Additives & Mediums
The decoration of ceramics requires inorganic powders which must be dispersed in a liquid and fixed to the item to be decorated. A wide range of organic binders, chemically very different between them, commonly called vehicles", are available for this very purpose.
The technique with which the decoration is to be applied (spray, silkscreen, decalcomania, ect.) and the working conditions (temperature, the distance between machines, the type of item the decoration it is to be applied to, etc.) and the specific characteristics of the vehicle (solubility, rheology, combustion temperature, ect) determine the choice of the vehicle which is most suited obtaining the desired results.
As for ceramic additives, they are chemical compositions of differing natures, which are used for decoration, as well as the correction and resolution of technical problems during production, or to modify certain characteristics of the materials and finished products.
Torrecid Group offers a wide choice of vehicles and additives:
MEDIUMS
Engraved Roller Printing Machine
Mediums are developed to achieve good anti-settling properties and colour stability, even with low viscosity inks and prolonged storage time. The mediums provide suitable discharge to achieve excellent definition and intensity. The special formulations allow density and viscosity to be maintained within required parameters, avoiding tonality changes.
Flat Screen Printing
Mediums with good fluidity and high definition during application. Good colour intensity is achieved due to the excellent dispersion properties. The special formulation provides optimum viscosity and consistency over the screen.
Third Firing Applications
Mediums are especially developed for decoration on third firing tiles. Drying times are adjusted for all kind of dryers. The pastes prepared have a rapid combustion, guaranteeing complete decomposition.
ADDITIVES
Glaze Additives
Additives have been developed to modify the rheology of glazes and aid silk-screen printing. As the additives are in liquid form, this allows them to mix easily into the glaze.
Spray - Dryers Additives
A range of additives have been developed to improve the green bending strength of pressed pieces and modify the rheology of all types of ceramic slips.
NonSlip Soft
NonSLIP SOFT is a product that, applied over green body tile or a glazed one gives, after the firing stage, a significant improvement in anti-slip resistance of the surface. This product provides soft finished surfaces with almost the same original tonality.
TINTOMETRIC SYSTEM
The range of mediums and additives has been designed to achieve all requirements in terms of suspension and rheology into the doser also in the final behavior of inks.
BINDERS AND FIXATIVES
Binders for Crush Frit Applications
Binders have been developed to achieve smooth surfaces following application with optimal drying time to fix grits. The special formulations allow good decomposition during the firing stage, without black core or pinholes.
Standard Fixatives
Fixatives that when applied form a perfectly smooth surface to fix particles and avoid loss of dust.
SPECIAL APPLICATIONS
Metallic Effects
Metallic concentrates specially developed to achieve products with added value.
Waterproofing Agents
Products formulated specifically to maintain the characteristics of floor tiles for a longer period of time, protecting them from soiling and making cleaning easier.
Glass Products
Mediums to decorate and improve the properties of glass pieces or vitreous mosaic with fast decomposition.
Glazing with Roller
These mediums achieve high density inks with excellent discharge resulting in applications with high thickness. The inks prepared remain stable over time without sedimentation problems.
Lapatto
Products with high wetting power to form a perfectly smooth surface free of lines from roller printing.
