The document discusses nanocomposite materials and their applications in paints and functional coatings. It describes how Tec Star produces nanoparticles that provide new properties when used as nanofillers, such as increasing scratch resistance, UV resistance, and corrosion protection for paints. The nanoparticles can also provide benefits for functional coatings, ceramic enamels, and anti-stick treatments for plastic molds. Case studies demonstrate improvements in properties like wear resistance and corrosion resistance.

Anti-scratch paint
TEC STAR produces nanoparticles that, used as nanofillers for paints and inks, provide new
properties to polymer coatings, solving many problems related to the varnish industry:
. increasing scratch resistance and surface hardness
. improvement of UV light resistance
. increasing corrosion protection
. improvement of antiseptic effect
. increasing thermal insulation
. increasing electrical conductivity.
Paints treated:
. Polyurethanic solvent based
. Polyurethanic water based
. UV

Anti-scratch paint
Tec 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.).

Functional Coatings
Development of additives for the galvanic and polymer
coating, to provide the traditional coatings (nickel, zinc,
cataphoretic paints, etc..) with high mechanical properties
(low friction coefficient and wear rate), corrosion
resistance and hydrophilic/hydrophobic surface properties.

NanoAdditives for Ceramic Enamel
WaAlOx – 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 dendrites
at 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 treatment
for 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.
