Argos ST roller coatings are the result of careful selection and proven operational processes.
At Argos ST, we produce quality roller coatings in 5 steps. From incoming to outgoing material control, everything is tested continuously to ensure a high-quality finished product.
Coating rollers with suitable raw materials guarantees a net gain in time and costs for our customers in the long term, with business growth due to the selection of intelligent techniques and treatments.
Solutions by Argos ST represent excellence in the field of roller coatings, where cheaper but lower-performance solutions, i.e. rubber roller coatings, can also be found.
Rubber roller coatings: pros and cons
Rubber roller coatings are widely used in industrial applications, since they are particularly suitable for sectors such as tanning, textiles, food and chemicals.
Since their purpose is to protect the rollers, they must have very specific features, such as high mechanical and thermal resistance, and protect the roller from the corrosive action of high temperatures and aggressive solvents. Rubber roller coatings do not, however, offer the same performance in every industrial sector, with resulting advantages and disadvantages.
- Advantages: they are inexpensive, reliable and highly efficient in the food, textile, chemical, tanning, etc., industries. They are versatile due to different surface finishes, from smooth to diamond-shaped, with transverse or longitudinal grooves. The composition of the rubber can withstand aggressive chemicals and high temperatures, protecting the rollers from damage and corrosion;
- Disadvantages: their effectiveness is significantly reduced when it comes to lightweight and/or slippery materials such as lightweight paper, nonwoven fabrics or high-speed production runs such as nappies, due to the difficulty in meeting specific traction criteria. Even for very heavy materials, the traction of rubber coatings is limited and unsatisfactory.
In all these cases, Argos ST roller coverings fill the functional void left by rubber coatings.
In addition to superior traction, Argos ST also offers corrosion protection with fluoropolymers, which are far superior to the best rubbers, as well as non-stick and anti-adhesive properties for a smoother production process. In addition, due to precise tensioning, Argos ST coatings enable faster winding, reducing machine downtime compared to rubber coatings.
Silicone roller coatings
Ideal for production processes that require highly non-stick surfaces, silicone roller coatings are particularly effective even with very strong glues (such as hot melt glue). They are therefore used in the production of adhesive tapes and on rollers used to spread hot melt adhesives.
Other areas of application include textiles, food and packaging, where they represent added value over classic rubber rollers.
Argos ST silicone coatings are made using Thermal Spray technology, developed to give the surface either slide or traction, hardness and elevated non-stick properties. In combination, the last two characteristics favour perfect tensioning in high-speed production lines.
