Acrylate levelling agents have little effect on the surface energy of coatings, while silicone or fluorobased additives reduce it. However, a high surface energy is desirable in primers to increase intercoat adhesion. A new branched polyacrylate levelling additive designed to increase surface energy has shown positive results in waterborne automotive primer surfacers.

Dispersing additives with a hyperbranched core/ shell structure have been developed with encapsulated aminic pigment-affinitive groups. These can be used in solvent-borne and solvent-free coating systems. They provide highly effective stabilisation of various types of pigment while avoiding any undesirable interactions with reactive coating systems.
