Within the last few decades, adhesive bonding technology has given engineers new opportunities to optimize and innovate their constructions and final products. The use of adhesives has become a real alternative to traditional joining techniques such as welding and riveting. Bonding of materials involves a sequence of operations, all of which need strict control and complete procedural documentation. Sika constantly tries to help customers improve their processes.
Sika has developed a series of pre-treatment products, which can be easy detected with UV light thanks to the addition of luminescent dyes. The treated surface will temporarily illuminate if exposed to UV light. This allows visual inspection to control whether an activator or primer has been applied or not.
