Controlled abrasive
The projection of high-speed metal abrasives removes rust, mill scale, oxidation and surface contaminants.
Sandblasting.
Sandblasting is a fundamental treatment for preparing metal surfaces before coating.
Through the controlled projection of high-speed metal abrasives, it removes rust, mill scale, oxidation and surface contaminants, producing a clean and uniform surface.
Correct preparation of the substrate is decisive for paint adhesion, corrosion resistance and the durability of the protective cycle.
What is sandblasting
Sandblasting is a mechanical process used to prepare metal surfaces before coating or other surface treatments.
For this reason it is often the first step in high-performance anti-corrosion cycles.
remove rust and oxidation
eliminate mill scale and impurities
remove machining residues
even out the surface
create the correct roughness profile to promote paint adhesion
prepare the substrate for subsequent protective cycles
From metal to coating cycle
The preparation that determines the durability of the treatment.
Uniform substrate
The surface is brought to a clean and homogeneous condition, ready for subsequent treatments.
Roughness profile
The correct surface profile promotes paint anchoring and reduces the risk of detachment.
Protective cycle
The preparation maximises adhesion, corrosion resistance and the durability of the part over time.
The advantages
Better paint adhesion
Greater corrosion resistance
Elimination of surface contaminants
Increased durability of the coating cycle
Reduced risk of flaking and detachment
Optimal preparation for e-coating, powder coating and liquid coating
Blasting grades
Preparation according to ISO 8501.
ISO 8501
Zoccarato Industrial Coatings carries out treatments compliant with the ISO 8501 standard, the international reference for the preparation of steel surfaces.
Blasting grade
The grade is chosen based on the operating conditions of the component and the performance required by the coating cycle.
Sa 2 and Sa 2½
Sa 2½ blasting guarantees a higher level of cleanliness than Sa 2 and is recommended when high anti-corrosion performance is required.
The choice of grade depends on the operating environment and the required performance.
Anti-corrosion protection
The foundation of cycles intended for aggressive environments.
In cycles intended for aggressive environments, sandblasting is the foundation for achieving high anti-corrosion performance. Correct preparation makes it possible to maximise the effectiveness of subsequent treatments and significantly increase the durability of the part.
e-coating
powder coating
liquid coating
anti-corrosion primers and undercoats

FAQ
What is the difference between Sa 2 and Sa 2½ sandblasting?+
Sa 2½ blasting guarantees a higher level of cleanliness than Sa 2 and is generally used when high anti-corrosion performance and greater durability of the coating cycle are required.
Is sandblasting always necessary before coating?+
It depends on the condition of the substrate and the required performance. In higher-performing anti-corrosion cycles it is often the ideal solution to ensure adhesion and durability.
Can sandblasting be combined with e-coating?+
Yes. The combination of sandblasting, e-coating and final coating makes it possible to achieve one of the most effective protection cycles for components intended for particularly aggressive environments.
