immediate usability right after assembly
High adhesion and very good bonding strength, even to low surface energy materials
Immediate functionality of the laminated bond due to excellent initial tack
Light- and aging-resistant acrylic adhesive for long-term applications
Very good plasticizer resistance
Good conformability for good adhesion even on rougher surfaces due to the PVC backing
