Low Viscosity Resins

Hydra Technology produces dendritic vinyl polymers which are a class of polymers between linear polymers and dendrimers. They are characterised by a densely branched backbone and large number of reactive groups. Their globular structures have excellent flow and processing properties, even at high molecular weight.

The unique architecture allows many end groups to be designed into the polymer. This provides highly interactive materials which exhibit strong surface interactions, which are desirable in applications that require good adhesion, such as coatings and adhesives. Low solution viscosities allow high solids, low VOC formulations to be achieved.

Hydra resins can be used to improve efficiency or meet environmental targets for a range of coatings applications. 

• Low solution viscosity at high solids allowing low VOC formulations
• High molecular weight
• Good adhesion
• Good scratch resistance
• Range of chemistries, e.g. acrylics, styrenics or curing systems
   

Hydra polymers are considerably less viscous than their linear counterparts at the same molecular weight. This can be seen below where Hydra methacrylate and polyol-based resins are compared to their linear analogues.

The Hydra Technology allows for extremely high molecular weight but low viscosity materials to be prepared. Resins can be produced with high Mw and still be free flowing.
 

In addition to their excellent flow behaviour, Hydra resins tend to exhibit better scratch resistance than their linear counterparts and can be designed to offer good adhesion.
