Which technical coatings should be used to protect mixers and agitator shafts?
Sofiplast provides custom technical coatings including anti-corrosion, anti-abrasion, and ACS-compliant solutions for mixers and agitator shafts used in the chemical, pharmaceutical, and polymer industries. These treatments help extend equipment lifespan, reduce material buildup, and ensure hygiene, safety, and long-term reliability in sensitive industrial processes.
In the chemical, pharmaceutical, and polymer processing industries, mixers and agitator shafts operate under highly demanding conditions. The continuous agitation of abrasive, corrosive, or viscous products generates severe mechanical stress, progressive chemical attack on metallic surfaces, material buildup, and repeated friction on moving components.
These operating conditions can result in premature equipment wear, unplanned downtime, and reduced process efficiency, directly affecting both productivity and blend quality.
To address these challenges, Sofiplast develops custom technical coatings specifically engineered for each operating environment.

Our coating solutions to protect mixers and agitator shafts.
Technical coatings and anti-corrosion solutions for mixers and agitator shafts
Mixers and agitator shafts used in the chemical industry are continuously exposed to aggressive substances such as concentrated acids, alkalis, organic solvents, and reactive effluents. Over time, these corrosive environments can degrade metallic surfaces, affecting mechanical integrity, equipment lifespan, and process reliability.
To address these challenges, Sofiplast offers a range of high-performance anti-corrosion coatings specifically engineered for the demanding conditions of chemical mixing and agitation systems.
Depending on the products being processed, we apply:
- Fluoropolymer coatings such as Halar® (ECTFE), PFA and FEP
- Technical epoxy resin coatings
These treatments create a highly resistant and chemically inert protective barrier capable of withstanding acidic and alkaline attack, intensive cleaning cycles, and thermal variations.
Technical coatings and anti-abrasion solutions for mixers and agitator shafts
Mixers and agitator shafts are exposed to demanding mechanical conditions, including the agitation of solid materials, high shear forces, and repeated contact with abrasive powders or suspended particles. Over time, these operating conditions can cause premature surface wear, affecting mixing performance and process stability.
To improve abrasion resistance in these harsh environments, Sofiplast applies technical coatings such as:
- Sprayed polyurethane coatings
- Rilsan® polyamide coatings
These polymer-based materials create a durable and flexible protective layer capable of absorbing impacts, reducing friction-related heat, and providing long-lasting protection for mechanical components.
Technical coatings and ACS-compliant treatments for mixers and agitator shafts
Certain chemical and industrial processes require strict standards regarding chemical neutrality, product purity, and regulatory compliance, particularly for applications involving contact with drinking water or other sensitive fluids covered by ACS (Attestation of Sanitary Conformity) requirements. To meet these demands, Sofiplast offers ACS-compliant surface treatments based on technical fluoropolymer coatings and PPA (Polyphthalamide).
These materials provide excellent chemical resistance, high thermal stability, and outstanding durability against aggressive cleaning agents, while minimizing the risk of contamination or substance migration.When applied to mixers and agitator shafts, these coatings create a durable protective barrier that meets strict sanitary and regulatory requirements.
They help maintain equipment cleanliness, reduce cross-contamination risks, and ensure reliable long-term operation in sensitive industrial environments.
Our eco-friendly stripping processes
Before applying technical coatings to mixers and agitator shafts, proper surface preparation is essential to ensure optimal adhesion and long-term coating durability. At Sofiplast, we use an eco-friendly stripping process based on natural, biodegradable, and reusable plant-based media such as corn starch, wheat, and fruit shells.
This gentle and non-abrasive method replaces more aggressive techniques including sandblasting, laser cleaning, and intensive chemical stripping. Thanks to this approach, the integrity of complex geometries and stainless-steel or specialty-alloy components is preserved while ensuring excellent coating adhesion.
Eco-friendly stripping also helps reduce the environmental impact of surface treatment operations, which is a major advantage in sensitive industries such as chemicals, pharmaceuticals, and polymers.
