Bonding + Sealing

Dispensing systems for bonding and sealing applications

Perfection that lasts

Bonding represents a joining technology which is an established standard in many industries such as aerospace and automotive industry or railway vehicle manufacturing. Thanks to the development of new adhesives, it is possible to join together a large variety of materials such as glass, metal or plastics. The weight reduction of many products is one of the major reasons why this method is becoming so popular in various industries.

In the past decades, DOPAG was able to assume a leading position on the market due to constant optimization of its systems. These are not only capable of precise processing but also apply the adhesive to the material in just the right quantity. This saves a lot of otherwise wasted adhesive or sealant and also provides an optimal visual result. All DOPAG systems work according to DIN 2304, which ensures a professional realization of the joining technology “bonding”.
