Pre-painted aluminium paint compositions

admin — Wed, 24 Aug 2016 04:06:21 +0000

Vestis products are coated using a specialist polyester paint.

When it comes to pre-painted aluminium, there are four coat application methods, each comprising of four main components.

More than 90 per cent of pre-finished metals are made with liquid paint. The remaining 10 per cent use laminate film. Our range of pre-painted aluminium finishes, Vestis, from Mazzonetto, uses liquid paint. Wet coatings have four main components:

Binders
Solvents
Pigments
Additives

Binders

Binders characterises different paint methods. Often pre-coated aluminium and steel will be refereed to, or classified by its binder. Binders give paint structure and there are four varieties; polyester, polyurethane, polyvinylidene fluoride (PVdF), and plastisol (PVC). Each type has its own sub-classes, where different chemical compositions create various levels of quality and durability.

Vestis is considered a polyester product. Traditionally polyester paint was believed to limit material flexibility and durability. Vestis differs from standard polyester coatings, as it sits within a sub-section, called high durability polyester paint. This specialist coating provides Vestis with a 35 micron layer finish, instead of polyester paint’s standard offering of 20-25 microns. High durability polyester paints create improved surface performance, flexibility, and exceptional UV resistance.

Solvents

Solvents help paint achieve a reliable smooth film across a product’s base material, prior to curing. Solvent are added to ensure the paint will flow well onto raw metal. Without reliable paint flow, achieving a smooth, consistent finish is near impossible.

Pigments

Pigments create paint colour. In addition to colouring raw metal coil, pigments also determine some physical performance properties; such as corrosion resilience. Even coated aluminium is prone to corrosion. No mater how many layers of paint are applied, the product is still metal at its core. Deterioration can occur during coil storage, and after installation. The pigment used in Vestis pre-painted aluminium provides a 40 year corrosion warranty, on applications located more than 1 km from the coast. For information on coastal warranties, please contact us to discuss your options.

Additives

Additives give pre-painted products their point of difference. These supplements can benefit production speed, UV stability, surface lustre and scratch, chemical and salt resistance.

An introduction to Zintek® zinc

admin — Wed, 17 Aug 2016 01:08:02 +0000

Zintek® zinc, beauty, long life and authenticity.

Zinc has been used in architectural applications since the 17th century. Today, zinc remains the most widely used, non-ferrous roofing and cladding material in Europe. Locally, as sheet metal cladding and roofing systems continue to gain popularity, zinc is fast becoming a favourite among architects, builders and homeowners.

In 2012, Architectural Metals Australia (AMA) forged an official relationship with Zintek®; becoming their Australia and New Zealand distribution partner. Zintek® is a market leader in Italy, specialising in boutique zinc manufacturing. It was Zintek’s® focus on environmental practices, innovation, and long lasting, aesthetically pleasing materials that attracted AMA’s leadership team.

As the first material in AMA’s collection, Zintek® set a quality and aesthetic precedent for future material selection. Considered an artisan product, Zintek® is capable of offering each project application its own unique aesthetic. Depending on material direction, and cladding profile, Zintek® will look different from one installation to another. At first, Zintek® presents a gloss surface. Over time, due to the material’s oxidisation process, it’s surface will become more matte.

Zintek® Specs

Coil width: 1100 mm
Thickness: 0.80 mm
Base material hardness: HV45
Composition: Zinc, titanium, copper
Environmental durability: Rural 100 years, urban industrial 60 years, industrial 40 years, marine 40 to 60 years

Zintek’s® unique etched appearance and mild grey colour, offers an unexpected aesthetic. In Europe Zintek’s® subtle, yet visually stimulating surface has enjoyed success in historic towns where new architectural forms must compliment traditional buildings. In Australia, Zintek’s® soft appearance has enjoyed successful applications on modern additions to heritage homes.

In addition to good looks, Zintek’s® chemical properties make it a flexible and durable specification option. As an alloy of zinc, Zintek® has a minimum fineness of 98.78 and a maximum of 99.86. Copper and titanium appear in Zintek® zinc. Copper increases tensile strength and titanium improves resistance. Together, they provide improved resistance to atmospheric corrosion and increase material workability – making Zintek® ideal for cladding and roofing manufacturing. In Australia, Zintek® has been specified in standing seam and interlocking systems, as well as some custom profile applications. Its flexibility and properties make Zintek® suitable for all sheet metal cladding and roofing systems.

Pre-painted coil coating

admin — Wed, 10 Aug 2016 04:21:27 +0000

The Coil Coating method is used to apply Vestis’ high durability polyester reinforced finish.

Coil Coating, is a continual, automated paint application process, commonly used on aluminium and steel. It’s fast, reliable, and capable of creating exceptionally durable, colour accurate, construction products. Purpose-built machinery, operated in purpose-built facilities, completes the coating process. On average a standard paint line is capable of coating around 200 meters of coil per minute. Unique coil stitching technology allows for continual production; minimising downtime between different coils. Pre-painted treatments follow strict and controlled manufacturing processes to ensure consistency and quality.

There are two main factors that set pre-coated metals apart from traditional paint coatings. The first, is uniformity of cleaning. Pre-treatment and coating and conducted are controlled in purpose built manufacturing environments. The second, is layer synergy. From pre-treatment to finished topcoats, each layer compliments and enhances another. While pre-painted metals are often identified by their topcoat, when looking at Coil Coating as a method, it’s important to remember each layer contributes to a product’s success.

Natural copper vs Vestis Copper

admin — Wed, 03 Aug 2016 01:23:19 +0000

To copper or to Vestis Copper?

Material selection is personal and subjective. It’s difficult to say one metal is clearly better or worse than another. When it comes to metal cladding and roofing, different materials will suit different applications. There are multiple variables to consider; such as overall design vision, personal taste, project location, cladding or roofing profile, adjacent materials, long-term building maintenance, and durability requirements.

Architectural Metals Australia (AMA), focuses on offering better material options for specifiers, installers and end users. Mazzonetto’s Vestis Copper provides a legitimate pre-painted aluminium specification alternative for those considering Natural copper.

Natural copper produces a spectacular and romantic aesthetic and its ageing process is inherit to its character; in some cases its captivating appearance is the main reason for specification. If aged copper is the look you seek, there’s nothing more beautiful than the real thing. However falling in love with the material’s original orange hue can be dangerous if you’re not prepared to also love how the metal will look in years to come. Copper can change from golden tones, to green, into deep browns, and eventually it can appear almost black. In addition to being aware of the metal’s colour evolution, one must also remember the ageing process won’t occur evenly across the materials surface. In some cases, this is the desired effect and it’s stunning. But if a rustic look wasn’t intended, copper applications can quickly become disappointing.

Vestis Copper offers a preserved version of natural copper’s original orange appearance. Providing a slightly patina surface, Vestis Copper duplicates the look of recently installed natural copper. However unlike natural copper, its appearance won’t alter over time.

Another key difference between natural copper and Vestis pre-painted aluminium, is base material cost. Large amounts of natural copper can become expensive. Vestis Copper is a cost savvy material solution (depending on project complexity), providing opportunity for budget conscious projects to enjoy the prestigious look of copper metal cladding.
