    Anti-scratch paintTec Star antiscratch additive is designed for improving micro scratch resistance of water based resins.It is able to improve scratch resistance of a standard resin, making it to be classified MSR-A1, the best ranking of EN 16094:2012 - Laminate floor coverings- procedure A test method (change of gloss 10%).It is a water based additive, easy to add to liquid resins by mechanical mixing, not affecting the appearance of surfaces (colours, texture, shining, roughness) and not reacting with other chemical components of the resin (surfactants, hardeners, etc.).

    NanoAdditives for Ceramic EnamelWaAlOx Water-based Nanofluid for self-mending enamel:

    WaAlOx is a nanoparticle based product for water-based porcelain enamel for steel (in particular for low carbon steel) .

    Mixed with a glazed enamel enhances adhesion, providing a self-mending effect against brittle crack propagation.

    Field of application:

    Effects of the nanoparticles on amount and size of dendritesat the enamel-steel interface during the firing stage

    INCREMENT OF MECHANICAL PROPERTIES:

    mechanical resistance to bending and impact loads

    wear and scratch resistance

    low peeling effect on heavily deformed samples

    low time propagation of cracks on impacted samples

    heat exchanger corrosion control of the heating elements is a major topic

    complex geometries extraordinary adhesion and resistance to bending

    Nanocomposite anti-stick treatmentfor plastic mould

    SuperHydrophobic nanocomposite thin coating with anti-stick, anti-static and anti-corrosion properties with an extremely low-friction coefficient.

    The Plastic Mould Industry has the highest number of problems especially when there is a demand for highly complicated design, high gloss cosmetic finishings using various resin compounds etc.Some of the designs and methods of phased extraction also present unique problems in ensuring end products that can meet customers requirements.Depending on the additives and foreign materials mixed with the plastic resin, some compounds take longer to cool or their substrates are extremely sensitive and fragile.

    Super Hydrophobic thin coating dramatically reduces the friction coefficient of mould surfaces to produce high gloss finishes without using traditional mould release agents, with important increases in production output, reduced time spent on production and maintenance cycles, higher quality end products.

    Nanocomposite anti-stick treatment for plastic injection moulding

    Ultrathin hydrophobic spray-coatingwith high adhesion on the substrate giving easy release effect for plastic moulded parts. Works with all the main thermoplastic materials (PP, PE, PC, PMMA, ecc.).

    o no plastic sticking on the mould: o few discarded parts due to defects;o no change in mould geometry & perfect surface finishing (ultrathin);o user friendly;o could replace plastic release agents;o no need of surface cleaning procedures after moulding (ready for

    metallization, painting, labelling, etc.);o non-toxic or harmful.
