HANSA® ADD 1045 | Overvarnishable levelling additive with a high slip and anti-crater effect

HANSA® ADD 1045 is a universally applicable, highly efficient levelling additive for aqueous and solvent-based wood and industrial coatings. HANSA® ADD 1045 stands out particularly as anti-crater additive which can be easily overvarnished and which has a clearly lower foaming tendency.

Due to its special chemical composition and its very good compatibility HANSA® ADD 1045 is excellently suited for transparent high gloss systems which are not only imparted with enormous slip properties but additionally with an improved scratch resistance.

Besides the excellent slip HANSA® ADD 1045 simultaneously ensures very good overvarnishing properties. This product neither affects the gloss of coating systems nor does it lead to any dulling.


Very low foaming tendency

The disadvantage of surface-active additives is that their strong foam stabilisation often leads to an insufficient incorporation into a coating at high shear forces.

In comparison to common surface-active products, HANSA® ADD 1045 clearly foams less and offers thus the advantage of a smooth and effective incorporation during the manufacturing process.




Overview of advantages and properties
