FlexLINK 640 R+ is a high performance adhesive tape made of a syntactic white acrylate foam core and adhesive layer. It is suitable for bonding difficult surfaces like varnish or plastics to rough surfaces. The adhesive provides good tack at low temperatures and on delicate surfaces. Tensions in the bond are balanced by the rheological properties of the foam core, and bonding stability increases over time. In addition to bonding, it provides cushioning and insulation.

FlexLINK 640 R+ is a high performance adhesive tape system with a core of a syntactic,
white acrylate foam.
It is perfectly suitable for gluing difficult surfaces like varnish or plastics onto rough and uneven surfaces.
This specially modified adhesive provides a good immediate tack and handling safety at low temperatures
and on delicate surfaces. Tensions arising within the glue link are balanced by the rheologic
characteristics of the syntactic foam. The bonding stability increases with proceding age of the link. In
addition to its linking task, the gluing provides good cushion and insolation properties.
