Flat Lamination & Sandwich Construction

Flat lamination adhesives, e.g. for panel bonding and sandwich construction, need to have very long handling times .

Reactive hotmelts based on DYNACOLL® 7000 polyesterpolyols and DYNACOLL® AC acrylics provide very long open time combined with high initial creep resistance. As they are low viscosity, one component adhesives they can easily be applied at low melting temperatures without further mixing and be used as substitute for the previously used two component liquid polyurethanes.
