multicover® - the sustainable sealant on hot-dip galvanized steel strip

With excellent anti-fingerprint properties, multicover® is a multifunctional, nearly invisible protective coating on hot-dip galvanized steel strip. Powder coatings can also be applied directly to the product.

multicover is a sustainable sealant for hot-dip galvanized steel strip (Z).

A hot-dip galvanized steel strip treated with multicover features excellent properties, including good joinability, a sustainable seal and much more.

Direct cost savings through reduction of process steps

When using steel strip coated with multifcover®, the oiled part must not be degreased, rinsed or dried. The direct formability and excellent adhesive properties of the material make it possible to directly powder-coat or adhesive-bond the material after deep-drawing. This substantially reduces the processing costs.

The use of multicover and clearcover® eliminates the need for complex processing steps such as oiling, degreasing, rinsing and drying.

Multiple certifications

Extensive material certification is naturally a minimum requirement at voestalpine in our effort to provide high-performance additional treatments. Actual properties often go far beyond the standard minimum requirements.

voestalpine relies on internationally renowned certifications.

multicover®

multicover® is a high-performance and sustainable sealing technology.

Do you need a sustainable and permanent premium sealant with outstanding anti-fingerprint properties, excellent formability and excellent corrosion resistance? Then multicover® is the product of your choice.

multicover® is a multifunctional, almost invisible sealant (thin organic coating = TOC) on hot-dip galvanized steel strip (Z). Its outstanding properties make multicover® extremely versatile. It is alkali-resistant but can be removed with polar organic solvents. A tailor-made polymer matrix ensures highest corrosion stability, best formability, very good paintability and resistance to fingerprints (anti-fingerprint). Please see the EN 50979 standard for more information.

Direct cost savings through reduced number of process steps (oiling, degreasing, rinsing + drying)

When using steel strip coated with multicover®, the oiled part must not be degreased, rinsed or dried. The direct formability properties of the material make it possible to directly powder-coat the material after deep-drawing. This results in a considerable reduction in process steps and costs.

Typical applications

multicover® can be applied to a wide range of products.

House industry

Whether transporting, reshaping or overcoating. The applications are many. Anti-fingerprint solutions that lend products a perfect appearance even after repeated handling are particularly popular.

Construction industry

Excellent forming, good corrosion protection properties and good emulsion resistance for the highly efficient production and long service life of pipes and profiled sections.

Heating and ventilation industry

Durability and clean surfaces without fingerprints, even after assembly, coupled with good formability are highly valued properties in this industry.

Processing industry

Pre-material for profiled sections for product storage must arrive at the customer in uncorroded condition. multiface® additionally guarantees very good transport corrosion protection.

multicover® properties in comparison

multicover®, our thin organic coating, is the number 1 sealant and perhaps the most versatile product in our portfolio. Combined with excellent corrosion protection, used as a forming aid and for direct coatability, multicover® is the true high-tech surface treatment.
