Immersion varnish NQ for plastic and ceramic moulded parts
The product series of our dip coatings was developed under the name Dip Coating NQ. It is a Immersion varnish for substrates that are particularly difficult to colour, such as laser-sintered PLA mouldings or ceramic mouldings. These are produced in 3D printing and then dip coated. Because their surfaces are porous and non-absorbent at the same time, the dyeing results with other dipping lacquers were not satisfactory in terms of opacity and gloss.
The special feature of NQ dip coatings is the eponymous addition of nano quartz (NQ). These are nanoparticles with a special surface. During drying, they form a dense quartz film on the surface, closing the pores of the substrate or dyed part, creating a rich colouring and a clearly visible gloss.
Other possible applications are in the dyeing of similar substrates. Materials with a porous surface in the nanometer range can always be dyed with our NQ dipping lacquer. Thanks to nano quartz, no large quantities of lacquer seep into the substrate and a largely closed, coloured surface is formed.
Technical details of our immersion varnish:
The dipping inks and dip coatings of this series are all alcohol or solvent based. The volatile phase contains PM, DPM, ethyl acetate and butanol. The non-volatile, i.e. film-forming phase contains nano quartz, pigment and a resin as a binder. All colours are pigment formulations, so the light stability of the colours is very strong (wool scale 8). In addition, the film is water-resistant, but can be dissolved or diluted by organic solvents.
