Designed Polymers for the Construction Industry
Edge Bonding & Profile Wrapping
Hot melt adhesives are used for bonding various kinds of edges or plastic films to fiberboards providing high productivity due to physical setting.
DYNACOLL® 7000 based reactive hot melts have to be used for furniture, e.g. for kitchens and bathrooms where high temperature resistance as well as water vapor resistance is requested.
DYNACOLL® S copolyester based reactive hot melts are primarily used for laminating PVC films on window frames made of PVC or aluminum for decorative purposes. Green strength has to be very high in order to obtain high productivity. Outdoor applications, in particular, have very high temperature and weather resistance requirements.
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.
Silicone Consumer Sealants
POLYVEST® is used as a hydrophobic wetting agent in one-pack sealers for sanitary and DIY applications. The formulations are commonly chalk filled and based on silicone rubbers.
