About Surface Finishing

The benefits of architectural coatings are evident on thousands of commercial, industrial, government, residential, historic and institutional buildings around world. Architectural coatings like Powder Coating, PVDF, FEVE ,Wood Effect finishes and Anodizing on metal has been the finish of choice for superior, more colorful, longer lasting and long lasting durability.

Powder Coatings

Powder coating is the technique of applying dry paint to a part in the form of a fine powder which is electrically charged. The part is electrically 'earthed' so the powder is attracted to the part and stays in place through static electricity. The part is then placed in an oven and is subject to temperature which melts the polyester and allows the finish to flow and cure before the part is cooled and ready to use.

Powder coating differs from 'wet paints' which typically use a solvent where the solids are in suspension in a liquid carrier which must fully evaporate before the finish is ready to use.

PVDF Coatings

PVDF is the abbreviation for polyvinylidene difluoride. PVDF is a fluoropolymer resin.PVDF resin-based architectural coatings provide high-performance durability for metal building products. These resin systems are available for both liquid and powder coatings. PVDF resin-based coatings are combined with the hardness of acrylic to deliver durable, superior-performance coating systems that withstand the test of weather and time.

Tested under extreme conditions, these coatings are proven to resist humidity, fading, chalking, abrasions and most chemicals, while retaining the intended color, gloss and appearance.

FEVE Coatings

FEVE coatings are the next generation architectural coating technology. Fluor polymer coatings are as highly durable coatings that can maintain their initial performance for long period. FEVE resins have characteristics of both fluoropolymers and hydrocarbons. FEVE based powders (Interpon D-3020 Series from Akzo Nobel and Durasol from Jotun) are single coat applications when applied to aluminum.

The unique Fluorine- Carbon bond and thermosetting properties of feve resin means the same ( or better) levels of durability and protection are executed in a single coat. Feve resin based powders retain their color and gloss extremely well and will meet and exceed the weathering performance requirements of AAMA 2605 and Qualicoat Class 3.

Wood Effect Finish.

The next generation of powder coating is here. In this time of LEED and GREEN builds, powder coating now offers a cosmetically appealing substitute for wood and natural stone without harming the environment.

Wood effect finishing is a special powder coating process based on the latest technology in the surface finishing. It enhances interior and exterior finishing with the appearance of high end aesthetic look of wood having the durability and strength of Metals. Wood grain effect finishing is now becoming more and more popular in the fields of architectural decoration it is a boon to the architects, builders and manufacturers looking to provide a alternate and different solution to customers looking for new aesthetics.

As we search to integrate alternative materials into today's building and design, this new process allows for conservation of our natural resources as well as an alternative to conventional finishes. With low to no VOC's, powder coating is paving the way for a greener future.

Anodizing

Anodizing is an electrochemical process that enhances the aluminum's natural oxide surface layer by forming an even more durable oxide film that can have a variety of colors. The lifetime of the finish is proportional to the thickness of the anodic coating applied. Aluminum oxide is a hard, durable, weather resistant substance that protects the base metal. The coating grows from the base aluminum metal by this electrochemical process.

The coating is integral to the metal and cannot peel or flake. The structure of the coating is many small hexagonal pores, which are filled with a "seal" that hydrolyzes these pores to fill them with inert aluminum oxide. This characteristic makes anodizing an excellent choice for the use in high- traffic areas where resistance properties are important.
