DAPRO® FX 510 is an effective NO-VOC coalescing agent for dispersions and dispersion paints. It reduces the minimum film formation temperature (MFT) and improves the scrub resistance of the paint layer.
DAPRO® FX 510 also has good hydrolytic stability properties and a very mild odour.
APPLICATION AND PROPERTIES
DAPRO® FX 510 can be applied to practically all usual dispersion systems, e.g.: polyacrylate homopolymers, - copolymers, polyvinyl acetate homopolymers, - copolymers, -terpolymers and polystyrene butadiene copolymers. DAPRO® FX 510 is applied to high PVC, medium PVC, as well as low PVC dispersion paints.e.g., gloss dispersion paints.
DAPRO® FX 510 is an auxiliary that when added to dispersions and dispersion paints, reduces the minimum film forming temperature and stimulates the coalescing of dispersion particles during the film
formation. As a result the mechanical properties of the paint layer are improved, in particular the scrub resistance. Therefore, it is usually the influence on the scrub resistance, which is taken as a criterion for the determination of the effectivity of the coalescing agent.
DAPRO® FX 510 is a non-foaming liquid with a good hydrolytic stability and a low odour. The product retains these properties both in the paint
and the paint layer.In some dispersions the freeze-thaw stability is
negatively influenced by coalescing agents; in these cases we recommend to combine DAPRO® FX 510 with NUOSPERSE® FN 1566 in the proportion of
approx. 10:3.DAPRO® FX 510 can also be added to the paint in
combination with e.g., anti-foaming agent DAPRO® GBR or with white spirit.
